Abstract

Abstract Algae have been explored for renewable energy, nutraceuticals, and value‐added products. However, low lipid yield is a significant impediment to its commercial viability. Genetic engineering can improve the fatty acid profile of algae without compromising its growth. This study introduced the diacylglycerol acyltransferase (BnDGAT) gene from Brassica napus into Chlorella sorokiniana‐I, a fast‐growing and thermotolerant natural strain isolated from wastewater, which increased its intracellular lipid accumulation. Hygromycin‐resistant cells were selected, and enhanced green florescence protein fluorescence was used to distinguish pure transgenic cell lines from mixed cultures. Compared to the wild type, BnDGAT expression in transgenic C. sorokiniana‐I caused a threefold increase in non‐polar lipid and a twofold increase in polyunsaturated fatty acids. Nile red staining reaffirmed the presence of higher intracellular lipid bodies in transgenic cells. There was a substantial alteration in the fatty acid profile of transgenic alga expressing BnDGAT. The non‐essential omega 9 (C18: 1) fatty acid decreased (5%–7% from 18%), while alpha‐linolenic acid, an essential omega 3 fatty acid (C18: 3), was increased (23%–24% from 11%). This study substantiates a valuable strategy for enhancing essential omega‐3 fatty acids and neutral lipids to improve its nutritional value for animal feed. The increased lipid productivity should reduce the cost of producing fatty acid methyl esters (FAME). Improved FAME quality should address the clouding issues in cold regions.

Abstract

Synthesized astaxanthin (ASX), stereoisomers of 3S,3′R, 3R,3′R, and 3S,3′S, have over 95% market share and have relatively poor antioxidant and bioactivity properties, with persistent issues in terms of biological functions, health benefits, and biosafety if compared to natural ASX. Bioprospecting of new microalgal strains could be vital for a new source of powerful antioxidant (ASX). In this study, a new algal strain was isolated from the Indian foothills of the Himalayas. Its identity was discerned by morphological and DNA barcode studies. It is a unicellular spheroidal cell-shaped alga with 100–200 μm diameter. The isolate has 93.4% similarity to Dysmorphococcus globosus species based on 18S-rDNA phylogenetic analysis and named as D. globosus-HI (HI stands for Himalayan India). Its growth and major cellular components (carotenoids, carbohydrates, protein, lipids, fatty acid profile, and ASX) were optimized using the seven different culture media. The highest biomass (1.14 g L−1) was observed in the MBBM medium, with a specific growth rate (0.087 day−1), division/day (0.125), and cellular yield (6.16 x 106 cells/mL). The highest carotenoids (1.56 mg g−1), lipids (32.5 mg L−1), and carbohydrates (135.62 mg L−1) were recorded in the 3N-BBM medium. The maximum ω3-FAs (17.78%), ω6-FAs (23.11%), and ω9-FAs (7.06%) were observed in MBBM, JW, and BG-11 medium respectively. The highest amount of antioxidant ASX was accumulated in the 3N-BBM medium (391 mg L−1). It is more than any other known algal species used in the production of natural ASX. The optimized biochemical studies on the D. globosus-HI strain should fulfill the increasing demand for natural ASX for commercial application.

Author

Wafaa Fathi Zohir, Vikas U. Kapase, Prachi Nawkarkar, and Shashi Kumar

Abstract

Microalgae are a diverse group of microscopic and highly efficient photosynthetic organisms with rapid growth that contains a wide range of biochemical components such as pigments, lipids, carbohydrates, and proteins, making them a viable feedstock for various commercial applications in biofuel production, nutraceutical, pharmaceutical, and environmental sectors. Life-cycle assessment (LCA) is one of the most appealing and attractive tools used nowadays by the scientific and decision-makers communities to ensure environmentally sustainable production/consumption of various products. It is a systematic and standardized methodology that has turned into a crucial communication tool for the projects, the target markets, and the general public. Recently, LCA has been applied to quantify algal biofuels' environmental sustainability. As a result, the importance of algal life cycle analysis, its consequences, and contribution to the circular economy will be discussed in this chapter in terms of developing industrial applications.

Abstract

Optimizing the production of the high-value renewables such as OMEGAs through pathway engineering requires an in-depth understanding of the structure-function relationship of genes involved in the OMEGA biosynthetic pathways. In this preliminary study, our rationale is to identify and characterize the ∼221 putative genes involved in production of OMEGAs using bioinformatic analysis from the Streptophyte (plants), Chlorophyte (green algae), Rhodophyta (red algae), and Bacillariophyta (diatoms) lineages based on their phylogenomic profiling, conserved motif/domain organization and physico-chemical properties. The MEME suite predicted 12 distinct protein domains, which are conserved among these putative genes. The phylogenomic analysis of the putative candidate genes [such as FAD2 (delta-12 desaturase); ECR (enoyl-CoA reductase); FAD2 (delta-12 desaturase); ACOT (acyl CoA thioesterase); ECH (enoyl-CoA hydratase); and ACAT (acetyl-CoA acyltransferase)] with similar domains and motif patterns were remarkably well conserved. Furthermore, the subcellular network prediction of OMEGA biosynthetic pathway genes revealed a unique interaction between the light-dependent chlorophyll biosynthesis and glycerol-3-phosphate dehydrogenase, which predicts a major cross-talk between the key essential pathways. Such bioinformatic analysis will provide insights in finding the key regulatory genes to optimize the productivity of OMEGAs in microalgal cell factories.

Abstract

Optical fiber communication technology is beneficial to satisfy today's increasing demands for high data rates. This need for higher data rates and bandwidth has driven the fast development of fiber optic communication technologies. But at the same time, some undesirable nonlinear effects in the optical fiber medium become noticeable at high power levels. These fiber nonlinearities affect the optical fiber communication systems. The light signal in Wavelength Division Multiplexing (WDM) system can be degraded due to nonlinear impairments in the fiber. So it has become necessary to study the nonlinear effects. In this paper, nonlinear effects called Self-Phase Modulation (SPM) and Four-Wave Mixing (FWM) are observed. Factors responsible for variations in SPM and FWM effects are analyzed using OptiSystem simulation tool.

Abstract

We update the results of a search for the Standard Model neutral Higgs boson using a data sample corresponding to 1 062 000 hadronic Z decays. We exclude the existence of the Minimal Standard Model Higgs boson in the mass range 0 -%< mH < 57.7 GeV at the 95% confidence level., Facultad de Ciencias Exactas

Abstract

We report on a general search for neutral and charged Higgs bosons with no assumption that the Higgs sector consists of a single doublet as in the minimal standard model. No signal inconsistent with background is observed in any of the decay channels analysed. From the results of direct searches, model independent limits on Higgs bremsstrahlung and on Higgs pair production from the Z0 are presented. We interpret the bremsstrahlung limits in the general two-doublet model. Z0 lineshape measurements further restrict the parameter space available in the two-doublet model. Finally, the results are interpreted in the framework of the minimal supersymmetric extension of the standard model., Facultad de Ciencias Exactas

Abstract

We have searched for anomalous Z --> gamma gamma gamma events with the L3 detector at LEP. No significant deviations from the expected QED e(+)e(-)-->gamma gamma gamma events are observed. The branching ratio upper limit for a composite Z decaying directly into three photons is found to be 1.0 x 10(-1) at 95% C.L. The branching ratio upper limits for the process Z-->gamma X,X-->gamma gamma are in the range of 0.4 to 1.3 x 10(-5), depending on the mass and width of the scalar particle X. In the context of a model with magnetic monopoles coupling to the Z, we find BR(Z-->gamma gamma gamma) < 0.8 x 10(-5) at 95% C.L; this results in a lower mass limit of 510 GeV for a magnetic monopole.

Abstract

We report on a detailed study of the energy and particle flow in the event plane of three-jet events q(q) over barg$ and radiative two-jet events in hadronic Z decays recorded with the L3 detector. We find a significant decrease in particle and energy density in the angular region between quark and antiquark jets for q(q) over barg$ events as compared with events. Several QCD model predictions are compared with the observed effect.

Abstract

Total and differential cross sections for the process e(+)e(-) --> gamma gamma(gamma), and the total cross section for the process e(+)e(-) --> gamma gamma gamma, are measured at energies around 91 GeV using the data collected with the L3 detector from 1991 to 1993. We set lower limits, at 95% CL, on a contact interaction energy scale parameter Lambda > 602 GeV, on the mass of an excited electron m(c)* > 146 GeV and on the QED cut-off parameters Lambda(+) > 149 GeV and Lambda(-) > 143 GeV. Upper limits are also set on the branching fractions of Z decaying into gamma gamma, pi degrees gamma and eta gamma of 5.2 x 10(-5), 5.2 x 10(-5) and 7.6 x 10(-5) respectively. The reactions e(+)e(-) --> rho(+)rho(-)n gamma (rho = e, mu, tau) are studied using the data collected from 1990 to 1994. The data are consistent with the QED expectations.

Abstract

We have studied the four-fermion processes ee --> eeee, eemumu, eetautau, mumumumu, mumutautau, eeqq and mumuqq with the L3 detector at LEP. For an integrated luminosity of 36 pb-1, corresponding to 960000 hadronic Z decays, we find a total of 67 candidate events. The rate and kinematical distributions are found to be consistent with first order Monte Carlo calculations based on the Standard Model. No significant structure is seen in the dilepton invariant or recoil mass spectra.

Abstract

In this report we summarize the major results from the first three years of running of the L3 detector at the Large Electron Positron collider (LEP). The L3 detector was designed to measure electrons, photons and muons with high precision; it has achieved (DELTAE/E) almost-equal-to 1.4% for electrons and photons at E = 45 GeV and (DELTAp/p) almost-equal-to 2.5% for muons at p = 45 GeV. Most of the experimental results presented are based on approximately 500 000 Z events. The data provide four independent checks of the Standard Model weak neutral currents to an accuracy of almost-equal-to 1%. These are: the measurement of Z parameters; the measurement of the forward-backward charge asymmetry of lepton pairs; the measurement of asymmetry parameters from Z --> bbBAR decays; and the measurement of the tau lepton polarization asymmetry. The data also provide information on weak charged currents from measurements of b hadrons such as decay width, lifetime, and B0-B0BAR mixing, and from measurements Of tau leptons such as their lifetime and branching ratios. The large number of Z events and the resolution of the L3 detector allow precision tests of QED and QCD, including the production of pi0, eta and hard photons. Leptonic final states with hard isolated photons are analyzed and high mass photon pairs are observed. Higgs boson production has not been observed and limits are given in the context of the Standard Model and its supersymmetric extensions. We also present upper limits on rare Z decays such as Z --> gammagammagamma and on flavor violating decays such as Z --> etau, mutau. Finally, upper limits obtained in the search for various new particles and new interactions are reported.

Abstract

We have measured the total and differential cross sections of the reaction e+ e- --> gamma-gamma(gamma) at center-of-mass energies around 91 GeV, with an integrated luminosity of 14.2 pb-1. The results are in good agreement with QED predictions. We set lower limits, at 95% confidence level, on the QED cutoff parameters of LAMBDA+ > 139 GeV, LAMBDA- > 108 GeV and on the mass of an excited electron of m(e*) > 127 GeV. We searched for Z0 rare decays with photonic signatures in the final state. Upper limits, at 95% confidence level, for the branching ratio of ZO decaying into pi-0-gamma/gamma-gamma, eta-gamma and gamma-gamma-gamma are 1.2 x 10(-4), 1.8 x 10(-4), 3.3 x 10(-5) respectively.

Abstract

A more precise determination of the B0-B0BAR mixing parameter in Z0 decays based on a fourfold increase in statistics has been made using the 1990 and 1991 L3 data. The analysis of the dilepton events, muons and electrons, gives: chi(B) = 0. 121 +/- 0.017 (stat) +/- 0.006 (sys). Using the value of chi(d) measured at the UPSILON(4S) we derive the following limit for chi(s): chi(S) > 0.16 (90% CL).

Abstract

We report on the measurement of the leptonic and hadronic cross sections and leptonic forward-backward asymmetries at the Z peak with the L3 detector at LEP. The total luminosity of 40.8 pb ???1 collected in the years 1990, 1991 and 1992 corresponds to 1.09??10 6 hadronic and 0.98??10 5 leptonic Z decays observed. These data allow us to determine the electroweak parameters. From the cross sections we derive the properties of the Z boson: assuming lepton universality. We obtain an invisible width of ?? inv =496.5??7.9 MeV which, in the Standard Model, corresponds to a number of light neutrino species of N v =2.981??0.050.

Abstract

We report on a search for the neutral and charged Higgs bosons predicted by models of spontaneous symmetry breaking with more than one Higgs doublet field. No signals are observed. We set model-independent limits on masses or branching ratios of singly and pair-produced neutral and charged Higgs bosons. In addition, we interpret our results in the framework of a general two-doublet Higgs model and the Minimal Supersymmetric extension of the Standard Model.

Abstract

The ratios of cross sections, Rb = a(e+e- → bb)/a(e+e- → hadrons) and R, = cr(e+e- → E)/a(e+e- → hadrons) and , and the forward-backward asymmetries and , have been measured by the four LEP experiments at centre-of-mass energies close to the Z boson mass, using a variety of heavy flavour identification techniques and analysis methods. The procedure adopted to combine these measurements is described here. It takes into account the statistical and systematic correlations among the measurements and their interdependences in a χ2 minimization. The procedure is illustrated using published measurements., Facultad de Ciencias Exactas

Abstract

A study of twelve distinct decay channels of the ηc has been performed with the L3 detector at LEP, for an integrated luminosity of 30 pb−1. Summing all channels, 28 candidate events have been identified, with an estimated background of 11 events. The two-photon radiative width is evaluated to be Γγγ(ηc ) = 8.0 ± 2.3 ± 2.4 keV., Facultad de Ciencias Exactas

Abstract

The L3 detector at LEP has been used to determine the number of light neutrino families by measuring the cross section of single photon even in e+e- collisions at energies near the Z0 resonance. We have observed 61 single photon candidates with more than 1.5 GeV of deposited energy in the barrel electromagnetic calorimeter, for a total integrated luminosity of 3.0 pb-1. From a likelihood fit to the single photon cross sections, we determine N(nu) = 3.24 +/- 0.46 (statistical) +/- 0.22 (systematic).

Abstract

Media temporalities of the elderly : evolutions in stability This article shows the context of analysis and the first results of a research on media temporalities of the elderly. Several works have finely analysed the diversity of the media practices and studied meanings of media uses. I wish to continue these analyses by insisting on the evolutionary and dynamic aspect of the practices and temporalities of users having expanded, enhanced, so called "interactive" radio and especially television programming. A priori, the elderly, upon retirement, have a "full-time free time". Their media practices seem strongly influenced by their first experiments ; the appropriation of the various peripheral accessories which gradually came with the media, to the latest digital ones, seems to reinforce their habits of watching television. Their representations and relations with times and media are very far away from the image of television like omnipresent media or "devourer of time". Rather, their media practices are to be understood like a temporality of the occupation, according to the expression of Gerard Derèze, characterized by interest and utility. A particular glance at the users who do not carry out a systematic selection of the programs, accepting the unforeseen, highlights an approach of media and time that allow "useful encounter" which I would qualify in a first stage by : "chance and encounter" and "random and the following". The few points presented here make me assume that the global relation of the autonomous elderly persons to the media can evolve when confronted to their new temporal framework and the new program offer, whereas their representations and use of the media remain quite stable.
