Abstract

Background: Omics approaches are widely applied in the field of biology for the discovery of potential CAZymes including whole genome sequencing. The aim of this study was to identify protein encoding genes including CAZymes in order to understand glycans-degrading machinery in the thermophilic Caldicoprobacter algeriensis TH7C1T strain., Results: Caldicoprobacter algeriensis TH7C1T is a thermophilic anaerobic bacterium belonging to the Firmicutes phylum, which grows between the temperatures of 55 °C and 75 °C. Next generation sequencing using Illumina technology was performed on the C. algeriensis strain resulting in 45 contigs with an average GC content of 44.9% and a total length of 2,535,023 bp. Genome annotation reveals 2425 protein-coding genes with 97 ORFs coding CAZymes. Many glycoside hydrolases, carbohydrate esterases and glycosyltransferases genes were found linked to genes encoding oligosaccharide transporters and transcriptional regulators; suggesting that CAZyme encoding genes are organized in clusters involved in polysaccharides degradation and transport. In depth analysis of CAZomes content in C. algeriensis genome unveiled 33 CAZyme gene clusters uncovering new enzyme combinations targeting specific substrates., Conclusions: This study is the first targeting CAZymes repertoire of C. algeriensis, it provides insight to the high potential of identified enzymes for plant biomass degradation and their biotechnological applications.

Abstract

Nigella sativaseed oil is widely used as an anti-inflammatory, antioxidant, and anticancer agent. However, its insolubility in aqueous media and low stability limit its practical biological applications. The aim of this study was to formulate and characterize Nigella sativaseed oil (NO) using β-cyclodextrin (β-CD). The preparation of the inclusion complexes was carried out by co-precipitation method and then validated by Fourier transform infrared spectroscopy (FTIR), X-ray powder diffraction (XRD), differential scanning calorimetry (DSC), and dynamic light scattering (DLS). The encapsulation efficiency of the inclusion complexes formed was about 80.4% and 88.2% for the two ratios studied, 1:2 and 1:4 (w:w), respectively. The study showed that the Nigellaoil encapsulation preserved the antioxidant activity against DPPH and, in particular, enhanced the antibacterial activity against Salmonella typhimurium, Staphylococcus aureus, and Bacillus cereusby a factor reaching fourfold. A minimum inhibitory concentration similar to that of ampicillin (0.078 mg/mL) was observed against Salmonella typhimuriumwhen the complex β-CD/NO 1:4 (w:w) was used. The cytotoxicity study showed that the oil encapsulation in β-CD retained its anti-proliferative activity against HeLa cancer line cells. Using SwissADME prediction, the pharmacokinetic profile of all identified oil compounds was evaluated to define their absorption, distribution, metabolism, and excretion (ADME) properties. The results support the use of encapsulated Nigellaoil for active food packaging or pharmaceutical formulations.
