Abstract Five successive deformation phases have been identified from structural analysis of granitoid and gneissic rocks of the study area. The magnetic foliation data of the studied granitoids show two distinct NW and NE trending sets. The NW trending magnetic foliation is found to be essentially parallel to the mesoscale planar structures of regional D1-D2 deformations and is thus correlated with the D1-D2 phases. On the contrary, the NE trending magnetic foliation appears to be kinematically compatible with the NW-SE compression direction deciphered from conjugate ductile shear zone patterns of the D3 event. Combining AMS, field and microstructural data, the granitoid outcrop have been separated into older D1-D2 and younger D3 domains. The published geochronological data from the area when compared with the established D1-D2 and D3 domains, shows a good correlation pointing tentatively the timing of the D1-D2 deformation phase to be ∼2550 Ma while the D3 phase to be ∼2524 Ma. Hence the study highlights the importance of combining AMS data with field and microstructural studies to constraint the timing of regional successive deformation imprints. It also helps to identify the chronologically separated emplacement phases of the granitoid massif in question, which would not have been possible otherwise. Highlights • The deformed Neoarchaean granitoids of the study area in the EDC, south India show evidences of five successive deformation imprints (D1-D5). • The D1-D3 phases represent early ductile episodes which are well documented from the EDC. • The hitherto undetected D4-D5 phases represent essentially brittle shallow crustal events of which the overlying Mesoproterozoic Srisailam Formation manifests the D5 phase only. • The observed magnetic fabrics from granitoids depict NW-SE and NE-SW trends which are correlated with D1-D2 and D3 deformation phases respectively. • AMS data along with field, microstructural and published geochronological data help to constraint the chronology of successive deformation imprints and identify the separate emplacement phases in the granitoid massif.

• Viscozyme helps in increased monomeric sugar generation. • 14.32 g/l of glucose and 7.35 g/l of xylose are recovered with viscozyme. • Thermal deactivation of viscozyme is investigated. • Lower fractal dimensions and increased binding capacity of substrate and enzyme are observed. • Diffusion limitations of the present enzyme-substrate system is investigated. Development of a novel, integrated production of C 8 ester butyl butyrate (BuB), a promising supplement for diesel/jet-engine fuels, from lignocellulose derived C 5 and C 6 sugars is attempted by means of smart and innovative process design. In the pathway, enzymatic hydrolysis of biomass with high solid loading is an important step which requires reduced amount of water supply and energy input. However, increased substrate loading lead to diffusion limitations of enzymes, on top of nonproductive absorption of enzymes. Addition of ß-glucosidase over cellulase is another reason to increase the cost of enzymes. Viscozyme can be considered as a troubleshooter in these cases where it can offset high substrate loading and increased monomeric sugar generation. In the present study, 17.61 g/L of glucose, along with 7.43 g/L of xylose, have been recovered with a viscozyme concentration of 54.4 g/L. Additionally, thermal deactivation of viscozyme has been investigated. The deactivation constant is found to be gradually increasing with escalated enzyme loading from 24.2 g/L to 54.4 g/L. In this study, it has been found that hydrolysis of biomass follows a first order pseudo-kinetics and the same is eventually used to determine the fractal kinetics of cellulose hydrolysis. Fractal kinetics showed that increment of enzyme concentration is associated with lower fractal dimensions and increased binding capacity of substrate and enzyme. Diffusion limitation of the present enzyme-substrate system has also been investigated. It is observed that faster diffusion, along with increased resistances, can be achieved with increased enzyme concentration. [ABSTRACT FROM AUTHOR]
