Abstract: The present invention relates to a method for reducing or preventing the formation or activity of a corrosion-associated biofilm on a metal surface, wherein the method comprises contacting the metal surface with a liquid composition comprising biocidal preparation. The present invention also relates to a microbicidal composition comprising at least one alcohol, one liquid hydrocarbon, a bacteriophage immobilized on a magnetic nanocomposite, at least one phage releasing reagent and one stabilizer. The microbicide composition and method of the present invention reduces biofilms on surfaces, and consequently, reduces, mitigates, or eliminates MIC in internal surface of the oil transporting pipelines.

Abstract: The present invention provides a composition and a method for mitigating formation or activity of a corrosion-associated biofilm on metal surfaces of pipelines. The pipelines are first treated with pigs i.e. bi-di pigs for removing/disturbing biofilm, followed by microbial treatment i.e. application of microbecidal composition. The microbecidal composition comprising at least one alcohol, one corrosion inhibitor, one surfactant, one biocide and a lignin-based nanoparticle. The lignin-based nano particle is functionalized with amine functionalizing agent. The present composition and method is eco-friendly, as low concentration is sufficient and further, regular dosing is not required for MIC control.

Abstract: The present invention relates to a process for continuous production of second-generation ethanol from lignocellulosic biomass via continuous simultaneous saccharification and co-fermentation (SSCF) process, wherein the process includes a first fermentor vessel for selectively fermenting C5 sugars and then Continuous transferring the fermented biomass to a second fermentor vessel for hydrolyzing the fermented biomass and then Continuous transferring the hydrolysate to a third fermentor vessel for selectively fermenting C6 sugars to obtain ethanol. Overall, the ethanol yield achieved was up to 70% for both C5 and C6 sugars from pretreated biomass; and C5 utilization exceeded 95% after SSCF.

Abstract: The present invention relates to a method for obtaining a high titer of enzyme mixture comprising cellulases, hemicellulases and β-glucosidases in reutilization of waste water generated during hot water extraction of lignocellulosic biomass or biorefinery waste water using Penicillium funiculosum MRJ-16 mutant strain. The cellulose or lignocellulosic biomass used in the fermentation process is selected from the group consisting of rice straw, wheat straw, corn stover, cotton stalk or a combination thereof. The enzyme mixture obtained by the present process is used for the saccharification of acid pretreated lignocellulosic biomass.

Abstract: The present invention relates to a process for production of ethanol from lignocellulosic biomass via modified simultaneous saccharification and co-fermentation (SSCF). In the present invention, enzymatic hydrolysis is preceded by mainly C5 sugar fermentation and low enzymatic hydrolysis and succeeds by mainly C6 sugar fermentation at different temperature and duration. This resulted into reduction in enzyme dosage and process time with increase in ethanol yield from acid pretreated biomass.
