Abstract: The present invention relates to a process for valorization of low-cost alkane rich feedstock. More specifically, the present invention relates to the selective conversion of alkane rich kerosene to value-added products like mono/dicarboxylic acid, fatty acids and biosurfactants using mutant yeast strain and a heterogenous nano-catalyst. The present invention also provides a mutant yeast strain for selective conversion of alkane rich refinery stream from a substrate containing hydrocarbons. The mutant yeast strain of the present invention is able to consume the sulfur content in the feed and results in the desulfurization of the alkane rich feedstock.

Abstract: The present invention relates to a process for production of ethanol from lignocellulosic biomass via modified simultaneous saccharification and co-fermentation (SSCF), wherein the process includes transferring or recirculation of residual biomass from a first batch of SSCF to a second batch of SSCF at the time of enzymatic hydrolysis and then transferring the residual biomass in part or completely from the second batch of SSCF to a third batch of SSCF process to its hydrolysis reaction step. Overall, the average ethanol yield from three conjugative batch of SSCF is 5.06% higher compare to the single batch of SSCF without adding any additional enzyme, and hydrolysis time.

Abstract: The present invention provides an improved process for high titer lactic acid production using simultaneous saccharification and co-fermentation process using acid treated lignocellulosic biomass. The process comprises of pretreating lignocellulosic biomass comprising C5 and C6 sugars with dilute acid and superheated steam at a temperature ranging from 150-210° C.; neutralizing the pretreated lignocellulosic biomass of step (i) with NaOH pellets; and adding cellulase enzyme in the range of 1.5 to 10 FPU/g, bacteria, nutrients and buffering agent to the neutralized slurry obtained in step (ii) for hydrolysis and co-fermentation of C5 and C6 sugars at a temperature ranging from 40-45° C. for a period of 120-144 hours to obtain lactic acid. The process of the present invention requires simple nutrients and results in high titer lactic acid production within shortest duration of time.
