| Abstract |
Ethanol production from a cellulosic biomass has been realized as a potential way for sustainable circular economy. In this effort, pretreatment processes employed for the depolymerization of structural polymers of rice straw are detrimental and expensive. Here, a novel yeast strain Meyerozyma caribbica M72 was identified from mahua flower. An efficient process using mild sulfuric acid (0.8%) treatment at temperature 160 degrees C for 10 min, followed by saccharification with the identified novel yeast, was developed for ethanol production from rice straw. The morphological changes in rice straw upon treatment and saccharification were monitored with SEM, FTIR, XRD, and BET. Identified yeast was found to be able to utilize both pentose and hexose sugars of rice straw. Meyerozyma caribbica M72 from mahua flower was found to produce ethanol to the extent of 24.36 g/L at 32 degrees C and pH 7 from saccharified hydrolysate of rice straw in 48 h with 8% ethanol tolerance. |
