  • Patent number: 11407974
    Abstract: The present invention relates to a mutant fungal strain of Penicillium funiculosum ‘MRJ-16’ characterized by the ability to produce high titer of enzyme mixture comprising FPase, CMCase, Cellobiase, ?-glucosidase, endoglucanase, ?-L arabinofuranosidase, ?-xylosidase, xylanase, pectinase, cellobiohydrase and oxidases and produce enzymes in the presence of a catabolite repressor molecule like glucose and/or xylose. The titer of enzyme mixture produced using mutant fungal strain MRJ-16 is at least two fold higher than naive Penicillium funiculosum strain NCIM 1228, when used in a fermentation process. The mutant strain ‘MRJ-16’ with high hydrolytic activity and catabolite derepressed character is having application in the method of degrading or saccharifying biomass to produce valuable products for example-bioethanol.

  • Patent number: 11261419
    Abstract: A method for preparing a hyper-cellulolytic catabolite derepressed mutants of ascomycetes fungus, especially variants of Penicillium funiculosum. Selection media used to isolate such variants include amorphous cellulose and a high concentration of glucose. Cellulase activities of mutant ID-10, in particular such as FPase and ?-glucosidase were 1.5 times higher than Penicillium funiculosum MRJ-16 (parent). Furthermore, fungal mutant morphology was changed and no pH adjustment was required throughout the enzyme production process.
