ABSTRACT: De novo sequenced genome of white-rot fungi Cerrena unicolor SP02 provide insights into food safety value-added utilization of non-food lignocellulolytic biomass
Project description:In this project, the transcriptomic data was obtained from the 6-day and 10-day submerged cultures of Cerrena unicolor sp. 87613 under PDA media, respectively. C.unicolor is reported to be an important medicinal fungus as well as an efficient laccase producer. Interestingly, C.unicolor sp.87613 presented a highest laccase production with ~420 U/mL at fermentation day 6, while the laccase production was reduced by ~27% at fermentation day 10. Therefore, these collected data were used to unveil the potential regulatory mechanism of laccase production. Besides, these transcriptomic data also provide essential data source for a better understanding of C.unicolor in various aspects.
Project description:In the present work, Abortiporus biennis, a white-rot fungus, was studied in regard to its lignocellulolytic enzymatic potential. Secretomics analyses, combined with biochemical methods, were employed to study the enzymatic machinery of the strain, after growth in corn stover cultures and xylose-based defined media. The results revealed the presence of all the necessary enzymatic activities for complete breakdown of the lignocellulosic substrate, while the prominent role of oxidative enzymes in the lignocellulolytic strategy of the strain became evident. Two novel laccases, AbiLac1 and AbiLac2, were isolated from the culture supernatant of this fungus.
