Combined effects of high hydrostatic pressure and specific fungal cellulase improve coconut husk hydrolysis

摘要: Abstract Cellulosic ethanol production may serve in the development of a viable renewable fuel. An important contribution to bio-economy and sustainability could be achieved by using coconut husks, thousands tons which are discarded every day tropical regions. However, high costs have hindered this application common refuse. In work, we propose process improve husk hydrolysis for production. To achieve improvement, applied combined method. First, treatment based on hydrostatic pressure (HHP) increased hydrolytic performance cellulases recalcitrant husk. Second, isolated cellulase from submerged fermentations coconut-specific fungi were used under pressure. Interestingly, specific produced these outperform industry standards pressurised conditions. Additionally, HHP improves cellobiase activity, reduces cellobiose-dependent inhibition biomass hydrolysis. increase factor 2 was as result effects action fungal cellulases. use new fungus, Penicillium variabile, source combination with novel
