 Filamentous fungi have been found to be effective in producing cutinases, which are enzymes capable of breaking down the polymer cutin. Three screening methods were used to identify the most promising strains, including growing them in media supplemented with flaxseed oil, testing their ability to degrade triacidin in rotamine B, and fermenting them with flaxseed oil. Six strains of the genera fusarium, penicillium, and mucus were identified as having cutinase activity. Two strains, fusarium, fujikura, and penicillium chrysogenum, were found to be particularly efficient at cutting up cutin, with activities of 33.5 u slash ml and 39.4 u slash ml respectively. These results suggest that these strains could potentially be used to develop new biotechnological applications such as biofuel production or cosmetics.
