Abstract

Fifty-one fungi from different genera and strains were checked in plate to determine lipase activity in protein precipitates from their autolysed cultures. Each of them was then analysed at 3.5, 6.5 and 9.2 pH units and, as a consequence, basic lipases with high activity at 9.2 pH were found after 1 h of incubation. Only 25% of the studied fungi showed this lipase activity, among them the best producers were fungi from genus Fusarium (47% of fungi had lipase activity). In addition to lipase activity, Fusaria showed a low hydrolytic activity on cutin and suberin. The genus Aspergillus produced lipase and cutinase activity to a similar extent. Aspergillus nidulans 2544 also showed suberinase activity in a considerable amount. Penicillium species had very low activities. Other species and strains from genus Trichoderma, order Mucorales and class Basidiomycetes, did not show lipase activity in their degradative processes.
