Five lignicolous mangrove fungi (Hypoxlon oceanicum, Julella avicenniae, Lignincola laevis, Savoryella lignicola and Trematosphaeria mangrovei) produced extracellular endoglucanase, cellobiohydrolase and β-glucosidase when cultivated under static conditions in a defined liquid growth medium. Agitation of cultures completely repressed enzyme production. Cellulase production by H. oceanicum was 2–5 fold higher compared to other strains. Increasing salinity generally resulted in reduced enzyme production although responses varied, but J. avicenniae appeared relatively unaffected by salinity within the range 0–3·4%.
