Forty-nine fungal isolates from mangoves in Calatagan, Batangas and Pagbilao, Quezon were screened for their enzymatic properties and identified. All the isolates showed gelatinase activity, seven with tyrosinase activity, and one with peroxidase activity. None produced lipase, caseinase/proteinase and amylase, tyrosinase producers were identified as Aspergillus fumigatus, A. niger, Fusarium poae, F. avenaceum, Penicillium citrinum, and P. funiculosum while the perodidase producer was F. solani. The eight fungal isolates with either tyrosinase or peroxidase activity were directly or indirectly involved in lignin modification. Quantification of the enzymatic activities must be determined to further establish their potential usefulness for lignin degradation
