Endophytes represent a diverse domain of microorganisms with immense biotechnological potentialities. Metabolites from endophytes, especially fungi, are useful in industrial as well as pharmaceutical aspects. Here, endophytic fungal isolates of Andrographis paniculata collected from the Tapobon, Junglemahal region of West Bengal, India, have been studied for their hydrolyzing enzyme production abilities. Out of eighty-one isolates, twenty-one were positive for amylase, protease, lipase, laccase, and tannase action. Microscopic features of positive isolates revealed that the enzyme producers were Aspergillus sp., Fusarium sp., Alternaria sp., Trichoderma sp., Exerohilum sp., Nigrospora sp., Curvularia sp., Cladosporium sp., Cochliobolus sp., Tricothecium sp., Penicillium sp., Verticillium sp., and Cephalosporium sp. The amylolytic activity was remarkable in the case of endophytic Aspergillus sp. and Fusarium sp. Also, Aspergillus sp. and Alternaria sp. had proteolytic activity. Aspergillus sp., Mycelia sterilia-2, and Trichoderma sp. were potent lipase producers. Along with Exerohilum sp. endophytic Aspergillus sp. had positive laccase activity. The tannic acid degrading activity was highest for Aspergillus sp. APL11 followed by Helicosporium sp. and Fusarium sp. Tannase producing ability of Aspergillus sp. was optimized and an incubation time- 96h, incubation temperature- 29°C, initial medium pH- 6.5, carbon source- glucose, and nitrogen source- NaNO₃ exhibited a two-fold scale-up of (2.83±0.05 u mL^-1) in tannase action. These enzymes offer eco-friendly and efficient solutions across a wide range of industrial processes including food production, textile processing, and pharmaceutical synthesis. Fungal endophytes of medicinal plants act as an alternative source for hydrolysing enzymes.
