| description | The diversity and resource potential of macroscopic fungi in tropical regions remain understudied. Vietnam, being in a biodiversity hotspot, has a large number of new fungal species that are of interest for biotechnology and medicine. The presence of a large number of protected areas in Vietnam creates favorable opportunities for the study and ex situ conservation of tropical biodiversity. From 2012 to 2023, 785 strains of macrofungi from National Parks of Vietnam were preserved in the LE-BIN collection, 327 of which were barcoded with the sequences deposited in the NCBI GenBank. A taxonomic analysis demonstrated that many of the preserved isolates are potentially new or poorly studied species, representing a useful resource for taxonomical studies and a search for new medicinal mushrooms. More than 180 strains were studied for the first time for growth rate and enzymatic activities. Of these, 53 strains showed high growth rate, 43—high cellulolytic activity, 73—high oxidative enzymes activity, and 27 showed high proteolytic activity, making them promising candidates for biotechnological and medical applications and opening new opportunities for sustainable biomass management, discovery of new enzymes and bioactive substances, development of new drugs and efficient plant waste treatment technologies. The results confirm the importance of the ex situ conservation of fungal diversity in tropical regions as a valuable source for scientific and commercial applications and suggest certain new active strains for biotechnological study. |
