“…In the Asia Pacific, especially the Philippines, current studies about marine fungi are mostly focused on substrates other than macroalgae, i.e. mangroves, marine sediments, seagrass and seawater (Yao et al 2009, Besitulo et al 2010, Ramirez et al 2010, Torres et al 2011, Jones et al 2013, Torres & dela Cruz 2013, Su et al 2014, Notarte et al 2017, although an earlier study reported the potential role of marine fungi in ice-ice disease formation among cultivated seaweeds (Solis et al 2010). Additional research focusing solely on algicolous fungi in the Philippines is highly advantageous for the discovery of novel metabolites since both the area and the substrate has not yet been fully explored.…”

Lavadia MGB, Dagamac NHA, dela Cruz TE 2017 -Diversity and biofilm inhibition activities of algicolous fungi collected from two remote islands of the Philippine archipelago. Current Research in Environmental & Applied Mycology 7(4), 309-321, Doi 10.5943/cream/7/4/8 AbstractAlgicolous fungi are valued for their pharmaceutically and agrochemically useful secondary metabolites. However, very few studies on algicolous fungi have been carried out in the Asia Pacific region, particularly in the Philippines, in spite of the country's rich macroalgal flora. In this study, a total of 212 algicolous fungi belonging to 29 morphospecies were recorded from seaweeds (macroalgae) collected from Potipot Island and Lubang Island, northern Philippines. These fungi were identified as species of Aspergillus, Alternaria, Chaetomium, Cladosporium, Colletotrichum, Nigrospora, Pestalotia, Penicillium, and Trichoderma. Diversity assessment among collection sites and among algal groups was determined. Lubang Island registered higher species richness than Potipot Island, while brown algae had the highest compared to red and green algae. Species diversity measured by Shannon Index and Simpson Index showed no significant difference between the two study sites, while brown algae had the highest species diversity among the algal groups. Comparison of communities shows that the morphospecies clustered more based on the site they were collected, and not based on their algal host. Communities have more similarities between those isolated from the smaller island of Potipot than in Lubang, which may show that proximity and anthropogenic activity might affect the distribution of fungal communities. Extracts of the AF isolates were used against biofilm-forming S. aureus to determine whether AF can inhibit biofilm formation. The results of the assay showed that algicolous fungi extracts can successfully reduce biofilm formation as much as 99%.
