Fungal diversity associated with Goa's tarballs: Insights from ITS region amplicon sequencing.

This study explores the fungal diversity associated with tarballs, weathered crude oil deposits, on Goa's tourist beaches. Despite tarball pollution being a longstanding issue in Goa state in India, comprehensive studies on associated fungi are scarce. Our research based on amplicon sequence analysis of fungal ITS region fills this gap, revealing a dominance of Aspergillus, particularly Aspergillus penicillioides, associated with tarballs from Vagator and Morjim beaches. Other notable species, including Aspergillus sydowii, Aspergillus carbonarius, and Trichoderma species, were identified, all with potential public health and ecosystem implications. A FUNGuild analysis was conducted to investigate the potential ecological roles of these fungi, revealing a diverse range of roles, including nutrient cycling, disease propagation, and symbiotic relationships. The study underscores the need for further research and monitoring, given the potential health risks and contribution of tarball-associated fungi to the bioremediation of crude oil-contaminated beaches.
