Butachlor biodegradation potential of fungi isolated from submerged wood and surface water collected in Taal Lake, Philippines

Taal Lake in the Philippines is a hotspot of diverse organisms but also faces a great threat from toxic agrochemical contaminants. Specifically, fungi are promising bioremediation agents to degrade harmful pollutants in the environment; hence the documentation and identification of these isolates ar...

QD Chemistry Taal Lake in the Philippines is a hotspot of diverse organisms but also faces a great threat from toxic agrochemical contaminants. Specifically, fungi are promising bioremediation agents to degrade harmful pollutants in the environment; hence the documentation and identification of these isolates are crucial. This study aims to determine the occurrence of fungi from submerged woods and surface waters in Taal Lake and assess their biodegradation potential against butachlor, a widely used pesticide in the Philippines. The isolated fungi were identified by using morphological and/or molecular methods, and the occurrence of each species was recorded.
