    In this study we have assessed the capacity of five fungal and two bacterial species to biodegrade glass fiber acrylic composite filters which are utilized in air conditioners. The strains used were Trichoderma harzianum (2 strains), Trichoderma koningii, Penicillium spp., Aspergillus niger, Pseudomonas aeruginosa and Pseudomonas fluorescens. Pre-sterilized filters were incubated in solid or liquid media at 30 C for 21 days. Biodegradability was monitored by evaluating microbial colonization, increase in biomass and weight loss of filters coupons. Among the species under investigation, the two strains of T harzianum (MYA198 and BCC5828) showed the best biodegradability performance and were used to analyse total carbon and esterase activity. Our results clearly indicate that cells grown in the presence of shredded filters display a hydrolytic activity and lead to a consistent removal of the organic portion of the tested filters. This study suggests that a solid state fermentation process in suitable bioreactors based on T. harzianum species could be a suitable approach to acrylic composite filter biodegradation
