Abstract
Biofiltration is a biotechnological process used to treat air polluted with
volatile organic compounds (VOC). Paint thinner is a commercial mixture
of VOC used in many industrial processes. In this study a microbial
consortium adapted to consume paint thinner as sole carbon and energy
source was selected. Conventional microbiological techniques were
conducted to identify Bacillus subtilis, B sphaericcus, B schleggelli, B.
brevis, Micrococcus luteus and Pseudomonas pseudoalcaligenes as
constituents of the consortium. The compatibility between support
material (rice hulls) and microbial consortium was evaluated by
microcosms experiments. Biodegradation studies were conducted in
microcosms in liquid as
