✦ Synopsis
The ability of a mixed natural microbial population, collected in an aerated lagoon treating Fluff pulp effluent and Streptomyces viridosporus strain T7A. to degrade lignosulphonate was evaluated. S. viridosporus growing in a mineral medium containing glycerol (7 g/l) and lignosulphonate (1 gil) allowed 20% of lignosulphonate to be degraded after 18 days of incubation. A culture of the mixed population on culture medium after S.viridosporus growth was unable to degrade lignosulphonate products. Moreover, antagonism between S. viridosporus and the mixed population or between S.viridosporus and the isolated strains from this population was observed. The enhancement of lignosulphonate biodegradation by naturally occumng microorganisms in association with S. viridosporus (bioaugmentation strategy) seems to be difficult.
