The ability of some bacteria and filamentous fungi to degrade aniline and its derivatives has been reported in literature. This report is the first one concerning assimilation of aniline by Candida methanosorbosa BP-6 strain was isolated from wastewater dye factory by enrichement technique. Activity of this strain to degradation of aniline was compared with four bacterial strains: BD1, BZB1, BR 1, and PKN 7, isolated from the same environment and bacteria Bacillus subtilis IBT C-3 derived from the collection of Institute of Technical Biochemistry P?. Among the six tested strains capable to assimilate aniline, the most succesfull was Candida methanosorbosa BP-6 which quickly grows in the presence of high concentration of aniline (1-4%) and can degrade this substrate in the yield of 54-63%.

The embodiment of subtilisin from Bacillus subtilis IBTC-3 in triacetylocellulose (TAC) fibre was studied. The fibre preparation of proteolytic activity 51.3 AmU/g was obtained with 16.6% of yield. The properties of subtilisin embedded in TAC fibre were investigated. The preparation showed optimal proteolytic activity at pH 9 and temperature 65-70C. It was stable in a wider range of pH and temperature than the native subtilisin. The KM value for haemoglobin was 2.6 ? 10-3 M. The TAC-fibre biocatalyst, in the fixed bed column, was successfully applied for hydrolysis of casein.
