Nitrilase gene detection and nitrile metabolism in two bacterial strains associated with waste streams in Lagos, Nigeria
Growth potentials of nitrile-metabolizing bacteria on nitriles Bacillus sp. and Corynebacterium sp. had doubling times of 12.16 and 9.46 (µ = 0.082, 0.106) on glutaronitrile (single substrate) (Table 2), while doubling times of 7.40 and 7.75 (µ = 0.135, 0.129) were recorded for the mixed culture...

| Tóm tắt: | Growth potentials of nitrile-metabolizing bacteria on nitriles
Bacillus sp. and Corynebacterium sp. had doubling times of 12.16 and 9.46 (µ = 0.082, 0.106) on glutaronitrile (single substrate) (Table 2), while doubling times of 7.40 and 7.75 (µ = 0.135, 0.129) were recorded for the mixed culture on glutaronitrile (single substrate) and mixed substrates (glutaronitrile and benzonitrile) (Table 2). Similarly, Bacillus sp. and Corynebacterium sp. had doubling times of 11.11 and 10.00 (µ = 0.090, 0.100) on benzonitrile (single substrate), while doubling times of 8.09 and 8.71 (µ = 0.124, 0.115) were recorded for the mixed culture on benzonitrile (single substrate) and mixed substrates (Table 2). The results showed that the mixed cultures of the bacterial species had better growth in each of the nitrile compounds both as single and mixed forms (Table 2). |
