The biotechnological relevance of ligninolytic organisms remains topical and may remain so in the foreseeable future. The enzyme battery produced by ligninolytic bacteria, including Bacillus species, has shown immense industrial significance. Consequently, peroxidases produced by newly isolated ligninolytic Bacillus strains from the marsh and grassland in Hogsback forest reserve of the Eastern Cape Province of South Africa were evaluated for decolourization of anthraquinone (Remazol Brilliant Blue R-RBBR) and azo (Congo Red-CR) dyes. Maximum dye decolourization was observed with the peroxidase from Bacillus sp. NWODO-3: CR (69.89±2.64 %) and RBBR (72.12±0.38 %). Dye decolourization readings for peroxidases from the other Bacillus strains were CR: 55.06±5.48 %, RBBR: 70.45±0.0 % (Bacillus sp. MABINYA-1), 42.62±5.55 % and 42.42±4.82 % against CR for Bacillus sp. MABINYA-2 and Bacillus sp. FALADE-1, respectively. RBBR was less susceptible to the attack by crude peroxidase produced by Bacillus sp. MABINYA-2 and Bacillus sp. FALADE-1 as the dye decolourization activities observed were 4.91±0.36 % and 1.19±0.0 %, respectively. These results suggest the industrial relevance of peroxidases from the new ligninolytic Bacillus strains in bioremediation.
