Abstract The potential of indigenously isolated bacteria from the Estância Velha stream to reduce Cr(VI) was evaluated and also the chromium contamination over the past ten years was verified in one of the most important industrial centers of Brazil, the “Brazilian Capital of Tanneries,” Estância Velha municipality in the Rio Grande do Sul State, South Brazil. Samples were collected from the Estância Velha stream at the source (P1), as well as at upstream (P2) and downstream (P3)...

Abstract In the current study, an extracellular cellulase belonging to symbiotic Bacillus subtilis Bc1 of the leopard moth is purified and characterized. The molecular mass of enzyme was 47.8 kDa using SDS-PAGE. The purified enzyme had optimum activity in temperature and pH around 60 °C and 8, respectively. The purified cellulase was introduced as a stable enzyme in a wide variety of temperature (20–80 °C) and pH (4–10) and remained active to more than 74% at 80 °C for 1 h. Moreover,...

Abstract A radio-resistant bacterium labeled as strain TMC-6 was isolated from Thal desert, Pakistan and identified through 16S rRNA gene sequencing as Bacillus indicus strain TMC-6 (MN721293). The isolate was found to be resistant to UV radiation dose of 6.780 × 103 J/m2 and showed 50% survivability to mitomycin C (6 μg/ml) and H2O2 (30 mM). The bacterium showed yellowish orange coloration when grown on tryptone yeast glucose (TGY) medium. The cellular metabolite was extracted...
