Although, synthetic dyes have toxic effects on to environment, are very important for coloration of large number materials and lead increasing concerns about color removal worldwide. Immobilization microorganisms is one the promising techniques biological treatment wastewater with many advantages industrial usage. This study aimed determine efficiency immobilized four different Bacillus species...

The presence of fungicides in the natural environment, either resulting from deliberate actions or not, has become a serious threat to many ecosystems, including soil. This can be prevented by taking appropriate measures to clear the environment of organic contamination, including fungicides. Therefore, a study was conducted aimed at determining the effect of bioaugmentation of soil exposed to ...

Seven Bacillus spp. were exposed to simulations of Mars-normal UV fluence rates in order to study the effects of UV irradiation on microbial survival. A UV illumination system was calibrated to deliver 9.78 W m−2 (35.2 kJ m−2 h−1) of UVC + UVB irradiation (200–320 nm) to microbial samples, thus creating a clear-sky simulation (0.5 optical depth) of equatorial Mars. The Bacillus spp. studied wer...
