Bioproduction of lipopeptides by dye decolourising bacteria and its roles in textile dye decolourisation

Textile dyes are recalcitrant molecules and contain a high level of chemicals and colour which poses a serious challenge to surrounding environments. Therefore, this study aims to determine the ability of isolated bacteria in producing a biosurfactant and investigate their synergistic action on deco...
