Abstract
Biosurfactants have many advantages outside chemical one, led for application it through different sectors. So, the present study aimed for improving the bioremediation technology of contaminated wastewater using biosurfactants produced by novel bacillus isolates. In this regard, Bacillus thuringiensis and Bacillus toyonensis strains were obtained as most producing isolates of highly active biosurfactants. The optimized conditions for high biosurfactants yield production were established. Also, the stability of the produced biosurfactants at various conditions, pH, temperature and salinity was studied. The biosurfactant has been reported up to 120 °C, pH 12 and 10% of NaCl. The identified biosurfactants, decanoic acid and oleamide were applied for wastewater remediation from oil residues and pathogens contamination. The biosurfactant was had high antibacterial activity compared with references antimicrobial drugs, as well as it is enhanced bioremediation technology for petroleum oil residues contaminating sites. Thus, we can say, these biosurfactants could achieve the objectives of sustainable development.
Highlights
Biosurfactants have a great potential due to their advantages over synthetic one especially in the sectors of environment (Ashraf et al, 2017; Barakat et al, 2017), food industry (Nitschke and Silva, 2018), agriculture (Sachdev and Cameotra, 2013), biomedical products (Singh and Cameotra, 2004; Saha et al, 2018) and nanotechnology (Singh et al, 2017)
Biosurfactants have noted as microbial products by high values, that have become an important product for biotechnology application in medical and industry (Nitschke and costa, 2007; Makkar et al, 2011)
Fourteen samples were collected from oil-contaminated habitats: soil, water and wastewater to isolate bacteria, which are supposed to produce biosurfactant
Summary
Biosurfactants have a great potential due to their advantages over synthetic one especially in the sectors of environment (Ashraf et al, 2017; Barakat et al, 2017), food industry (Nitschke and Silva, 2018), agriculture (Sachdev and Cameotra, 2013), biomedical products (Singh and Cameotra, 2004; Saha et al, 2018) and nanotechnology (Singh et al, 2017). It may be produced inside the cells (intracellular) or as extracellular agent (Antoniou et al, 2015)
