“…The multiple regression analysis served to analyze the obtained data in order to acquire an empirical model that could relate the independent variables to the measured response. Thus, the following quadratic equation could explain the behavior of the system: The multi-linear regression method served to estimate the model coefficients using the statistical software package (Nemrod-W by LPRAI Marseilles, France) as described in our previous works (Mnif et al 2021b). The statistical significance of the model was evaluated on the basis of F-test with unequal variance (p , 0.05).…”

Aiming at the potential application of lipopeptide biosurfactant (BioS) in bioremediation, we studied its production by a novel, isolated strain of Bacillus sp. MI27. Using the experimental design methodology, a sucrose-based medium composed of 2% sucrose, 0.27% Na2HPO4, 0.2% ammonium sulfate, 0.02% NaCl, 0.02% CaCl2, 0.02% MgSO4, 0.001% MnSO4, 0.06% KH2PO4, 0.005% FeSO4 and 0.005% ZnSO4 was optimized. With this composition, strain MI27 produces 1.4 g/L with maximum surface tension (ST) reduction of 23 mN/m and a dispersion diameter of around 10 cm. Emulsifying and foaming activities have been also confirmed. The critical micelle concentration (CMC) value of about 120 mg/L with a maximal decrease of ST of 23 mN/m with a maximum dispersion and an emulsification index (EI) of about 12 cm and 45% at 1,000 mg/L. Moreover, the foaming capacity is about 80% at 1,000 mg/L stable over 1 h of incubation. Additionally, we studied the effect of different values of pH, temperature and salinities on MI27 BioS activity and stability. Obtained results showed interesting surface activities at extreme physicochemical conditions, especially at acidic and alkaline pH values, high and low temperatures and higher salinities. All these characteristics enable the possible application of BioS in water treatment biotechnology under diverse environmental conditions.

Heavy metals (HMs) pollute the environment on a global scale and have different harmful effect on ecosystem. Outstripping accumulation of diverse toxic HMs in soils has altered the diversity, structure and function of microflora, degraded soils, reduces growth and yield of plant, and entered the food chain. HM treatment is necessary for maintaining the agricultural soil health. Many procedures and approaches have been used to recover contaminated soils in recent time, however, most of them were too pricey not environmentally friendly, and negatively affected soil properties. Usage of microbes was found as cost affective and ecofriendly approach for bioremediation of HMs. Microbes increased sustainability in agriculture soil health, which is essential to uninterrupted plant growth or improvement in stress full condition through mechanism likes productions phytohormones, organic acids, biosurfactants, exopolymers, antioxidant enzymes; and solubilization of phosphorus. It is well known that plant growth-promoting microbes enhance crop productivity and plant resistance to HM stress. In this following review, deep insight have has provided on mechanism of alleviation of HM stress by microbes and enhancement of plant growth promotion.

The application of halophilic biosurfactant-producing bacteria to remove the pollutants from textile effluent was investigated in the current study. Staphylococcus sciuri subsp. rodentium strain SE I isolated from Sambhar Salt Lake, Rajasthan showed the highest emulsification activity of 65 � 1.2 % after 96 h of incubation with a yield of 0.189 g/l of biosurfactant. The surface tension was reduced to 46.23 mN/m � 0.46 after 72 h at pH 7.0. The presence of non-ribosomal protein sequences gave a hint of the presence of surfactin-type lipopeptide biosurfactant and Copper Translocating P-type ATPase enzyme sequences indicat-ing its presence can confer resistance against heavy metals. Strain SE I showed the potential to remove heavy metals from textile effluent viz. 67 % of Cd, 64 % of Pb, 59 % of Cu, 50 % of, Cr, and 33 % of Ni after 7 days of treatment as well exhibited decolorization of dyes ranging from 61 % � 0.15 to 95 % � 1.03, respectively. Based on the research findings, it is reasonable to conclude that surfactin biosurfactant extracted from S. sciuri subsp. rodentium strain SE I can be an alternative biosorbent and function as a bioremediation agent.
