Biological treatments will progressively play a key role in the epuration process. Indeed, they show different advantages like reaction specificity, multiple degradation potentialities and efficiency at very low concentrations of pollutants. Two approaches can be considered for developing biological processes of epuration : addition of bioactivators for improving endogenous microorganisms capabilities or introduction of microorganism starters for accelerating the epuration process. These two ways need as prerequisite a basic knowledge of the metabolic pathways for specific compound degradation and of microbial ecology [less ▲]

Foaming properties of surfactin were investigated and compared to those of sodium dodecyl sulfate (SDS) and bovine serum albumin (BSA). Foams were formed by a bubbling technique. Evolution of the foam volume and the liquid in the foam was monitored with optical and conductimetric methods to characterize foam formation and stability. Excellent foaming properties of surfactin were shown by its higher ability to form and stabilize the foam at a concentration as low as 0.05 mg/mL, in comparison with SDS and BSA. Surfactin produced a foam with intermediate maximum density and stabilized the liquid in foam, as well as BSA. [less ▲]

Bacillus subtilis produces three types of lipopeptides: Iturins, Fengycins, and Surfactins. These amphiphilic molecules influence the volumetric oxygen transfer (K(L)a) like chemical surfactant. K(L)a values were from two- to fivefold lower when both Iturin A and Surfactin S1 were coproduced, and from 0.57- to 0.8-fold lower when only Iturin A was produced. The addition of an oxygen vector (n-Dodecane) during fermentation increased K(L)a values (7.5-fold) and biomass production (twofold), and decreased Iturin A and Surfactin S1 production. However, at high stirring conditions and in the presence of n-Dodecane, Iturin A production was improved. [less ▲]

Biological sulfate reduction was investigated at the bench and pilot scales in order to determine optimum culture conditions. Efficient strains of sulfate-reducing bacteria (SRB) were selected by classical microbiological methods and by mutagenesis. Improvement factors, including stripping, scale-up, sulfate,and organic substrate concentrations, have been studied in batch bioreactors. Two types of pilot-scale bioreactors have been adopted, the first being completely mixed with free cells and the second having two stages with immobilized cells on a fixed bed. An overall bioconversion capacity of 11 kg/m(3) . d of gypsum and 1.2 kg/m(3) . d of dissolved organic carbon has been achieved in the two-stage bioreactor. [less ▲]
