Eleven pure strains of sulfate-reducing bacteria have been isolated from lab-scale bioreactors or disposal sites, all featuring relatively high concentrations of sulfate, and from natural environments in order to produce sulfide from gypsum using hydrogen as energy source. The properties of the eleven strains have been investigated and compared to these of three collection strains i.e. Desulfovibrio desulfuricans and vulgaris and Desulfotomaculum orientis. Particular attention was paid to the absolute and relative sulfide production rate and to the hydrogen sulfide inhibition level. By comparison to the collection strains, a 75 % higher production rate and a hydrogen sulfide inhibition level about twice higher i.e. 25.1 mM have been achieved with strains isolated from sulfate-rich environments. The strain selection, particularly from sulfate-rich environments, should be considered as an optimization factor for the sulfate reduction processes. [less ▲]

Pyoverdins are chromopeptides produced by the so-called fluorescent group of the bacterial genus Pseudomonas. Species or even strain specific they differ in the composition of their peptide chains. For classification purposes it is of importance to get fast information regarding the nature of the latter. For two new representatives from hydrolysis results and especially from an analysis of the data obtained from electrospray ionization (ESI) and fast atom bombardement (fAn) mass spectrometry measurements the amino acid sequences can be suggested as Asp-BuOHOrn-Dab-aThr-Gly-Ser-Ser-OHAsp-aThr (Pseudomonas putida BTP16) and Ser-SerFoOHOrn-Ser-Ser-Ser-FoOHOrn-Lys-Lys (Pseudomolnas fluorescens BTP7).

To study the effect of lipid and peptide structural attributes of Bacillus subtilis lipopeptides on their foaming properties, the formation, stability, and appearance of foams prepared with surfactins (C13 C15) and iturins A (C14 C17) were characterized. The density and stability of lipopeptide foams depend on both the alkyl chain hydrophobic character and peptide molecular intrinsic properties. A lipidic chain length of 14 carbon atoms provides lipopeptides with the best foaming properties in terms of foam density and liquid stability in foams. Increases in alkyl chain length above 15 carbon atoms result in a drastic decrease of iturin A foam density. With the same alkyl chain, surfactin produces denser foam whereas iturin A exhibits better foaming stability. These results demonstrate the importance of the peptide structural attributes of B. subtilis on their foaming properties. [less ▲]
