Jarosite occurs naturally in acid sulphate soils and is a common feature of streams impacted by acid mine drainage (AMD). Biological reduction of iron-sulphate minerals, such as jarosite, has the potential to contribute to the natural attenuation of acid mine drainage sites. The reduction of different jarosites (including minerals containing precious and toxic metals) by a natural bacterial/microbial consortium was examined in this study. Jarosites was used as a sole terminal electron acceptor via the reductive dissolution of Fe(III) minerals. The production of Fe(II) and the presence of sulphate-reducing bacteria in the consortium lead to the precipitation of metal sulphides immobilizing toxic heavy metals. Microbial attachment and biofilm formation of minerals have a great impact on the production and transformation of minerals and can influence the mobility of metals. After the adaptation to different jarosites, a unique specie was found: Desulfosporosinus orientis. Desulfosporosinus species are sulphate-reducing bacteria and can be found in sulphate-rich heavy metal-polluted environments, such as acid mine/rock drainage sites, being responsible for the sulphides formation. D. orientis is an obligate anaerobic microorganism and is able to reduce Fe(III) D. orientis is an obligate anaerobic microorganism and is able to reduce Fe(III). Confocal laser scanning microscopy and fluorescent lectin-binding analyses (FLBA) were used to study the arrangement and composition of the exopolysaccharides/glycoconjugates in biofilms indicating the presence of mannose, glucose, and N-acetylglucosamine residues. This study provides insights to understand the processes leading to the mobility or retention of metals in mine waste and industrial landfill environments.

The major objective of this project is to achieve the direct microbiological conversion of cellulosic biomass to liquid fuel, ethanol. Within the scope of this objective, it is also the intent to maximize the conversion efficiency of ethanol production from biomass. This can be achieved through the effective utilization of both the cellulosic (six-carbon sugar) and hemicellulosic (five-carbon sugar) fractions in biomass. The degradation of cellulosic biomass is achieved through the use of a thermophilic and anaerobic bacterium, Clostridium thermocellum . This microorganism is unique in that it is able to hydrolyse both the cellulosic and hemicellulosic fractions of biomass but, unfortunately, it is not able to metabolize the pentoses. Therefore, to achieve total utilization of biomass, a second thermophilic and anaerobic microorganism, Clostridium thermosaccharolyticum , has been under study owing to its ability to convert pentoses to ethanol. Mutation, selection and adaption programmes have yielded ethanol tolerant strains of both organisms. A fermentation process using mutant strains of the anaerobic, thermophilic bacteria Clostridium thermocellum and Clostridium thermosaccharolyticum has been investigated for the direct production of ethanol from agricultural cellulosics. Through strain improvements for increased ethanol tolerance and catabolite selectivity, alcohol yields of 85% of the theoretical maximum have been obtained from solka floc with mixed culture. The method of isolation and the performance of these improved strains on both refined cellulosics and a realistic biomass, corn [maize] stover, is presented in detail.
