Thus, the most promising indigenous Gram +/-ve strains from the long-term contaminated sites with increased catabolic potential, enzymatic activity and metal tolerance need to be harnessed for mixed contaminant cleanups.]]> Sat 24 Mar 2018 07:14:19 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:25124 Brevundimonas diminuta were predominant whereas Clostridium and Pseudomonas species dominated for inland sites with agricultural or forestry activities. Bacillus and Enterococcus were dominant for sites close to a fertilizer plant and a sewage treatment plant, respectively. Actinobacteria species dominated at sub-alpine conditions. Results from this study indicate that microbial communities on corroding steel exposed to atmospheric conditions are the result of deposition of locally-generated aerosols. Acid-producing activity and exopolysaccharide (EPS) production was widespread and rapidly detected in microbial cultures from all the exposure sites. Sulphate-reducing bacteria were not detected in this study. These results suggest that acid production and EPS synthesis can be important mechanisms for microbial corrosion of steel under atmospheric conditions.]]> Mon 23 Sep 2019 10:59:47 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:40759 Mon 18 Jul 2022 13:54:19 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:51571 Mon 11 Sep 2023 14:37:03 AEST ]]>
