Article Abstract:
Research was conducted to examine an enzyme-linked immunofiltration assay that was developed to measure the attachment of Thiobacillus ferrooxidans on sulfide minerals. A comparison of the method with indirect and more classical bacterial cell counting methods was performed to evaluate the method that was derived from the enzyme-linked immunosorbent assay. Results provide evidence that the method may be utilized to create adhesion isotherms of T. ferrooxidans on different sulfide minerals exhibiting various physicochemical characteristics to gain insight into the mechanisms of bacterial interaction with mineral surfaces.

Article Abstract:
Some species of Pseudomonas may have potential as biological control agents. Pseudomonas brassicacearum and Pseudomonas thivervalensis were isolated from wheat field soils in South Australia and substantially reduced root lesions caused by Gaeumannomyces graminis var. tritici.

Article Abstract:
Inoculating sunflower seeds and the surrounding soil with an exopolysaccharide-producing strain of Rhizobium resulted in a significant increase in root-adhering soil mass. The bacterium also counteracted the effect of water deficit and increased nitrogen uptake by the plant.
