“…In rather large amounts (0.01% and higher) copper ions can have a fungicidal effect. However, in small amounts a respiratory shock occurs in cells resulting in the slowdown of cell development, but not in the loss of cell viability (Rodin et al 2005). After almost 4 months of storage at +30°C (the equivalent of approximately 1 year of storage at +20°C) all but one of the samples at pH 3.0 and most of the samples at pH 4.0 with starch and copper sulfate added maintained a high level of competitiveness.…”

The formulation of microbial biomass represents a critical step in advancing the commercial development of prospective biological control products. Trichoderma asperellum has demonstrated biological control capability against Fusarium head blight. In the present studies, Trichoderma asperellum was grown in liquid media of differing composition. The effect of various amendments on the preservation of the viability and competitiveness, in vitro, of fungal mycelium and spores in a liquid paste was determined. The amendments with greatest effect were the addition of starch as a food base, reduction of metabolic activity by lowering the pH of the biomass paste and the addition of small amounts of copper. Oxygen availability was also shown to be important in maintaining biomass viability and competitiveness. Optimization of these factors produces a biomass paste formulation of T. asperellum that remains active, in vitro, for at least 6 months at room temperature.

“…A simplified model of colony growth has been presented (Rodin et al, 2005). According to this model, during growth, a colony passes successively through exponential and linear phases of growth, with the exponential phase persisting unless the concentration of nutritious substrates becomes limited.…”

“…The method has been used to determine the synergistic effects of copper sulfate and kathon, (2-N-octyl-4-isothiazolin-3-one) on S. marcescens (Rodin et al, 2005). Amino alcohols are not biocides themselves, but they enhance the performance of a wide range of biocides, which are used in water-based fluids (Coburn et al, 2010).…”

“…The effect of biocides on microbial cells is determined by several methods [3][4][5], whereas MIC is determined by a single microbiological method [6,7]. This method involves dilutions of biocidal substances, inoculation of cells at equal concentrations (most often, 10 6 -10 7 cells/ml), and determination of the dilution at which inoculation into selective nutritive media produces no colony-forming units (cfu).…”

By using a bioluminescence ATP assay, we have determined the minimal concentrations of some biocorrosion inhibitors (Kathon, Khazar, VFIKS-82, Nitro-1, Caspii-2, and Caspii-4) suppressing most common microbial corrosion inducers: Desulfovibrio desulfuricans , Desulfovibrio vulgaris , Pseudomonas putida , Pseudomonas fluorescens , and Acidithiobacillus ferrooxidans . The cell titers determined by the bioluminescence method, including not only fissiparous cells but also their dormant living counterparts, are two-to sixfold greater than the values determined microbiologically. It is shown that the bioluminescence method can be applied to determination of cell titers in samples of oil-field waters in the presence of iron ions (up to 260 mM) and iron sulfide (to 186 mg/l) and in the absence or presence of biocidal corrosion inhibitors.
