Slug control is a major concern in crop fields because these mollusks consume and damage plants that are destined for human consumption and ornamentation. The grey field slug Deroceras reticulatum (Müller, 1774) is one of the most commonly occurring mollusks with agronomic importance, consuming up to 80% of the leaf surface of raps and other crops. The major difficulty in slug control is that the main products used for this purpose can also endanger non-target animals, such as pets and birds. New methods of control that are naturally based and environmental friendly are urgently required, both for the... |

| Reduced volatile sulphur compounds generate an impact on the environment, because of the bad smell and its low odour threshold. Compared with the existing physicochemical technologies for their elimination, biotrickling filters are an economically and environmentally sustainable alternative. Usually mixed cultures of microorganisms are used for inoculating biotrickling filters, in this case a pure culture of Thiobacillus thioparus is used for generating a biofilm, allowing to measure its capacity for the oxidation of four volatile reduced sulphur compounds: hydrogen sulphide, dimethyl sulphide, methyl mercaptan and dimethyl disulphide, using a residence time of 0.033 hrs. The viable cells of the biofilm were quantified by epifluorescence microscopy,... |
