The microbiota of cork and yellow stain as a model for a new route for the synthesis of chlorophenols and chloroanisoles from the microbial degradation of suberin and/or lignin.

Article Synopsis
- Cork is primarily used for wine bottle stoppers, but it can contain 2,4,6-trichloroanisole, which causes a musty odor that negatively affects wine quality and leads to financial losses.
- The presence of yellow stain in cork indicates a degradation linked to higher microbial populations, particularly filamentous fungi that break down lignin, and this microbiota contributes to the formation of chlorophenols and chloroanisoles.
- Research identified specific fungal and bacterial species associated with yellow stain and demonstrated that certain strains can convert p-hydroxybenzoate into phenol, which can then be chlorinated, potentially leading to the development of 2,4,6-trichlorophenol.
Most of the phosphorus incorporated into agricultural soils through the use of fertilizers precipitates in the form of insoluble salts that are incapable of being used by plants. This insoluble phosphorus present in large quantities in soil forms the well-known "phosphorus legacy". The solubilization of this "phosphorus legacy" has become a goal of great agronomic importance, and the use of phosphate-solubilizing bacteria would be a useful tool for this purpose.

The goal of this study was to evaluate the effectiveness and applicability of protein and phosphorus separation processes, namely microfiltration, ultrafiltration and flocculation, using protein-rich process waters with low (LS) and high (HS) salt content from the processing of salted cod (Gadus morhua). The application of different flocculants (chitosan lactate and Levasil RD442) were evaluated at different concentrations and maturation periods (0, 1 or 3 h).

The causal agent of this disease is , a pathogen that is difficult to control with conventional methods. Therefore, there is a need to explore alternative strategies for the management of Verticillium wilt.
View Article and Find Full Text PDFSulfur oxidation stands as a pivotal process within the Earth's sulfur cycle, in which species emerge as skillful sulfur-oxidizing bacteria. They are able to efficiently oxidize several reduced inorganic sulfur compounds (RISCs) under extreme conditions for their autotrophic growth. This unique characteristic has made these bacteria a useful tool in bioleaching and biological desulfurization applications.
