The histidine kinase slnCl1 of Colletotrichum lindemuthianum as a pathogenicity factor against Phaseolus vulgaris L.

Colletotrichum lindemuthianum, the causal agent of anthracnose, is responsible for significant damage in the common bean (Phaseolus vulgaris L.). Unraveling the genetic mechanisms involved in the plant/pathogen interaction is a powerful approach for devising efficient methods to control this disease.

Water quality comparison between a supply network and household reservoirs in one of the oldest cities in Brazil.

Water is an essential good for human life. This study aimed to verify the effects of household reservoirs on the physicochemical and microbiological characteristics of water in the municipality of São Mateus, Brazil, founded on 21 September 1544. Samples were collected in 83 residences, two samples per residence, one from the supply network and another from the household reservoir, making a total of 166 samples.

Bovicin HC5 and nisin reduce Staphylococcus aureus adhesion to polystyrene and change the hydrophobicity profile and Gibbs free energy of adhesion.

Staphylococcus aureus is an opportunistic pathogen often multidrug-resistant that not only causes a variety of human diseases, but also is able to survive on biotic and abiotic surfaces through biofilm communities. The best way to inhibit biofilm establishment is to prevent cell adhesion. In the present study, subinhibitory concentrations of the bacteriocins bovicin HC5 and nisin were tested for their capability to interfere with the adhesion of S.

Genome organization and assessment of high copy number and increased expression of pectinolytic genes from Penicillium griseoroseum: a potential heterologous system for protein production.

The fungus Penicillium griseoroseum has the potential for application on an industrial scale as a host for the production of homologous and heterologous proteins, mainly because it does not produce some mycotoxins or secrete proteases under the growth conditions for pectinase production. However, for the fungus to be used effectively as an expression heterologous system, an understanding of the organization of its genome, as well as the mechanisms of gene expression and protein production, is required. In the present study, the size of the P.
