Evaluation of biocontrol properties of Streptomyces spp. isolates against phytopathogenic fungi Colletotrichum gloeosporioides and Microcyclus ulei

South American Leaf Blight (SALB) of the rubber tree, caused by Microcyclus ulei and foliar anthracnose caused by Colletotrichum gloeosporioides, are diseases that adversely affect rubber cultivation in America. Both diseases have a significant economic impact on this agricultural subsector. The aim of the present study was to evaluate the potential as biological control agents of three Streptomyces species strains,...

Endogenous fungi isolated from three locoweed species from rangeland in western China

Leguminous locoweeds cause toxicosis to grazing animals in western China and western USA. Swainsonine, a toxic alkaloid, is produced by the endophytic fungus Alternaria section Undifilum sp. living within the locoweed plants. Nothing is known of the other endogenous fungi associated with locoweed and it is unknown if the presence of Alternaria sect. Undifilum sp., a potential mutualist, in a locoweed influences the...

Microbial community structures of an offshore and near-shore oil production facilities after biocide treatment and the potential to induce souring and corrosion

Microbial communities of six samples from Escravos and Meren oil production facility in Nigeria were examined after biocide treatment using cultural and molecular approaches. Sulfate reducing bacteria (SRB) count and activity were the highest in skimmer pit samples (1N1) which was affiliated with Euryarchchaeota (44%) and Proteobacteria (39%). Treatment of Meren injection water (1N2) with biocides significantly reduced...

Microbiological quality of selected dried fruits and vegetables in Maseru, Lesotho

Food safety is a global issue, affecting food production and processing. The study assessed the microbiological quality of commercially dried fruits and home dried fruits and vegetables in Lesotho. Moisture content, pH and water activity of the fruits and vegetables were determined using standard methods. Nine different growth media were used for microbial evaluation. Moisture content and water activity were within...

Enhancement of the expression of defense genes in tomato against Ralstonia solanacearum by N-octanoyl-L-homoserine lactone

Many Gram-negative bacteria use N-acyl-homoserine lactone (AHLs) as quorum sensing (QS) signalling molecules to monitor their population density and to regulate gene expression in a density dependent manner. Recently, it has been shown that AHLs are detected by the plants and they trigger plant defense responses. In this study, N-octanoyl-L-homoserine lactone (C8-HSL) has been used as resistant inducer against bacterial...

Microbiological quality of raw vegetables and ready to eat products sold in Abidjan (Côte d’Ivoire) markets

Vegetables are usually consumed raw. This implied best hygienic conditions from the harvest to the processing because of the gastro-enteritis that they could provoke. This study was conducted with the aim to appreciate microbiological quality of raw tomatoes, endives and ready-to-eat products sold in markets. Samples were taken randomly in two markets of Abidjan. A microbiological analysis was done in order to identify...
