Abstract Fusarium dry rot is considered to be the most critical soilborne and postharvest disease that damages potato tubers worldwide when they are stored for a long time. This study was performed to demonstrate the effect of crude extract, culture filtrate, and cell suspension obtained from the bacterium Bacillus subtilis HussainT-AMU, on the net house and field. From oil-contaminated soil, through the serial dilution method, biosurfactant bacteria were isolated on nutrient agar medium. To isolate and screen the prospective biosurfactant strain, various biosurfactant screening methods were used. Standard protocols were carried out for morphological, molecular, and chemical characterization. The disease incidences… More >

Abstract An increasing number of studies provide evidence for the existence of a microbiota-gut-brain axis and its potential involvement in the development of sporadic Parkinson’s disease and other neurodegenerative conditions. The neuropathologic hallmark of Parkinson’s disease is the presence of brain intraneuronal aggregates of misfolded alpha-synuclein, known as Lewy bodies. Some gut microbiota products may trigger alpha-synuclein conformational changes in the neurons of the enteric nervous system, which can then spread to the brain in a prion-like fashion through the vagus nerve. Others may interfere with neuroinflammatory pathways and susceptibility to neurodegeneration. In this review, we assess the potential role of… More >

Abstract The aim of the present study was to isolate autochthonous microorganisms with biosurfactants capacities from the rhizospere of the cotton (Gossypium spp.), cachanilla (Pluchea sericea) and salicornia (Salicornia bigelovii) in the Mexicali valley. The biosurfactant activity and biosurfactant productions by the strains isolated from the rhizosphere of the cotton (Bs-Alg), cachanilla (Bs-Cach) and salicornia (Bs-Cach01) were determined using oil spreading technique and emulsification activity with corn, olive, soybean and diesel oils, respectively. The analysis of the 16S rRNA showed that strains Bs-Alg, Bs-Cach and Bs-Cach01 are closely related among them and with respect to all Bacillus subtilis with more than… More >
