lactic acid bacteria (lab) are gram positive and non- spore forming bacteria that can produce some special substances for growth inhibition of pathogenic, non-pathogenic and food spoilage bacteria. the aim of this study was to determine the inhibitory effects of lactobacillus acidophilus ptcc1643 (dsm 20079) and lactobacillus plantarum ptcc 1058 (atcc 8014) cultural supernatants against urinary...

One hundred seventy-seven actinomycetes strains were isolated from soils collected from fruit orchards in Thailand. All were tested for antibacterial activity against seven pathogenic bacteria using co-cultivation methods. Forty strains (22.6%) were active against at least one indicator bacteria. Twenty-seven strains (15.3%) inhibited only gram-positive bacteria, four strains (2.3%) inhibited o...

During the course of our screening program for new antibiotics, Streptomyces sp. 80432 isolated from a soil sample was found to produce a water-soluble antibiotic. This antibiotic, named minimycin, showed not only inhibitory activity against Grampositive and Gram-negative bacteria, but also antitumor activity. Isolation and purification by a chromatography gave a colorless crystalline substance...

Potentially nodulating Leguminosae species had high density and biomass in young stands of forests Northeast Brazil, except a dry forest on low-fertility soil. species, especially potentially ones, appear to be important components tropical secondary forests, although information is still scarce concerning their contributions richness under different environmental conditions. To evaluate the co...

Abstract Introduction: The aim of this study was to identify the antibacterial components in the ethanol extraction of Aloe vera against four clinically frequent pathogenic  bacteria. Materials and Methods: In this in-vitro study, Aloe vera extraction was prepared by dissolving 500 grams of the powder in 5L of 95% ethanol. The antibacterial activity of the extraction against Staphylococcus a...

Sophora tomentosa is a pantropical legume species with potential for recovery of areas degraded by salinization, and for stabilization of sand dunes. However, few studies on this species have been carried out, and none regarding its symbiotic relationship with beneficial soil microorganisms. Therefore, this study aimed to evaluate the diversity of nitrogen-fixing bacteria isolated from nodules ...
