Última Antagonistic properties of some microorganisms isolated from Brazilian tropical savannah plants against Staphylococcus coagulase-positive strain J. Venom. Anim. Toxins incl. Trop. Dis. Ratti,R. P.; Serrano,N. F. G.; Hokka,C. O.; Sousa,C. P.. Endophytic microorganisms are relatively unstudied as potential sources of novel natural products for medical and commercial exploitation. The aim of this work was to investigate some Brazilian tropical savannah trees Cassia leptophylla and Prunus spp. in order to isolate the endophytic microorganisms associated with these plants. The samples were disinfected to eliminate the epiphytic population. Colonies were diluted and displayed as drops in media and growing colonies were inactivated. Staphylococcus coagulase-positive strain was used as indicator microorganism and subjected to the antibioses test. Data showed that the microorganisms isolated from Cassia leptophylla had no inhibition against Staphylococcus. On the other hand, microorganisms isolated...

The antimicrobial activity of chitosan and water soluble interpolyelectrolyte complexes of poly(acrylic acid)-chitosan was studied. Chitosans of two different molecular weights were tested at different concentration for 0.5 to 5 g·L-1 as antimicrobial agents against P. aeruginosa and P. oleovorans. In both cases, the best microbial inhibition was obtained with the concentration of 5 g·L-1. However, the interpolyelectrolyte complexes of poly(acrylic acid)-chitosan with composition φ =2 produced higher antibacterial activity than the two chitosans at the concentration of 0.5 g·L-1. The NPEC2 complex was more effective than chitosans. This could be attributed to the number of moles of the amino groups of chitosan and the carboxylic acid groups of the...

Amphibians respond to microbial infection through cellular and humoral defense mechanisms such as antimicrobial protein secretion. Most humoral defense proteins are synthetized in the skin. In this study we isolated two b-galactoside-binding lectins with molecular weights of 50 and 56 KDa from the skin of Bufo arenarum. These lectins have significant hemagglutination activity against trypsinized rabbit erythrocytes, which was inhibited by galactose-containing saccharides. They are water-soluble and independent of the presence of calcium. The antimicrobial analysis for each lectin was performed. At mmolar concentration lectins show strong bacteriostatic activity against Gram negative bacteria (Escherichia coli K12 4100 and wild strains of Escherichia coli...

The antibacterial activity of 35 isolates of Lentinula edodes, a shiitake mushroom, against Bacillus subtilis was evaluated by diffusion technique in agar with a semi-solid overlay. All isolates inhibited B. subtilis and the isolate Le1 promoted the formation of the largest inhibition zone. L. edodes Le1 also presented antibacterial activity against foodborne pathogens and food contaminant bacteria, particularly Gram-positive species. The antibacterial activity of the culture filtrate after 18-25 days of cultivation of L. edodes in broth at 25ºC was high. The inhibitory activity was observed only in the organic layer when the culture filtrate was partitioned between ethyl acetate and water, suggesting that the inhibitory substances have low polarity.
