It has been demonstrated that gramicidin S inhibits the outgrowth of spores of the producer-organism Bacillus brevis Nagano (Nandi & Seddon, 1978). Once again we have used the antibiotic-negative mutants E-I and BI-9 (supplied by Professor Y. Saito) in an attempt to relate control by gramicidin S over outgrowth to respiration, RNA synthesis and protein synthesis of the spores. Spores were prepa...

The surface chemical composition of whole cells and isolated cell walls of four coryneform bacteria and of a Bacillus brevis strain has been determined by X-ray photoelectron spectroscopy (XPS). The XPS data were converted into concentrations of model compounds: peptides, polysaccharides, and hydrocarbonlike compounds. The composition of the surface of B. brevis differed markedly from that of c...

Several amino acids are known to affect the gramicidin S producer Bacillus brevis ATCC 9999 with respect ot growth, soluble gramicidin S synthetase formation, antibiotic production, or a combination of these. Our studies confirmed that arginine has paradoxical effects on the B. brevis fermentation; it markedly increased growth and antibiotic production, yet decreased the soluble heavy gramicidi...

The possible use of Lactobacillus brevis IBRC-M10790 with degrading phytase activity was investigated in sourdough and Barbari bread –using 20 and 30% of sourdough in the formulation- in order to enhance the nutritional bioavailability, and the efficiency of the bacteria in decreasing phytate via using in sourdough was compared to yeast. Results showed that L. brevis ...

increasing in magnitude and frequency around the globe, causing extensive economic and Blooms of toxic algae are environmental impacts. On the west coast of Florida, blooms of the toxic dinoflagellate Karenia brevis (Davis) have been documented annually for the last 30 years causing respiratory irritation in humans, fish kills, and toxin bioaccumulation in shellfish beds. As a result, methods n...

OBJECTIVE Analize data on patients submitted to transfer of the pronator teres (PT) or the flexor carpi ulnaris (FCB) to the extensor carpi radialis longus/brevis (ECRL/B) in order to correct flexed wrist deformity in patients with cerebral palsy. METHOD Patients were divided into two groups: PT group and FCU group to ECRL/B. The results were evaluated by goniometry and by the functional hand...

Plant-parasitic nematodes are one of the most important pests affecting the growth of vineyards due to the destruction of new roots. Several species are associated with this problem, the most important being the ectoparasite Xiphinema index and the endoparasite Meloidogyne ethiopica. The search for new pest and disease control methods based on bioantagonist microorganisms is an important aspect...

In general, spores of B. cereus, B. megaterium, B. Sphaericus and B. subtilis strains germinated uniformly within a short time of incubation in a germination medium. In contrast, spores of B, circulans, B. brevis, B. laterosporus, B. pulvifaciens, B. polymyxa, B. pumilus, B. licheniformis and B. coagulans strains were usually slow and/or uneven germinators under the same conditions of incubatio...

This description shows the histological findings of a peroneus brevis tendon allograft used for labral reconstruction, implanted 8 weeks before being retrieved due to a postoperative complication unrelated to the graft. As far as we have knowledge this is the first description about revascularization of an allograft used for hip labral reconstruction. The histological report of the removed pero...
