Background: The biological assessment of trimethoprim organotin complexes is the subject work discussed in this publication. Objective: purpose project to investigate properties tin and via characterizing their IR NMR elemental analysis sensitivity. Material methods: These combine octahedral ML6 pyramidal ML5 by allowing amino groups present medicinal ingredients react with (IV). Results: compl...

Plant growth-promoting rhizobacteria (PGPR) may provide a biological alternative to fix atmospheric N2 and delay N remobilisation in maize plant to increase crop yield, based on an understanding that plant-N remobilisation is directly correlated to its plant senescence. Thus, four PGPR strains were selected from a series of bacterial strains isolated from maize roots at two locations in Malaysi...

ABSTRACT We evaluated combinations of two strains of plant growth-promoting rhizobacteria (PGPR) formulated with the carrier chitosan for the ability to induce growth promotion of tomato plants and resistance to infection by Cucumber mosaic virus (CMV). Each PGPR combination included GB03 (Bacillus subtilis) and one of the following PGPR strains: SE34 (B. pumilus), IN937a (B. amyloliquefaciens)...

Between April 2000 and May 2005, 350 bacteraemic episodes occurred among patients treated in our haematology unit. Two hundred and twenty-eight of these episodes were caused by Gram-positive pathogens, most commonly coagulase-negative staphylococci and Staphylococcus aureus. One hundred and twenty-two episodes were due to Gram-negative pathogens, with a predominance of Escherichia coli, Acineto...

ABSTRACr Plasmid pUB10 (-2.8 X 106 daltons), originally detected in Staphylococcus aureus, specifies resistance to neomycin and has been transformed into Bacillus subtilis 168. In B. subtifis, pUBllO is stably maintained at about 50 copies per chromosome and renders the host resistant to neomycin sulfate at 5 jg/ml. pUBlIO isolated from B. subtifis transforms Rec+ and recE4-containing strains o...

The spores of several Bacillus species, including Bacillus pumilus SAFR-032 and B. safensis FO-36b, which were isolated from the spacecraft assembly facility at NASA's Jet Propulsion Laboratory, are unusually resistant to UV radiation and hydrogen peroxide. In order to identify candidate genes that might be associated with these resistances, the whole genome of B. pumilus SAFR-032, and the draf...

BACKGROUND Chitin is an abundant natural polysaccharide found in fungi, algae, and exoskeleton of insects. Several bacterial species are capable of utilizing chitin as their carbon source. These bacteria produce chitinases for degradation of chitin into N-acetyl-D-glucosamine. So far, regulation of the chitinase encoding genes has been studied in different bacterial species. Among Bacillus spec...

Endophytic bacteria associated with the fern Dicksonia sellowiana were investigated. The bacterial communities from the surface-sterilized pinnae and rachis segments of the plants from the Brazilian Atlantic Rainforest that grew in native field conditions were compared with the bacterial communities from plants grown in greenhouses and plants that were initially grown in greenhouses and then tr...

The bacteria of food packaging paper and board were studied. Most of the aerobic strains were spore-formers; members of the genus Bacillus with B. cereus group (B. cereus, B. mycoides, B. thuringiensis), B. polymyxa group (B. polymyxa, B. circulans, B. macerans, B. pabuli), B. brevis and B. licheniformis predominated. The main source of spore-forming bacteria in paper and board was the broke (r...
