Lysinibacillus sphaericus strains belonging the antigenic group H5a5b produce spores with larvicidal activity against larvae of Culex mosquitoes. C7, a new isolated strain, which presents similar biochemical characteristics and Bin toxins in their spores as the reference strain 2362, was, however, more active against larvae of Culex mosquitoes. The contribution of the surface layer protein (S-l...

Exit-site infection is an unwanted complication in patients with indwelling catheter. However, such by uncommon organism like Lysinibacillus which otherwise considered environmental contaminant needs to be mentioned. Our report describes one case. The patient was given antibiotic as per susceptibility he responded.

S-layers are two-dimensional protein or glycoprotein lattices that cover the surfaces of many bacteria and archaea. Because they constitute the first interface of interaction between microorganisms and their environment, hosts, and predators, they are of great biological interest. Moreover, owing to their nanoscale, periodic, porous structure and relative ease of manipulation, they have the pot...

Lysinibacillus sphaericus D3 cell-immobilized beads in natural gel sodium alginate decolorized the xylidine orange dye 1-(dimethylphenylazo)-2-naphthol-6-sulfonic acid sodium salt in the laboratory. Optimal conditions were selected for decolorization and the products formed were evaluated for toxicity by disc diffusion assay against common marine bacteria which revealed the non-toxic nature of ...

The objective of this work was to characterize reference bacteria strains, belonging the genus Bacillus and species correlated genera, by simplified morphological biochemical methods. characterization is based on aspects colonies, as well cytomorphology species, optical scanning microscopy. For characterization, sensitivity test antimicrobials disk-diffusion performed. Moreover, strains were ch...
