Phenotypic and phylogenetic analyses show Microcoleus chtonoplastes to be a cosmopolitan cyanobacterium
Article Abstract:
The biological diversity in the phenotypic and phylogenetic characters of the Microcoleus chthonoplastes cynobacterium field population, and the corresponding culture strains indicates a cosmopolitan distribution. The PCC 7420 strain also shows the same phenotype and 16S rRNA gene sequence but the strains SAG 3192 and 10mfx fail to do so. The cynobacterium has 2 hydrogen peroxide-removing enzymes, namely, ascorbate peroxidase and catalase. The gilding mobility of the population samples and core strains range between 0.3 and 0.6 micrometer s(super -1).

Effectiveness of chemometric techniques in discrimination of Lactobacillus helveticus biotypes from natural dairy starter cultures on the basis of phenotypic characteristics
Article Abstract:
Cell wall protein profiles and the chemometric evaluation of some phenotypic parameter were used to distinguish 74 Lactobacillus helveticus strains isolated from grana and provolone cheese natural whey starters. Of the different phenotypes evaluated, no single specific parameter allowed the two groups of strains to be separated. Results revealed that cell wall protein patterns permit L helveticus strains isolated from grana cheese natural whey starters to be differentiated from those isolated from provolone cheese natural whey starters.

Natural dissemination of Bacillus anthracis spores in Northern Canada
Article Abstract:
Soil samples were collected from North Canada and were screened for viable Bacillus anthracis spores via selective culture, phenotypic analysis and PCR. The comparison of samples from minimally scavenged and fully necropsied carcass sites showed no statistically significant difference in the level of Bacillus anthracis spore contamination and hence the immediate area around a suspected anthrax carcass should be considered substantially contaminated regardless of the condition of the carcass.
