Nostoc is a diverse genus of filamentous cyanobacteria with tremendous potential for agricultural and industrial applications. Morphometric methods and routine 16S rDNA-based identification undermines the genetic diversity and impedes strain-level differentiation. A comparative study to deduce the discriminatory power of random amplified polymorphic DNA (RAPD) and amplified ribosomal DNA restri...

In recent years, the importance of the Gram-negative bacterium Stenotrophomonas as an opportunistic pathogen as well as in biotechnology has increased. The aim of the present study was to develop new methods for distinguishing between strains closely related to the potentially human pathogenic Stenotrophomonas maltophilia and those closely related to the plant-associated Stenotrophomonas rhizop...

BACKGROUND AND PURPOSE Twenty lactobacilli isolated from vaginal samples of healthy volunteers were characterized according to polyphasic taxonomy. A broad spectrum of activity and protective properties of these vaginal isolates has been reported. METHODS Phenotypic and genotypic methods such as random amplified polymorphic DNA (RAPD), species-specific and BOX polymerase chain reaction (PCR),...

Inland solar salterns established in the vicinity of Sambhar Lake are extreme saline environments with high salinity and alkalinity. In view of the fact that microbes inhabiting such extreme saline environments flourish the contemporary bioprospecting, it was aimed to selectively isolate slow growing and rare actinomycetes from the unexplored solar salterns. A total of 14 slow growing actinomyc...

A molecular technique based on the restriction fragment length polymorphism of the 16S ribosomal genes amplified by a polymerase chain reaction (PCR), referred to as amplified 16S ribosomal DNA restriction analysis (ARDRA), was designed to identify 19 Avibacterium paragallinarum strains isolated from infraorbital sinus and nasal turbinate bone samples of broiler chickens, breeders, and laying h...

Background: Traditional dairy products are the main sources for probiotic bacteria. This study aimed to isolate and characterize the potentially probiotic Lactobacillus strains isolated from traditional dairy products in Iran. Methods: Microbial population of each dairy product was enriched and screened for acid- and bile- resistant strains. The isolates were ...

The bacterial community of maple sap was characterized by analysis of samples obtained at the taphole of maple trees for the 2001 and 2002 seasons. Among the 190 bacterial isolates, 32 groups were formed according to the similarity of the banding patterns obtained by amplified ribosomal DNA restriction analysis (ARDRA). A subset of representative isolates for each ARDRA group was identified by ...
