During a survey of the mycobiota sourgrass (Digitaria insularis), graminaceous weed from Brazil, severe foliage blight symptoms were observed on plants at different places state Minas Gerais. A fungus identified as Bipolaris yamadae, after polyphasic study, including analysis ITS, GPDH and TEF-1α genes, was isolated diseased tissues. Pathogenicity to confirmed through inoculations healthy plant...

In this paper two external schema generation algorithms are presented. These algorithms are defined in the framework of the new external schema definition methodology for OODBs put forward in (Samos, 1995); they generate an external schema from a set of classes selected from those existing in an external schema definition repository. Their main characteristic is that they avoid the generation o...

Benthic cyanobacterial mats are an integral component of aquatic communities in tropical marine waters. These can develop into massive nuisances at risk expansion due to climate change. The extent diversity occurring within these mats, still remains largely unexplored, especially Florida. To reveal this diversity, coastal environments South Florida were sampled and subsequently processed for is...

Twenty-six root nodule bacteria from two native forage legumes namely Sulla aculeolata subsp. and mauritanica were isolated analyzed using a polyphasic approach comprising phenotypic traits, ERIC-PCR, 16S rRNA gene sequencing. This is the first time study has been performed to determine diversity of associated with spp. Phenotypically, all isolates identified as fast-growing shows high toleranc...

Five bacterial strains (SYSU YG23T, SYSU 10HL1970T, 10HP82-10, 10HL1938, 10HP457) isolated from water reservoirs of cooling systems were characterized using a polyphasic taxonomic approach. The isolates were Gram-stain-negative, strictly aerobic and non-motile. Growth was enhanced in the presence of l-cysteine. The major fatty acids (>5 %) for the five strains were C10 : 0, C16 : 0, C16 : 0 3-O...

A novel strain, Streptomyces antioxidans MUSC 164(T) was recovered from mangrove forest soil located at Tanjung Lumpur, Malaysia. The Gram-positive bacterium forms yellowish-white aerial and brilliant greenish yellow substrate mycelium on ISP 2 agar. A polyphasic approach was used to determine the taxonomy status of strain MUSC 164(T). The strain showed a spectrum of phylogenetic and chemotaxon...

The late 19th century was the beginning of bacterial taxonomy and bacteria were classified on the basis of phenotypic markers. The distinction of prokaryotes and eukaryotes was introduced in the 1960s. Numerical taxonomy improved phenotypic identification but provided little information on the phylogenetic relationships of prokaryotes. Later on, chemotaxonomic and genotypic methods were widely ...
