Abstract:
... In this study, a β-glucosidase coding gene (bgl) of the zygomycete fungus Rhizomucor miehei has been cloned and characterized. The gene comprises a total of 2,826 bp including the coding sequence of a 717 amino acids length putative protein and 10 introns dispersed in the whole coding region. The putative N-and C-terminal catalytic domains (aa 68 to aa 274 and aa 358-601, respectively) were identi ...

Abstract:
... A new ascomycetous yeast species, Candida neustonensis is proposed in this study based on four strains (SN92T, SN47, SJ22, SJ25) isolated from sea surface microlayer in Taiwan. These four yeast strains were morphologically, physiologically and phylogenetically identical to each other. No sexual reproduction was observed on 5% malt extract agar, corn meal agar, V8 agar, McClary's acetate agar and p ...

Abstract:
... Here we report the effects of starvation and insect age on the diversity of gut microbiota of adult desert locusts, Schistocerca gregaria, using denaturing gradient gel electrophoretic (DGGE) analysis of bacterial 16S rRNA genes. Sequencing of excised DGGE bands revealed the presence of only one potentially novel uncultured member of the Gammaproteobacteria in the guts of fed, starved, young or ol ...

Subject:
Desulfovibrio vulgaris; bioavailability; biomass production; gene expression; gene expression regulation; genes; hydrogen sulfide; iron; microarray technology; proteolysis; stress response; sulfate-reducing bacteria; transcription (genetics)
Abstract:
... Hydrogen sulfide, the metabolic end product of sulfate-reducing bacteria (SRB), is toxic to most life forms. This includes the SRB themselves. Although many of these are probably among the most sulfide resistant life forms, the presence of sulfide nevertheless presents a stress, which SRB must overcome. Although the response of SRB, especially the genus Desulfovibrio, to numerous stressors has bee ...

Abstract:
... A multilocus phylogenetic approach was applied to elucidate the phylogeny of Astragalus cicer rhizobia derived from Poland, Ukraine, and Canada. The strains selected for the studies represented three main geographically different phenons of these bacteria. Phylogenetic analyses were performed with three chromosomal housekeeping loci (16S rRNA, atpD, glnII) and three symbiotic genes located on a pl ...

Abstract:
... Thirty-two strains of phthalic acid ester (PAEs)-degrading bacteria were isolated from thirteen geographically diverse sites by enrichment using mixtures of PAEs as the sole source of carbon and energy. Sequence analyses of the 16S rRNA gene indicated that these isolates were from six genera (Arthrobacter, Gordonia, Rhodococcus, Acinetobacter, Pseudomonas, and Delftia). To evaluate the genetic div ...

Abstract:
... A rapidly growing marine derived Bacillus sp. strain NQ-11/A2, identified as Bacillus megaterium, accumulated 61% polyhydroxyalkanoate by weight. Diverse carbon sources served as substrates for the accumulation of short chain length polyhydroxyalkanoate. Three to nine granules either single or attached as buds could be isolated intact from each cell. Maximum activity of polyhydroxyalkanoate syntha ...

Abstract:
... The plant pentacyclic triterpenoids, oleanolic and ursolic acids, inhibit the growth and survival of many bacteria, particularly Gram-positive species, including pathogenic ones. The effect of these compounds on the facultative human pathogen Listeria monocytogenes was examined. Both acids affected cell morphology and enhanced autolysis of the bacterial cells. Autolysis of isolated cell walls was ...

EDTA (chelating agent); Helicobacter pylori; bacteria; enzyme kinetics; enzymes; genes; metabolism; phosphates; phosphonates; spectroscopy; starvation
Abstract:
... Helicobacter pylori has been shown to degrade two phosphonates, N-phosphonoacetyl-l-aspartate and phosphonoacetate; however, the bacterium does not have any genes homologous to those of the known phosphonate metabolism pathways suggesting that H. pylori may have a novel phosphonate metabolism pathway. Growth of H. pylori on phosphonates was studied and the catabolism of these compounds was measure ...
