cellulosimicrobium variabile sp. nov., a cellulolytic bacterium from the hindgut of the termite mastotermes darwiniensis.a novel cellulolytic and xylanolytic bacterium, strain mx5t, was isolated from the hindgut contents of the australian termite mastotermes darwiniensis (froggatt). the isolate was a facultative anaerobe and had a gram-positive cell-wall profile. the rod-shaped bacterium formed irregular coryneform and coccoid cells during growth. phylogenetic analysis of the 16s rdna provided evidence that the organism was closely related to the as-yet undescribed cellulolytic strain sr272 and the non-validly des ...200212148626
amylolytic microorganism from s+úo paulo zoo composting: isolation, identification, and amylase production.composting is a way of transforming the organic waste into fertilizer, minimizing the use of inorganic compounds that may contaminate the environment. this transformation is the result of the microorganism action, converting complex carbon sources into energy. enzymes that are exported by the microorganisms to the surrounding environment mediate this process. the aiming of the present work is to prospect the compost produced by the organic composting unit (ocu) of the funda+º+úo parque zool+¦gic ...201121845217
novel alkali-tolerant gh10 endo-β-1,4-xylanase with broad substrate specificity from microbacterium trichothecenolyticum hy-17, a gut bacterium of the mole cricket gryllotalpa orientalis.the xylh gene (1,167-bp) encoding a novel hemicellulase (41,584 da) was identified from the genome of microbacterium trichothecenolyticum hy-17, a gastrointestinal bacterium of gryllotalpa orientalis. the enzyme consisted of a single catalytic domain, which is 74% identical to that of an endo-β-1,4-xylanase (gh10) from isoptericola variabilis 225. unlike other endo-β- 1,4-xylanases from invertebrate-symbiotic bacteria, rxylh was an alkali-tolerant multifunctional enzyme possessing endo-β-1,4-xyl ...201424861346
characterization of a thermostable endoglucanase produced by isoptericola variabilis sp. idah9.this study aimed to isolate and evaluate the cellulase activity of cellulolytic bacteria in hot springs of dehloran, ilam province, iran. water and sludge samples were collected from the hot springs and the bacterial enrichment was performed in a medium containing rice barn and carboxymethyl cellulose (cmc). the cultures were incubated at 50 °c in aerobic conditions. the bacteria were isolated on cmc agar (1%) medium. cellulase assay of the isolates was measured by the evaluation of endoglucanas ...201726691485
isoptericola cucumis sp. nov., isolated from the root tissue of cucumber (cucumis sativus).a gram-stain-positive, aerobic organism, showing an irregular cell morphology, was isolated from the root tissue of cucumber (cucumis sativus) and investigated in detail for its taxonomic position. on the basis of the 16s rrna gene sequence analysis, strain ap-38t was shown to be most closely related to isoptericola variabilis (99.1 %) and isoptericola nanjingensis (98.9 %). the 16s rrna gene sequence similarity to all other species of the genus isoptericola was ≤98.5 %. dna-dna relatedness to i ...201627045419
development of novel glyphosate-tolerant japonica rice lines: a step toward commercial release.glyphosate is the most widely used herbicide for its low cost and high efficiency. however, it is rarely applied directly in rice field due to its toxicity to rice. therefore, glyphosate-tolerant rice can greatly decrease the cost of rice production and provide a more effective weed management strategy. although, several approaches to develop transgenic rice with glyphosate tolerance have been reported, the agronomic performances of these plants have not been well evaluated, and the feasibility ...201627625652
exploring the microbiota dynamics related to vegetable biomasses degradation and study of lignocellulose-degrading bacteria for industrial biotechnological application.the aims of this study were to evaluate the microbial diversity of different lignocellulosic biomasses during degradation under natural conditions and to isolate, select, characterise new well-adapted bacterial strains to detect potentially improved enzyme-producing bacteria. the microbiota of biomass piles of arundo donax, eucalyptus camaldulensis and populus nigra were evaluated by high-throughput sequencing. a highly complex bacterial community was found, composed of ubiquitous bacteria, with ...201525641069
isoptericola halotolerans sp. nov., a novel actinobacterium isolated from saline soil from qinghai province, north-west china.a gram-positive, non-motile actinobacterium, designated strain yim 70177(t), was isolated from a saline soil sample from qinghai province, north-west china. phylogenetic analysis of this organism based on 16s rrna gene sequences revealed 98.3% similarity to isoptericola variabilis dsm 10177(t). chemotaxonomic data determined for the isolate, such as the peptidoglycan type a4alpha, variation l-lys-d-asp, supported the placement of strain yim 70177(t) within the genus isoptericola. galactose was d ...200516166680
reclassification of promicromonospora pachnodae cazemier et al. 2004 as xylanimicrobium pachnodae gen. nov., comb. nov.the recently described facultatively anaerobic promicromonospora pachnodae is phylogenetically only moderately related to authentic members of promicromonospora. p. pachnodae is closely related to xylanibacterium ulmi and slightly less closely related to xylanimonas cellulosilytica and isoptericola variabilis (basonym cellulosimicrobium variabile). members of the different genera of promicromonosporaceae have similar chemotaxonomic properties; they share the same peptidoglycan type (a4alpha) and ...200415280318
isolation and characterization of a nitrile-hydrolysing bacterium isoptericola variabilis rgt01.a nitrile-hydrolysing bacterium, identified as isoptericola variabilis rgt01, was isolated from industrial effluent through enrichment culture technique using acrylonitrile as the carbon source. whole cells of this microorganism exhibited a broad range of nitrile-hydrolysing activity as they hydrolysed five aliphatic nitriles (acetonitrile, acrylonitrile, propionitrile, butyronitrile and valeronitrile), two aromatic nitriles (benzonitrile and m-tolunitrile) and two arylacetonitriles (4-methoxyph ...201425320428
reclassification of cellulosimicrobium variabile bakalidou et al. 2002 as isoptericola variabilis gen. nov., comb. already depicted in the original publication, the type strain of the species cellulosimicrobium variabile bakalidou et al. 2002, dsm 10177(t), does not cluster unambiguously with the type species, cellulosimicrobium cellulans dsm 43879(t), in phylogenetic analysis. strain dsm 10177(t) is moderately related to the recently described species xylanimonas cellulosilytica, promicromonospora pachnodae and xylanibacterium ulmi, forming a lineage that branches between c. cellulans and members of the ...200415143008
