Reclassification of Bacillus axarquiensis Ruiz-Garcia et al. The Bacillus subtilis group encompasses the taxa Bacillus subtilis subsp. In this study, the taxonomic bacollus between the species B.

Based on these molecular taxonomic data and the lack of phenotypic distinctive characteristics, Bacillus axarquiensis and Bacillus malacitensis should be reclassified as later heterotypic synonyms of Bacillus mojavensis.

Our work focuses on the use of microorganisms to recover petroleum hydrocarbons that remain entrapped after current recovery technologies reach their economic limit. Capillary forces between the hydrocarbon and aqueous phases are largely responsible for trapping the hydrocarbons in the pores of the rock and large reductions in the interfacial tension between the hydrocarbon and aqueous phases are needed for hydrocarbon mobilization10, Microorganisms produce a variety of biosurfactants 4several of which generate the ultra low interfacial tensions needed for hydrocarbon mobilization 4, 5, 8.

In particular, the lipopeptide biosurfactant produced by Bacillus mojavensis strain JF-2 reduces the interfacial tension between hydrocarbon and aqueous phases to very low levels mojavensis JF-2 grows under the environmental conditions found in many oil reservoirs, i.

However, anaerobic growth of B. Our initial studies revealed that enzymatic digests, such as Proteose Peptone, were required for anaerobic growth of Bacillus mojavensis JF Subsequent purification of the growth-enhancing factor in Proteose Peptone resulted in the identification of the growth-enhancing factor as DNA or deoxyribonucleosides.

Further, we found that JF-2 required all four deoxyribonucleosides deoxyadeonosine, deoxyguanosine, deoxycytidine and thymidine for growth under strict anaerobic conditions. The requirement for the deoxyribonucleosides did not occur under aerobic growth conditions.

DNA was not used as a sole energy source; sucrose was required. Application for Diesel Biodegradation.

This work concerns the study of the enhancement of surfactin and fengycin production by Licueniformis. The influences of the culture medium and cells immobilization were studied.

The use of immobilized cells seemed to be a promising method for improving lipopeptides productivity. In fact, the synthesis of both lipopeptides, mainly fengycin, was greatly enhanced by the immobilization of A21 cells.

Considering these properties, B. Directory of Open Access Journals Sweden.

Complete genome sequence of the industrial bacterium Bacillus licheniformis and comparisons with closely related Bacillus species. Background Bacillus licheniformis is a Gram-positive, spore-forming soil caracterisficas that is used in the biotechnology industry to manufacture enzymes, antibiotics, biochemicals and consumer products.

This species is licueniformis related to the well studied model organism Bacillus subtilis, and produces an assortment of extracellular enzymes that may contribute to nutrient cycling in nature. Results We determined the complete nucleotide sequence of the B. Conclusions Despite the unmistakable organizational similarities between the B. Differences include a region of more than 80 kilobases kb that comprises a cluster of polyketide synthase genes and a second baacillus of 38 kb encoding plipastatin synthase enzymes that are absent in the B.

The availability of a completed genome sequence for B.


From Genome to Function: Bacillus subtilis is a sporulating Gram-positive bacterium that lives primarily in the soil and associated water sources. Whilst this bacterium has been studied extensively in the laboratory, relatively few studies have been undertaken to study its activity in natural environments. The publication of the B.

In this paper we discuss analytical approaches that are being developed to relate genes to function in environments such as the rhizosphere.

Complete genome sequence of a representative strain, B. Two Caracteristicaa, endospore-forming bacterial strains, CRT and CRb, which produce surfactant molecules are described.

Phenotypic tests and phylogenetic analyses showed these strains to be members of acracteristicas genus Bacillus and related to the species Bacillus atrophaeus, Bacillus mojavensisBacillus subtilis, Bacillus vallismortis and Bacillus amyloliquefaciens, although they differ from these species in a number of phenotypic characteristics.

The main fatty acids in strain CRT are In the light of the polyphasic evidence gathered in this study, it is proposed that these strains be classified as a novel species of the genus Bacilluswith the name Bacillus velezensis sp. A microsatellite linkage map of Drosophila mojavensis.

Full Text Available Abstract Background Drosophila mojavensis has been a model system for genetic studies of ecological adaptation and speciation. However, despite its use for over half a century, no linkage map has been produced for this species or its close relatives.

Results We have developed and mapped 90 microsatellites in D. A slight excess of repetitive sequence was observed on the X-chromosome relative to the autosomes, and the linkage groups have a greater recombinational length than the homologous D.

We also confirmed the conservation of Muller’s elements in 23 sequences between D. Conclusions The microsatellite primer sequences and localizations are presented here and made available to the public. This map will facilitate future quantitative trait locus mapping studies of phenotypes involved in adaptation or reproductive isolation using this species.

Cells were facultatively anaerobic, terminal endospore-forming and motile by means of peritrichous flagella. Colonies were yellowish and the cells showed oxidase-negative and catalase-positive reactions.

The predominant menaquinone was MK The major fatty acids were anteiso-C The cellular polar lipids contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four unknown phospholipids and one unknown aminophospholipid.

A polyphasic taxonomic study based on morphological, physiological, biochemical and phylogenetic data indicated that strain EGI T represents a novel species of the genus Bacillusfor which the name Bacillus tamaricis sp. Antimicrobial polyketide furanoterpenoids from seaweed-associated heterotrophic bacterium Bacillus subtilis MTCC This bacterium was positive for polyketide synthetase gene KCand therefore, was selected to bioprospect specialized metabolites bearing polyketide backbone.

Global microarray analysis of carbohydrate use in alkaliphilic hemicellulolytic bacterium Bacillus sp. Full Text Available The alkaliphilic hemicellulolytic bacterium Bacillus sp.


N has a broad substrate spectrum and exhibits the capacity to utilize complex carbohydrates such as galactomannan, xylan, and pectin. In the monosaccharide mixture, sequential utilization by Bacillus sp. Glucose appeared to be its preferential monosaccharide, followed by fructose, mannose, arabinose, xylose, and galactose. Global transcription profiles of the strain were determined separately for growth on six monosaccharides glucose, fructose, mannose, galactose, arabinose, and xylose and four polysaccharides galactomannan, xylan, pectin, and sodium carboxymethylcellulose using one-color microarrays.

Numerous genes potentially related to polysaccharide degradation, sugar transport, and monosaccharide metabolism were found to respond to a specific substrate. Putative gene clusters for different carbohydrates were identified according to transcriptional patterns and genome annotation. Identification and analysis of these gene clusters contributed to pathway reconstruction for carbohydrate utilization in Bacillus sp. Several genes encoding putative sugar transporters were highly expressed during growth on specific sugars, suggesting their functional roles.

Two phosphoenolpyruvate-dependent phosphotransferase systems were identified as candidate transporters for mannose and fructose, and a major facilitator superfamily transporter was identified as a candidate transporter for arabinose and xylose. Five carbohydrate uptake transporter 1 family ATP-binding cassette transporters were predicted to participate in the uptake of hemicellulose and pectin degradation products. Collectively, microarray data improved the pathway reconstruction involved in carbohydrate utilization of Bacillus sp.
