biodiversity and characterization of aerobic spore-forming bacteria in surimi seafood products. | the microbial quality and safety of surimi seafood products was assessed by studying the prevalence and biodiversity of aerobic spore-forming bacteria at the beginning and end of shelf life in 100 surimi samples. low levels of total flora and sporulated flora were numerated at the beginning of storage, however, residual spores were detected in the majority of samples during storage. furthermore, for 34 samples, total flora counts>10(4) cfu/g were observed at the end of shelf life which could lea ... | 2010 | 21315981 |
quaternary ammonium biocides as antimicrobial agents protecting historical wood and brick. | quaternary ammonium compounds (qacs) are widely used in disinfection of water, surfaces and instruments as well as in textile, leather and food industries because of their relatively low toxicity, broad antimicrobial spectrum, non-volatility and chemical stability. due to these advantages, qacs are also used in restoration and can be applied on historical material. the aim of this study was to determine the usefulness of biocides based on quaternary ammonium salts and containing various excipien ... | 2016 | 26629794 |
modulation of fatty acid composition and growth in sporosarcina species in response to temperatures and exogenous branched-chain amino acids. | psychrotolerant endospore-forming sporosarcina species have been predominantly isolated from minced fish meat (surimi), which is stored under refrigeration after heat treatment. to develop a better method for preserving surimi-based food products, we studied the growth and fatty acid compositions of the isolated strain s92h as well as sporosarcina koreensis and sporosarcina aquimarina at cold and moderate temperatures. the growth rates of strain s92h and s. koreensis were the fastest and slowest ... | 2017 | 28331944 |
sporosarcina saromensis sp. nov., an aerobic endospore-forming bacterium. | two gram-positive, endospore-forming, rod-shaped bacterial strains, hg645(t) and hg711, were respectively isolated from surface water of a brackish lake and sediment of a fishery harbour in japan and were subsequently characterized taxonomically using a polyphasic approach. phylogenetic analyses based on 16s rrna gene sequences showed that strains hg645(t) and hg711 are affiliated phylogenetically to the genus sporosarcina, and they exhibit sequence similarities of 95.7-97.3 % to the type strain ... | 2007 | 17684272 |
sporosarcina aquimarina sp. nov., a bacterium isolated from seawater in korea, and transfer of bacillus globisporus (larkin and stokes 1967), bacillus psychrophilus (nakamura 1984) and bacillus pasteurii (chester 1898) to the genus sporosarcina as sporosarcina globispora comb. nov., sporosarcina psychrophila comb. nov. and sporosarcina pasteurii comb. nov., and emended description of th. | a light-orange-coloured, facultatively anaerobic, rod-shaped bacterium (strain sw28t), which was isolated from seawater in korea, was taxonomically studied by a polyphasic approach. this organism formed round terminal endospores in swollen sporangia. the peptidoglycan type is a4alpha, based on l-lys-l-ala-d-asp. the predominant menaquinone is mk-7 and the major fatty acid is ante-c15:0. the g+c content of the dna is 40 mol%. phylogenetic analysis based on 16s rdna sequences showed that strain sw ... | 2001 | 11411676 |
the biosynthetic pathway to a novel derivative of 4,4'-diapolycopene-4,4'-oate in a red strain of sporosarcina aquimarina. | in a red bacterial strain sf238 belonging to sporosarcina aquimarina, a c(30) carotenoid biosynthetic pathway was identified. it has been reconstructed by analysis of intermediates that accumulate in two different pigment mutants. it starts with the synthesis of 4,4'-diapophytoene and proceeds with its desaturation to 4,4'-diapolycopene, which is then oxidized to 4,4'-diapolycopene-4,4'-dioate. using a combination of hplc-pda and lc-ms/ms analyses, the final product of this pathway was identifie ... | 2012 | 22526266 |
plant growth promoting of endophytic sporosarcina aquimarina sjam16103 isolated from the pneumatophores of avicennia marina l. | endophytic sporosarcina aquimarina sjam16103 was isolated from the inner tissues of pneumatophores of mangrove plant avicennia marina along with bacillus sp. and enterobacter sp. endophytic s. aquimarina sjam16103 was gram variable, and motile bacterium measured 0.6-0.9 μm wide by 1.7-2.0 μm long and light orange-brown coloured in 3-day cultures on tryptone broth at 26°c. nucleotide sequence of this strain has been deposited in the genbank under accession number gu930359. this endophytic bacteri ... | 2012 | 22811715 |
detection of proteases from sporosarcina aquimarina and algoriphagus antarcticus isolated from antarctic soil. | two psychrophilic bacterial samples were isolated from king george island soil, in antarctica. the phylogenetic analysis based on the 16s rrna (rrs) gene led to the correlation with the closest related isolates as sporosarcina aquimarina (99%) and algoriphagus antarcticus (99%), with query coverage of 99% and 98%, respectively. the spent culture media from both isolates displayed proteolytic activities detected by sodium dodecyl sulfate polyacrylamide gel electrophoresis containing gelatin as pr ... | 2015 | 25806979 |
[phylogenetic analysis of bacteria of extreme ecosystems]. | phylogenetic analysis of aerobic chemoorganotrophic bacteria of the two extreme regions (dead sea and west antarctic) was performed on the basis of the nucleotide sequences of the 16s rrna gene. thermotolerant and halotolerant spore-forming bacteria 7t1 and 7t3 of terrestrial ecosystems dead sea identified as bacillus licheniformis and b. subtilis subsp. subtilis, respectively. taking into account remote location of thermotolerant strain 6t1 from closely related strains in the cluster staphyloco ... | 2014 | 25007437 |
