| halomonas magadii sp. nov., a new member of the genus halomonas, isolated from a soda lake of the east african rift valley. | a number of novel alkaliphilic organotrophic bacteria have been isolated from several saline and alkaline east african soda lakes. the new isolates grow at ph values between 7.0 and 11.0, with ph optima for growth between 9.0 and 10.0. growth occurs at total salts concentration between 0% and 20% (w/v) with optimum at 0%-7% (w/v). phylogenetic analyses based on 16s rdna sequence comparison indicate that these isolates are related (>96% similarity) to members of the halomonadaceae within the gamm ... | 2000 | 10741837 |
| a detailed phenotypic characterisation of the type strains of halomonas species. | we have made a detailed phenotypic characterisation of the type strains of 21 species within the genus halomonas and have also studied any possible intraspecific variation of strains within h. eurihalina, h. halophila, h. maura and h. salina. we used 234 morphological, physiological, biochemical, nutritional and antimicrobial susceptibility tests. nutritional assays were carried out using both classical and miniaturized (biolog system) identification methods. two different numerical analyses wer ... | 2002 | 12421074 |
| lipase-producing microorganisms from a kenyan alkaline soda lake. | lipolytic enzyme production of 150 isolated strains from samples of lake bogoria (kenya) was examined. among these, fifteen isolates were selected on the basis of their lipolytic activities and subjected to morphological and 16s rrna gene sequencing analyses for their identification. all the microorganisms have been selected under culture conditions with ph ranges between 7-10 and temperatures of 37-55 degrees c. most of them showed optimal growth at 37 degrees c and tolerated salinity up to 10% ... | 2004 | 15000472 |
| halomonas gudaonensis sp. nov., isolated from a saline soil contaminated by crude oil. | two moderately halophilic strains, sl014b-69(t) and sl014b-62a2, were isolated from a saline soil contaminated with crude oil in gudao in the coastal shengli oilfield in china; the isolates were gram-negative, rod-shaped and carried lateral flagella. growth occurred at nacl concentrations of 1-20 % (w/v), at temperatures of 10-42 degrees c and at ph 8.0-9.0. strain sl014b-69(t) had c(18 : 1)omega7c (28.61 %), c(19 : 1) cyclo omega7c (27.97 %), c(16 : 0) (19.66 %) and c(12 : 0) 3-oh (8.87 %) as t ... | 2007 | 17473232 |
| halomonas daqingensis sp. nov., a moderately halophilic bacterium isolated from an oilfield soil. | a gram-negative, moderately halophilic, short rod-shaped, aerobic bacterium with peritrichous flagellae, strain dqd2-30(t), was isolated from a soil sample contaminated with crude oil from the daqing oilfield in heilongjiang province, north-eastern china. the novel strain was capable of growth at nacl concentrations of 1-15 % (w/v) [optimum at 5-10 % (w/v)]. phylogenetic analyses based on 16s rrna gene sequences showed that the novel strain belonged to the genus halomonas in the class gammaprote ... | 2008 | 19060072 |
| halotolerant pgprs prevent major shifts in indigenous microbial community structure under salinity stress. | the resilience of soil microbial populations and processes to environmental perturbation is of increasing interest as alteration in rhizosphere microbial community dynamics impacts the combined functions of plant-microbe interactions. the present study was conducted to investigate the effect of inoculation with halotolerant rhizobacteria bacillus pumilus (str2), halomonas desiderata (str8), and exiguobacterium oxidotolerans (str36) on the indigenous root-associated microbial (bacterial and funga ... | 2015 | 25542205 |
| halomonas heilongjiangensis sp. nov., a novel moderately halophilic bacterium isolated from saline and alkaline soil. | a moderately halophilic bacterium, designated strain 9-2(t), was isolated from saline and alkaline soil collected in lindian county, heilongjiang province, china. the strain was observed to be strictly aerobic, gram-negative, rod-shaped, oxidase-positive, catalase-positive and motile. it was found to require nacl for growth and to grow at nacl concentrations of 0.5-14 % (w/v) (optimum, 7-10 %, w/v), at temperatures of 10-45 °c (optimum 25-30 °c) and at ph 5.0-10.0 (optimum ph 8.0). phylogenetic ... | 2015 | 26036672 |
| halomonas desiderata as a bacterial model to predict the possible biological nitrate reduction in concrete cells of nuclear waste disposals. | after closure of a waste disposal cell in a repository for radioactive waste, resaturation is likely to cause the release of soluble species contained in cement and bituminous matrices, such as ionic species (nitrates, sulfates, calcium and alkaline ions, etc.), organic matter (mainly organic acids), or gases (from steel containers and reinforced concrete structures as well as from radiolysis within the waste packages). however, in the presence of nitrates in the near-field of waste, the waste c ... | 2014 | 24275342 |
