Moderately acidophilic mesorhizobia isolated from chickpea.
AIMS Our aim was to evaluate the effect of acid and alkaline pH on chickpea rhizobia, and on chickpea-rhizobia symbiosis. METHODS AND RESULTS Forty-seven rhizobia isolates obtained from 12 Portuguese soils were grown at pH 5, 7 and 9. Among these, 26 grew more at pH 5 than at 7, suggesting the existence of acidophiles. All isolates were identified as mesorhizobia by 16S rDNA partial sequence ...
متن کاملHalarchaeum nitratireducens sp. nov., a moderately acidophilic haloarchaeon isolated from commercial sea salt.
Two halophilic moderately acidophilic archaeal strains, MH1-136-2(T) and MH1-370-1 were isolated from commercial salt samples made from seawater in Japan and Indonesia, respectively. Cells of the two strains were pleomorphic and Gram-stain-negative. Strain MH1-136-2(T) was pink pigmented, while MH1-370-1 was orange-red pigmented. Strain MH1-136-2(T) was able to grow at 9-30 % (w/v) NaCl (with o...
متن کاملAcidophilic haloarchaeal strains are isolated from various solar salts
Haloarchaeal strains require high concentrations of NaCl for their growth, with optimum concentrations of 10-30%. They display a wide variety of morphology and physiology including pH range for growth. Many strains grow at neutral to slightly alkaline pH, and some only at alkaline pH. However, no strain has been reported to grow only in acidic pH conditions within the family Halobacteriaceae.In...
متن کاملGenome Sequence of the Moderately Acidophilic Sulfate-Reducing Firmicute Desulfosporosinus acididurans (Strain M1T)
Microbial dissimilatory sulfate reduction is commonplace in many anaerobic environments, though few acidophilic bacteria are known to mediate this process. We report the 4.64-Mb draft genome of the type strain of the moderate acidophile Desulfosporosinus acididurans, which was isolated from acidic sediment in a river draining the Soufrière volcano, Montserrat.
متن کاملEnumeration and characterization of acidophilic microorganisms isolated from a pilot plant stirred-tank bioleaching operation.
Microorganisms were enumerated and isolated on selective solid media from a pilot-scale stirred-tank bioleaching operation in which a polymetallic sulfide concentrate was subjected to biologically accelerated oxidation at 45 degrees C. Four distinct prokaryotes were isolated: three bacteria (an Acidithiobacillus caldus-like organism, a thermophilic Leptospirillum sp., and a Sulfobacillus sp.) a...
