Two new members of the genus Thiomicrospira were isolated from an intertidal mud flat sample with thiosulfate as the electron donor and CO2 as carbon source. On the basis of differences in genotypic and phenotypic characteristics, it is proposed that strain JB-A1T (= DSM 12350T) and strain JB-A2T (= DSM 12351T) are members of two new species, Thiomicrospira kuenenii and Thiomicrospira frisia, r...
A Gram-negative, rod-shaped, non-spore-forming, slightly halophilic bacterium (strain TF-17T) was isolated from an intertidal sediment from the Yellow Sea, Korea. Pigment of strain TF-17T was similar to that of Microbulbifer elongatus, but different from those of Microbulbifer hydrolyticus and Microbulbifer salipaludis. Strain TF-17T was distinguishable from M. elongatus by some phenotypic prop...
From granular sludge from a laboratory-scale upflow anaerobic sludge bed reactor operated at 55 degrees C with a mixture of volatile fatty acids as feed, a novel anaerobic, moderately thermophilic, syntrophic, spore-forming bacterium, strain TPO, was enriched on propionate in co-culture with Methanobacterium thermoautotrophicum Z245. The axenic culture was obtained by using pyruvate as the sole...
Characterization of biocontrol activity of two yeast strains from Uruguay against blue mold of apple
In the present study, two yeast antagonists, Cryptococcus laurentii (strain 317) and Candida ciferrii (strain 283) isolated from the surface of healthy apples, controlled blue mold of apple caused by Penicillium expansum. Both antagonists reduced the incidence of blue mold by 80% at 25 °C. At 5 °C C. ciferrii (strain 283) maintained the efficacy of disease control, but C. laurentii (strain 317)...
BACKGROUND Campylobacter jejuni is a leading cause of bacterial enteritis worldwide. This microaerophilic bacterium can survive in aerobic environments, suggesting it has protective mechanisms against oxidative stress. The clinical C. jejuni Bf strain is characterized by an increased resistance to oxygen. This study aimed to characterize the behavior of the clinical C. jejuni Bf strain under an...
The Montreal Biodome operates a methanol-fed denitrification system that treats the water in its three million litre marine mesocosm. An unknown bacterium, named strain NL21T, was isolated from this system on TSA and R2A agar. The organism is a Gram-negative, rod-shaped (1x3 microm) facultative aerobe. Optimal growth conditions on R2A agar are 30-35 degrees C, pH 7-7.5 and 1% (w/w) NaCl. Phylog...
A split Hopkinson pressure bar is used to investigate the dynamic mechanical properties of biomedical 316L stainless steel under strain rates ranging from 1 × 10(3) s(-1) to 5 × 10(3) s(-1) and temperatures between 25°C and 800°C. The results indicate that the flow stress, work-hardening rate, strain rate sensitivity, and thermal activation energy are all significantly dependent on the strain, ...
Bacteriophage release in a lysogenic strain of Agrobacterium tumefaciens V-1 is temperature-sensitive. At 25 C and 30 C, phage was released in a ratio of 1 plaque-forming unit per 100 bacteria; at 35 C, although bacterial growth was not inhibited, phage release was suppressed. Phage synthesis was induced by heat shock, 42 C for 30 min, ultraviolet irradiation, and mitomycin C. Induction by ultr...
This study aimed to estimate the distribution of hepatitis B virus (HBV) C/D recombinant in Han and Tibet patients with chronic hepatitis B (CHB) and then learn such strain's replication capacity in vivo. A total of 331 serum samples were collected from Han outpatients from Sichuan Province and Tibetan outpatients from Tibet. Viral genotypes in these samples were identified. An HBV replicative ...
A novel Gram-negative, obligately aerobic, non-motile, rod-shaped bacterium, strain M97(T), was isolated from marine sediment of a cage-cultured ark clam farm on the south coast of Korea. Strain M97(T) was positive for oxidase and catalase. Optimal growth occurred at 37 °C, with 1-2 % (w/v) NaCl and at pH 7-8. The main cellular fatty acids were C(16 : 0), C(18 : 1)ω7c, C(12 : 0) 3-OH and cyclo-...
