    Autotrophic carbon dioxide fixation in Acidianus brierleyi (1997)
    Springer
    Archives of microbiology 166 (1997), S. 368-371 
    Details
    ISSN: 1432-072X
    Keywords: Key wordsAcidianus brierleyi ; Reductive tricarboxylic ; acid cycle ; 3-Hydroxypropionate cycle

    Topics: Biology
    Notes: Abstract The autotrophic CO2 fixation pathway in Acidianus brierleyi, a facultatively anaerobic thermoacidophilic archaebacterium, was investigated by measuring enzymatic activities from autotrophic, mixotrophic, and heterotrophic cultures. Contrary to the published report that the reductive tricarboxylic acid cycle operates in A. brierleyi, the enzymatic activity of ATP:citrate lyase, the key enzyme of the cycle, was not detected. Instead, activities of acetyl-CoA carboxylase and propionyl-CoA carboxylase, key enzymes of the 3-hydroxypropionate cycle, were detected only when A. brierleyi was growing autotrophically. We conclude that a modified 3-hydroxypropionate pathway operates in A. brierleyi.

    Topics: Biology
    Notes: Abstract Two form ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) genes from the obligately autotrophic, marine hydrogen oxidizer Hydrogenovibrio marinus were sequenced. The deduced amino acid sequences of both RuBisCOs revealed that they are similar to those of sulfur oxidizers (Thiobacillus) and a purple sulfur bacterium (Chromatium vinosum). According to the 16S rRNA gene sequences, H. marinus is also affiliated with these microorganisms, members of Thiomicrospira being the closest relatives. Sequence similarities of the 16S rRNA genes and of the RuBisCO genes among these γ-Proteobacteria suggest a common autotrophic ancestry. An ancestor of purple sulfur bacteria might be a common root of H. marinus and related sulfur oxidizers.

    Purification and characterization of pyruvate:ferredoxin oxidoreductase from Hydrogenobacter thermophilus TK-6 (1997)
    Springer

    ISSN: 1432-072X
    Keywords: Key wordsHydrogenobacter thermophilus ; Reductive tricarboxylic acid cycle ; Pyruvate:ferredoxin ; oxidoreductase
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Pyruvate:ferredoxin oxidoreductase was purified to electrophoretic homogeneity from an aerobic, thermophilic, obligately chemolithoautotrophic, hydrogen-oxidizing bacterium, Hydrogenobacter thermophilus TK-6, by precipitation with ammonium sulfate and fractionation by DEAE-Sepharose CL-6B, polyacrylate-quaternary amine, hydroxyapatite, and Superdex-200 chromatography. The native enzyme had a molecular mass of 135 kDa and was composed of four different subunits with apparent molecular masses of 46, 31.5, 29, and 24.5 kDa, respectively, indicating that the enzyme has an αβγδ-structure. The activity was detected with pyruvate, coenzyme A, and one of the following electron acceptors in substrate amounts: ferredoxin isolated from H. thermophilus, FAD, FMN, triphenyltetrazolium chloride, or methyl viologen. NAD, NADP, and ferredoxins from Chlorella spp. and Clostridium pasteurianum were ineffective as the electron acceptor. The temperature optimum for pyruvate oxidation was approximately 80° C. The pH optimum was 7.6–7.8. The apparent K m values for pyruvate and coenzyme A at 70° C were 3.45 mM and 54 μM, respectively. The enzyme was extremely thermostable under anoxic conditions; the time for a 50% loss of activity (t 50%) at 70° C was approximately 8 h.

    Topics: Biology
    Notes: Abstract  The expression of the Arabidopsis heat-shock protein (HSP) 18.2 promoter β-d-glucuronidase (GUS) chimera gene was studied in various organs of the transgenic Nicotiana plumbaginifolia during the recovery phase at normal temperatures (20–22  °C) following heat-shock (HS) treatment. The optimum HS temperature for GUS activity in the anthers, petals and capsules was 42  °C, but in immature seeds and the placentas of capsules it was 36  °C and 39  °C, respectively. No apparent GUS activity was observed in any organs except for dry seeds after HS at 45  °C, although the activity in dry seeds was apparent even after HS at 48  °C. After HS at 42  °C, GUS activity in the flower tissues was the highest before anthesis and declined thereafter.

    Delayed recovery of β-glucuronidase activity driven by an Arabidopsis heat shock promoter in heat-stressed transgenic Nicotiana plumbaginifolia (1999)

    Notes: Abstract  The expression of the Arabidopsis heat shock protein (HSP) 18.2 promoter-β-d-glucuronidase (GUS) chimera gene was investigated in transgenic Nicotiana plumbaginifolia plants during the recovery phase at normal temperatures (20–22  °C) after a heat shock (HS) treatment. GUS activity increased during the recovery phase after HS at 42  °C for 2 h, and maximal GUS activity was observed after 12 h at normal temperatures, at levels 50–100 times higher than the activity immediately after HS. After HS at 44  °C, little GUS activity was observed during the first 20–24 h at normal temperatures, but the activity increased gradually thereafter, to reach a maximum at 40–50 h. After HS at 45  °C, no GUS activity was observed throughout the experimental period. RT-PCR analysis showed that GUS mRNA remained for 10 h after a 2-h HS at 42  °C and for 40 h after a 2-h HS at 44  °C. These findings demonstrate that brief HS treatment, especially at a sublethal temperature, induces a long-term accumulation of HSP-GUS mRNA during the recovery phase.

    Keywords: Key wordsAtropa belladonna ; Transformed root cultures ; Scale-up ; Tropane alkaloids ; Modified stirred bioreactors

    Topics: Biology
    Notes: Abstract A scale up of transformed root cultures of Atropa belladonna from a 300-ml flask to a 30-l tank was accomplished without any reduction in alkaloid productivity. Cutting treatment of seed cultures showed no distinct effect on root growth, morphology, and alkaloid content in conical flasks during 1 month of culture. Randomly cut roots thus grown were further cultivated in 3-l and 30-l modified stirred bioreactors for a scale-up culture. After 1 month of culture, 1490 mg of tropane alkaloids was produced by a 30-l culture of A. belladonna transformed roots. These roots contained the same level of atropine (5.4 mg/ g dw) as the roots of this plant grown in the field for 12 months and still contained a considerable amount of other alkaloids including 1.6 mg/g dw of 6-β-hydroxyhyoscyamine, 0.9 mg/g dw of scopolamine, and 2.0 mg/g dw of littorine.

    Notes: Abstract Intensive observations of chemical species in aerosols, gases and other samples at the summit of Mt. Fuji and at Tarobo (at 1300m on the mountain'ts southern slope) was performed from July 28 to Aug. 3, 1993 and from July 25 to 30,1994. The most interesting observation was the abrupt increase in the sulfate concentration in aerosol collected in July, 1993 just after the typhoon (number 9306) passed the Japanese archipelago and the wind direction shifted from south to west. Chemical analysis indicated this aerosol was acidic. In contrast, the summit aerosol observed in 1994 was not acidic following a less dramatic rise in sulfate content. Back trajectory analyses were used to extrapolate from these measurement to an inventory of polluted air over the Asian Continent. The concentrations of gaseous SO2 and HCl remained low during both observation periods, with some higher concentrations of NH3.

    Notes: Abstract Atmospheric concentration and total (wet plus dry) and dry deposition of210Pb and7Be have been measured at our laboratory in Ishikawa Prefecture in Japan which faced the Sea of Japan during 1993–1994. At the same time inventories of excess210Pb in soil samples were measured from a mixed pine forest. On the basis of the data obtained, an attempt was made to evaluate the dry deposition velocity as a result of the interception by the canopies of airborne210Pb in a pine stand The dry deposition velocity of210Pb in the pine stand was roughly estimated to be 0.9–0.8 cm/s, higher by a factor of about 10 than the value (mean: 0.12±0.09 cm/s; range: 0.06–0.28 cm/s) in the open area measured on the roof of our laboratory.
