The effects of organic and inorganic sources on the growth of Anabaena sphaaerica HB 1017 are studied. The result shows that in organic carbon sources, the most effective concentrations of glucose and sucrose are 0.5—1.0μg/mL and 5.0 μg/mL respectively; while in the inorganic carbon soureces, the most effective concentrations of sodium carbonat and bicarbonat are 10.0—15.0 μg/mL and 10.0μg/mL respectively. The concentration of glucose or sucrose have no influence on the chlorophyll, a,...

The concentration of glucose or sucrose have no influence on the chlorophyll, a, but A. sphaerica HB 1017 bit a little more chlorophyll a when cultured in medium containing glucose than in containing sucrose. Both soureess carbonate and bicarbonate raise chlorophyU_a at the concentration of 5.0μg/mL. All of the four carbon sources can enhance the nitrogen-fixing ability of A. sphaerica HB 1017, but in the organic carbon sources, sucrose has greater effect than glucose; while in the inorganic carbon sources, the effect of sodium carbonate is greater than that of sodium bicarbonate.

本文研究了有机碳源和无机碳源对球胞鱼腥藻生长的影响,结果表明:有机碳源中葡萄糖以0.5—1.0μg/mL、蔗糖以5.0μg/mL促进其生长效果最好;无机碳源中,碳酸钠以10.0—15.0μg/mL、碳酸氢钠以10.0μg/mL效果最好。葡萄糖和蔗糖的浓度高低对球孢鱼腥藻叶绿素a的含量没有明显影响,但前者略高于后者。碳酸钠和碳酸氢钠的浓度在5.0μg/mL时均提高了叶绿素a含量。四种碳源都提高了球孢鱼腥藻的同氮活性,有机碳源中蔗糖优于葡萄塘,无机碳源中碳酸钠优于碳酸氢钠。

Under selective culture conditions, two pure cultures (strain G and strain SG) of the purple nonsulfur photosynthetic bacteria containing bacteriochlorophyll b were isolated from pulp effluent and sludge of sewage treatment plant by means of agar shake dilution. Although the cells of strain G and strain SG contained bacteriochlorophyll b and carotenoids, intra-cytoplasmic membranes were of lamellar type parallel to cytoplasmic membrane, the two strains differ in using various organic carbon sources, depending on reduced sulfur compounds and assimilate sulfate. According to Bergey's Manual of Systematic Bacteriology Volume 3, strain G was identified to be Rhodopseudomonas viridis, , strain SG was identifided to be Rhodopseudomonas sulfoviridis.

Two sediment cores (W,B and E,B) from Taihu Lake were analyzed for their deltacarbon isotopes("C/"C).W,B was collected from West Taihu Lake, while E,B was fromEast Taihu Lake. Of fifteen samples determined for East Taihu Lake, the average valuefrom Z17cm (e. g. 16 000 aB.P.)is-22.76, the average value between depths of200-90 cm (e.g.,6 500-6 000 aB. P. )is-27.07 and the average value from 90cmsurface (e.g.6 000 aB. P.to present) is-22. 87. As for the fifteen samples determinedfor West Taihu Lake, the average value between depths of 280 and 70 cm (e. g. 11 0006 000 aB. P.)is-23.94,and from 70cm-surface(e.g.,6 000 aB.P.to present)is~23.55.Comparing the a 13C values before and after 6 000 aB. P. between West Taihu Lakeand East Taihu Lake,we found that the values are lower in the period before 6 000 aB. P.as compared to the years after 6 000 aB.P.The lower values correspond to the higher average regional temperatures, while the higher values correlated to the lower average regional temperatures. When comparing the 8 13C values between West Taihu Lake and EastTaihu Lake,we found that the 6 13C values from West Taihu Lake are much higher thanthe values obtained from East Taihu Lake. This difference may be attributed to the organic carbon sources.The low 8 13C values obtained from East Taihu Lake prior to 6 000 aB.P.could be due to the heterotrophic carbon source from the watershed.This is likely toreflect running water environments such as rivers or streams,while the much higher 8 13Cvalues from West Taihu Lake are likely to indicate autotrophic carbon sources, reflecting alacustrine environment.This also shows that the western part of Taihu Lake was in a lacustrine environment about 11 000 aB.P.,earlier than East Taihu Lake. East Taihu Lakeprior to 6 000 aB.P.has been shown to have been a running water environment with asubstantial proportion of organic carbon input from the watershed.It became a lacustrineenvironment after 6 000 aB.P.

通过太湖两个钻孔岩芯有机碳同位素(13C/12C)的分析,发现δ13C的垂直分布与太湖地区16000aB.P.以来古气候波动相关。根据δ13C垂直分布曲线可推测,大约在11000—6000aB.P,太湖地区处于温暖湿润期,气温高于现在平均温度。另一方面,根据太湖两岩芯沉积物的δ13C值的对比发现,大约在11000—6000aB.P,西太湖(W1B)岩芯沉积物的δ13C平均值明显高于东太湖(E2B)。据此可认为,在这一期间西太湖很可能有过海水侵入。
