Densities ofAeromonas hydrophila were determined monthly from December 1975 to December 1977 in a South Carolina cooling reservoir which receives heated effluent from a single nuclear production reactor. Selected water quality parameters an...
Cellulolytic bacteria as primary colonizers ofPotamogeton pectinatus L. (Sago Pond Weed) from a Brackish South-Temperate Coastal Lake [0.03%]

Bacteria adhering to newly emerged and decomposing leaves ofPotamogeton pectinatus L. were examined using scanning electron microscopy. Bacteria obtained from mature leaves were isolated, grown in pure culture, and allowed to infect bacteri...

The marine chrysophyteMonochrysis lutheri was grown in phosphorus-limited continuous cultures at temperatures of 15°, 18.8° and 23°C. The effect of temperature on the maximum growth rate was well-defined by the Arrhenius equation, but th...

Cu(2+) ion determinations were carried out in complex and in inorganic salts-glycerol media, to which increasing amounts of Cu(II) had been added, with the ion-specific Cu(II)-Selectrode. Likewise, complexing capacity of bacterial suspensio...

Adenosine triphosphate in soil is measured by the luciferin-luciferase bioluminescence method. Cation exchange in the ATP extraction procedure is used to reduce the content of, e.g., Fe, Al, and Cations in extracts. The efficiency of the ca...
An indirect fluorescent antibody staining technique for determining population levels ofThiobacillus ferrooxidans in acid mine drainage waters [0.03%]
一种间接荧光抗体染色技术用于测定酸性矿山排水中硫化叶菌的数量水平

Thiobacillus ferrooxidans is believed to be responsible for the oxidation of ferrous ion at low pH, the rate-limiting step in the oxidation of pyrite ores and subsequent formation of acid mine drainage (AMD). It has been suggested that effo...

Thioploca had been encountered in several locations in Central Europe. Five of these were revisited to find out ifT. schmidlei andT. ingrica were still present in these locations. Of the three locations in Lake Constance with abundant popul...
A comparison of oxygen, nitrate, and sulfate respiration in coastal marine sediments [0.03%]

The rate of glucose decomposition and the pH fell in a forest soil (initial pH 4.06) exposed to 1.0 ppm SO2. No such effect was noted if the soil was exposed to 1.0 ppm nitrogen dioxide (NO2). Nitrite but not bisulfite (5μg N or S/g of soi...
