25. Reductive dehalogenation of halocarboxylic acids by the phototrophic genera Rhodospirillum and Rhodopseudomonas.
Type strains of the purple nonsulfur species Rhodospirillum rubrum, Rhodospirillum photometricum, and Rhodopseudomonas palustris grew phototrophically on a number of two- and three-carbon halocarboxylic acids in the presence of CO2, by reductive dehalogenation and assimilation of the resulting acid. Strains of each of these species were able to grow on chlor

26. Microbial Population of Feedlot Waste and Associated Sites
A quantitative determination was made every 2 months for a year of the microflora of beef cattle waste and runoff at a medium-sized midwestern feedlot. Counts were obtained for selected groups of organisms in waste taken from paved areas of pens cleaned daily and, therefore, reflect the flora of raw waste. Overall, in terms of viable count per gram dry weigh

27. Anaerobic versus Aerobic Degradation of Dimethyl Sulfide and Methanethiol in Anoxic Freshwater Sediments
Degradation of dimethyl sulfide and methanethiol in slurries prepared from sediments of minerotrophic peatland ditches were studied under various conditions. Maximal aerobic dimethyl sulfide-degrading capacities (4.95 nmol per ml of sediment slurry · h−1), measured in bottles shaken under an air atmosphere, were 10-fold higher than the maximal anaerobic d
