Influence of Polyethylene Glycol on the Size of Schizosaccharomyces pombe Electropores.

abstract：:To ascertain the health risks that may be posed by the land application of sewage sludges, a scheme was devised to determine the types and numbers of pathogenic and potentially pathogenic bacteria present in sludges. A processing treatment was adapted to sludge to give a homogenate which yielded the greatest numbers o...
