characteristics of klebsiella from textile finishing plant effluents. / reprint: characteristics of klebsiella from textile finishing plant effluents

a survey of bacteria in a stream receiving wastes from a textile finishing plant revealed an abnormally high number of klebsiella in the absence of any source of fecal pollution. the density at times reached as high as 1 x 10000000 cells per milli-liter. since this genus constitutes a part of the coliform group that is used as an index of..
