Technical Bulletin No. 0098: Identification and Environmental Factors Favoring Growth of Organisms Responsible for River Slime Infestations

Simultaneous to the preparation of the critical review of the literature on river slimes, by the Rutgers University Project of the National Council, reported in Technical Bulletin No. 98, samples of slime from several rivers were examined. The physical and chemical conditions attending their growth were recorded for streams typical of the far northern, central, and southern sections of the country receiving pulping effluents. These investigations are reported in the attached Technical Bulletin. Results of these examinations reveal that two organisms, similar in character, are involved. This observation has since been verified from samples taken at other locations and simplifies future studies which will deal with the physiology and nutrition of these organisms. It is hoped that such knowledge will lead to a method for controlling these growths.
