||Microbial and endotoxin contamination of water-soluble metalworking fluids
||4th Quarter 2007, Vol.20, No.4, p.365-371. Illus. 23 ref.
||The aim of this study was to evaluate the level of microbial contamination of metalworking fluids as a potential source of harmful biological agents in three metalworking plants in Poland. Ten samples of fluids, including four fresh fluids, were analyzed. The analysis showed total bacterial counts ranging from 1.0x101 to 3.2x107 CFU/mL, 60% to 100% of which were Gram-negative bacteria capable of producing endotoxins. The predominant species of bacteria was Shewanella putrefaciens present in 60% of the samples. As for moulds, the predominant species was Acremonium butyric. The average concentration of bacterial endotoxins was 773 EU/mL in used fluids and 285 EU/mL in fresh fluids. A correlation was found between endotoxin concentration and the number of Gram-negative bacteria detected in the fluids. Other findings are discussed.
