Klm. Buers et al., THE ABILITY OF SELECTED BACTERIAL ISOLATES TO UTILIZE COMPONENTS OF SYNTHETIC METAL-WORKING FLUIDS AS SOLE SOURCES OF CARBON AND NITROGEN FOR GROWTH, Biotechnology letters, 19(8), 1997, pp. 791-794
A total of 24 bacterial isolates able to grow on metal-working fluids
were obtained from soil or metal-working fluids (both in-use and heavi
ly contaminated fluids). Pure cultures of the isolates were tested for
their ability to degrade a selection of components, including berate
esters, phosphate ester, biocide and triethanolamine, typically found
in synthetic metal-working fluids. All components, when present at a l
evel equivalent to half that found in an in-use metal-working fluid, s
upported growth when utilised as the sole source of carbon and/or nitr
ogen. Each component was degraded by at least 50% by an individual iso
late within 120 hours in batch liquid culture.
