金属加工液（MWF）自埃及人时代起就已在工业中使用，用于金属切削和磨削过程中的冷却和润滑。有几种类型，可以大致分为油基，半合成和合成。据估计，在5 × 109 L-1的区域在使用中，在欧盟（EU）在任何一个时间，他们在该地区的制造业成本的16%。MWF的微生物学由于两个相反的原因而受到关注，即：（1）它们代表微生物的有吸引力的营养源，这导致生物劣化，降低金属加工性能并可能导致人类病原体的入侵;（2）相比之下，潜在微生物定殖者的相同生物降解活性可以被利用和开发用于废液的生物处理。这些对比的微生物问题进行了讨论和提供的细节。需要进行研究，以开发新的MWF配方，是没有吸引力的微生物定植时，在使用中，但与一些化学修饰可以呈现易受微生物生物降解，当后续处置的废液是必需的，进行了讨论。
Metal working fluids (MWF) have been employed in industry since the time of the Egyptians, for cooling and lubrication during cutting and grinding of metal. There are several types, which can be broadly categorized as oil-based, semisynthetic, and synthetic. It is estimated that in the region of 5 × 109 L−1 are in use in the European Union (EU) at any one time,where they represent in the region of 16% of manufacturing industries costs. The microbiology of MWF is of interest for two contrasting reasons namely: (1) they represent attractive nutrient sources for microorganisms, which lead to bio-deterioration, reducing metal working performance and potentially leading to invasion of human pathogens; (2) in contrast, the same biodegradation activities of potential microbial colonizers can be harnessed and exploited for biotreatment of waste fluids. These contrasting microbiological issues are discussed and details provided. The need for research to develop new MWF formulations that are unattractive to microbial colonization when in use, but with a few chemical modifications can be rendered susceptible to microbial biodegradation, when subsequent disposal of waste fluids is required, is discussed.
