Slime-Forming Bacteria. Several forms of bacteria produce a slimy capsule under certain environmental conditions. These organisms are heterotrophic, that is, they obtain their energy from organic sources such as sodium lactate. The reaction is... 

These microorganisms become a problem when their numbers are large enough to produce corrosives such as carbon dioxide and hydrogen sulfide. Pseudomonas, Bacillus and Flavobacterium are examples of slime-forming bacteria. 

Natural waters may contain organic growths of various kinds, including algae and slime-forming bacteria, which may have a direct or indirect effect on corrosion.

Most slime-forming bacteria are aerobic. Species such as Pseudomonas produce an extracellular, gel-like, polysaccharide capsule which acts to protect and shield the organism. When in combination with other metabolic by-products, bacteria... 

Use For controlling slime-forming bacteria, sulfate-reducing bacteria, and algae in water cooling towers, air washers, pasteurizers, and other recirculation water systems. 

Hexachlorodimethylsulphone is a reactive microbicide which exhibits a broad spectrum of activity. The minimum inhibition concentrations for bacteria, fungi, yeasts and algae range between 10 and 100 mg/litre. The slime forming bacteria described by Kato Fukumura (1962) are especially sensitive to hexachlorodimethylsulphone MIC 0-5 mg/litre. In consequence of its limited stability in water the compound is mainly used as a non-persistent slimicide and algicide in process water circuits, e.g. in the paper industry, and not so much as a preservative. 

Slime-forming bacteria might cause clogging of pipes in production or inhomogenicity of the paint. Most often scraps of biofilms built up in the plant are responsible for these inhomogenicities in the products. 

These organisms are not the root eause of deposits, but their presence indicates inadequate treatment of incoming fresh water. If these organisms are present, the fresh water will likely serve as a souree of entry for slime-forming bacteria as well. Mills with good treatment programs may occasionally find microfauna in misted areas that do not come into contaet with biocides.
