ABSTRACT:
J-1 which is a strain of cyanobacteria is used to form and excrete a material useful as an emulsifying agent for forming emulsions of hydrocarbons and oils in liquids such as water.
Method of separating and culturing the cyanobacteria under conditions necessary to achieve a maximum formation and excretion of the emulsifying agent into solution.
Method of purifying and separating excreted as well as intracellular material from cyanobacteria.
Method of removing stains with a material excreted by cyanobacteria, and particularly strain J-1.
Method of effecting the secondary recovery of petroleum through the use of a material excreted by cyanobacteria, and particularly strain J-1.
Extracellular polymeric material which is greater than 200,000 Daltons in molecular weight, and contains sugar, fatty acid, and protein moieties, and amide, carboxylic and amino groups.
