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.

Polymeric substance and method of separating and culturing bacteria

J-1 which is a strain of cyanobacteria is used to form and excrete a material useful as a floculating agent and as an additive useful in soil conditioning. Method of separating and culturing the cyanobacteria under conditions necessary to achieve maximum formation and excretion of the material into solution. Method of purifying and separating excreted as well as intracellular material from cyanobacterial. Method of clarifying a particulate-laden liquid with a material excreted by cyanobacteria, and particularly species J-1.
