Abstract
Abstract A process for treating soluble biodegradable organic waste material which comprises: A. preparing a reaction mixture of soluble biodegradable organic waste material and a thermophilic aerobic microorganism culture capable of digesting such soluble material and containing soluble sources of manganese, magnesium, phosphorus, iron and nitrogen in a liquid medium and at a pH ranging from about 5.5 to 9, the soluble organic material content being in excess of 1 gram per liter, B. introducing oxygen into the mixture so as to maintain the dissolved oxygen content at least 0.01 mg per liter of said mixture while C. maintaining said mixture at a temperature of from 45° to 70°C for a time sufficient to convert the organic waste material into cellular proteinaceous material, and D. separating the cellular proteinaceous material produced.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
136 words
A process for treating soluble biodegradable organic waste material which comprises: a. preparing a reaction mixture consisting essentially of soluble biodegradable organic waste material and a microorganism culture consisting of thermophilic aerobic bacteria capable of digesting such soluble material and containing soluble sources of manganese, magnesium, phosphorus, iron and nitrogen in a liquid medium at a pH ranging from about 5.5 to 9, the soluble organic material content being in excess of 1 gram per liter; b. introducing an oxygenating gas into the mixture so as to maintain the dissolved oxygen content at least 0.01 mg per liter of said mixture while c. maintaining said mixture at a temperature of from 45° to 70°C for a time sufficient to convert the organic waste material into cellular proteinaceous material, and d. separating the cellular proteinaceous material produced.
Claim 2
