of the oil soluble organic compounds high in carbon such as the sugars esters and the like glucose and succinate are particularly preferred the amount of the alternative source of carbon to be included in the medium may vary greatly but should be kept as low as possible to still support microbial activity e g 1 or less the temperature employed in the above process may vary over a considerable range in most cases the temperature will vary from about 20 u00b0 c to about 40 u00b0 c and preferably about 25 u00b0 c to 30 u00b0 c however higher or lower temperatures can be employed as needed since the process proceeds slowly under anaerobic conditions it is preferred to conduct the process under aerobic conditions the reaction medium is preferably stirred or shaken to speed the reaction as shown in the examples the reaction medium is preferably placed in a rotary shaker at speeds of about 200 rpm the length of the reaction may also vary depending upon the specific ingredients temperature etc in most cases the desired degradation of the nitrogen containing compounds can be accomplished in a matter of hours or days such as from 0 5 to 14 days the nitrogen containing compounds consumed in the reaction may be metabolized by the microbial population and thus appear as proteins in their composition.
