✦ Synopsis

The effects of growing Clostridiurn acetobutylicurn NCIB 8052 in a chemostat under conditions of glucose, NH,', PO$-, Mg2+, and Fez+ limitation were examined. It was noted that limitation of any major nutrient resulted in the same fermentation pattern. Conditions where minor nutrient levels were reduced appeared to stimulate solvent production. Under conditions of Mg2+ restriction, a productive solventogenic culture was produced, with a yield of total solvents on glucose of 35.5%.

Pseudomonas aeruginosa 142 and a presumed variant were grown axenically in chemostats on salicylate/benzoate or salicylate/glucose binary feeds. Each substrate was supplied at 2, 10, 50, 90, 98, or 100% of the total energy flux. Two experiments were also run with ternary mixtures using the same subs
