A method of producing chemicals includes providing fermentative cells; co-feeding any of galacturonate and galacturonate polymers with carbohydrates to the fermentative cells; and producing a chemical from the fermentative cells. The fermentative cells may include any ofand. The carbohydrates may include any of glucose, mannose, galactose, fructose, arabinose, xylose, sucrose, lactose, maltose, cellobiose, and starch. The method may include providing a substantially equal proportion of the any of galacturonate and galacturonate polymers and the carbohydrates for co-feeding to the fermentative cells. The method may include altering a proportion of the any of galacturonate and galacturonate polymers to the carbohydrates. The method may include modulating a production of the chemical by altering the proportion of the any of galacturonate and galacturonate polymers to the carbohydrates. The chemical may include any of acetate and butyrate.

Use of galacturonate and or galacturonate polymers in conjunction with carbohydrates to control metabolic state of organisms

A method for increasing susceptibility of microorganisms to antibiotics includes providing a microorganism; administering an antibiotic including a nitro-containing amphenicol compound to the microorganism; and administering any of an uronic, aldonic, ulosonic, and aldaric feedstock to the microorganism. The feedstock is adapted to promote cell metabolism, and inhibit antibiotic inactivation pathways in the microorganism causing increased sensitivity of the microorganism to the nitro-containing amphenicol.
