BIOPRODUCTION OF CITRIC ACID FROM
INDUSTRIAL BY-PRODUCTS
Its low cost, high carbohydrate content and high
susceptibility to fermentation make the processing of citrus byproducts
an attractive, environmentally-friendly, alternative
way for the biotechnological production of chemicals (23).
The recombinant strain Escherichia coli KO11 was shown
to ferment arabinose and galacturonic acid obtained from
enzymatic hydrolysates of orange peel to acetic acid, ethanol,
carbon dioxide and small amounts of lactic acid (10, 72). Due
