EXAMPLE - Media solution (comprising Clostridium autoethanogenum, ammonium acetate (3.083 g), magnesium dichloride hexahydrate (0.61 g), calcium chloride dihydrate (0.294 g), potassium chloride (0.15 g), sodium chloride (0.12 g) and distilled water (balance)) (1.4 l) was aseptically and anaerobically transferred into a vessel (2 l), and continuously sparged with nitrogen and transferred to the fermentation vessel. The media was heated to 37 degrees C and stirred at 400 rpm and resazurin (1.5 ml) was added, then phosphoric acid (1 ml) was added to obtain a 10mM solution. The pH was adjusted to 5.3 using ammonium hydroxide. Then solution comprising (ferric chloride (1 ml), cobalt(II) chloride (0.5 ml), nickel(II) chloride (0.5 ml), boric acid (0.1 ml), sodium tungstate (0.1 ml), zinc chloride (0.1 ml) and sodium molybdate (0.1 ml)) and solution (comprising biotin (20 mg), folic acid (20 mg), vitamin B12 (50 mg), pyridoxine hydrochloride (10 mg), p-aminobenzoic acid (50 mg), thiamine hydrochloride(50 mg), thioctic acid (50 mg), riboflavin (50 mg), nicotinic acid (50 mg), calcium D-pantothenate (50 mg) and distilled water (balance)) (15ml) were added. Cysteine-hydrochloride (3 mM) was added and the pH was adjusted to pH 5.5 using ammonium hydroxide and incubated for 1.8 days to obtain acetate (1.49 g/l) and ethanol (0.45 g/l).
