The products of anaerobic and micro‐aerobic (0.8% O 2 ) metabolism of the sapropelic ciliate Trimyema compressum strain N were studied. Under anaerobic conditions ethanol was formed in large amounts representing 44% of the total carbon excreted. Acetate, lactate, formate, CO 2 and H 2 were minor products, while succinate was formed in hardly detectable amounts. Under micro‐aerobic conditions O 2 was consumed, CO 2 and formate were produced as major end products and no H 2 , ethanol and succinate were formed.
