Ethanol Production and Utilization by Aphelenchus avenae and Caenorhabditis sp.
Abstract
In microaerobic and anaerobic environments the principal glycolytic end-product of A. avenae and Caenorhabditis sp. was lactic acid during the first 12-16 hr, after which it was ethanol. Upon return to aerobiosis,¹[sup4]C-labeled ethanol in the medium was utilized by the nematodes;¹[sup4]CO[sub2] and some¹[sup4]C-labeled glycogen was detected. Total dry weight loss of non-feeding nematodes was 25% greater in the absence of alcohol than in the presence of ethanol or n-propanol. Physical movement and respiration increased and reproduction was extended by alcohol in the bathing solution. Key Words: Lactic acid, Acetaldehyde, Succinic acid, Aerobic, Anaerobic, Microaerobic, Glycolysis, Alcohol dehydrogenase, Lactic dehydrogenase.Downloads
