Thermoanaerobacter finnii spec. nov., a New Ethanologenic Sporogenous Bacterium
A strain of a strictly anaerobic, thermophilic eubacterium (AKO-1) was isolated from a consortium converting acetic acid to methane at 60 °C and revealed that the organism was closely related to the non-sporeformer Thermoanaerobacter ethanolicus, however the ability to form heat resistant spores and the lack of an inner and outer cell wall layer separated the new isolate from T. ethanolicsus.

Occurrence and the possible physiological role of 2‐enoate reductases
A purified enoate reductase from Clostridium kluyveri is reported and the occurrence of such an activity in the typical amino acid fermenting species Clostridgeium sporogenes is reported. Expand
On the formation of 3‐phenylpropionate and the different stereo‐chemical course of the reduction of cinnamate by Clostridium sporogenes and Peptostreptococcus anaerobius
An oxidative and a reductive branch to explain the above-mentioned products are suggested and the capability of resting cells of C. sporogenes as well as Peptostreptococcus anaerobius to convert L-phenylalanine, (2R)-phenyllactate, phenylpyruvate and cinnamate to 3- phenylpropionate is compared.

On the occurrence of enoate reductase and 2-oxo-carboxylate reductase in clostridia and some observations on the amino acid fermentation by Peptostreptococcus anaerobius
Enoates as well as 2-oxo-carboxylates are intermediates of the pathway by which amino acids are degraded, and an explanation is offered for the long known but not understood fact that in the Stickland reaction isoleucine always acts as an electron donor and leucine and phenylalanine can be electron acceptors as as donors.
