Summary Methionine, up to 10−3 M, added to a basal medium enhanced bacterial ethylene production in 14 of the 20 bacteria tested. The effects of substrate, cofactors, light, and temperature on ethylene production byPseudomonas solanacearum #25 revealed that the greatest effect occurred when 10−5 M methionine and 10−4 M FMN were combined, from which 4.10μl/l of ethylene were produced. Higher levels of methionine resulted in production of high levels of non-enzymically produced ethylene and death of the bacteria. This non-enzymic production of ethylene was eliminated in the dark. Copper had no effect upon ethylene production. Twenty-nine and 35°C were inhibitory, whereas 19°C appeared to be near optimum for ethylene production.Pseudomonas solanacaerum #25 and some other bacteria are capable of ethylene production and methionine and FMN enhance this production.
