Methyl Sulfide Production by Aerobacter aerogenes in Milk

Naturally occurring levels of dimethyl sulfoxide in selected fruits, vegetables, grains, and beverages

“…The materials tested demonstrate that Me2SO and to a lesser extent Me2S02 are widely distributed in nature (see Table I). Most of the materials tested have been reported to contain Me2S (Tressl et al, 1977;Self et al, 1963;Miers, 1966;Dickenson, 1979;Toan et al, 1965;Kiribachi and Yamanishi, 1963). Therefore, it is not surprising that they would also contain Me2SO and Me2S02.…”

Methyl mercaptan and dimethyl disulfide production from methionine by Proteus species detected by head-space gas-liquid chromatography

“…Dimethyl sulfide has been reported as a microbial metabolic product (7,28). However, it was not detected by us as a breakdown product from methionine.…”

Formation of dimethyl sulphide from S‐methylmethionine in onion seedlings (Allium cepa)

“…In other cases MMS seems not to be involved in Me$ formation. [20][21][22] The role of MMS in plant sulphur intermediary metabolism has been considered by several authors. MMS is easily formed from methionine as demonstrated in oat seedlings,23 jack bean seedlings,24 tobacco plant,25 pumpkin, pea, kohlrabi and sesbania seedlings,26 onion and garlic,12 and apple fruit.,' MMS is formed from methionine and 5'-adenosylmethionine by cell-free extracts of jack bean roots2* and wheat germ acetone powder.29 Methionine is re-formed from MMS by a homocysteine transmethylase as demonstrated in oat seedlings,23 in extracts of dry seeds of several specie^,^',^^ as well as in pea c~l e o p t i l e s .~~ Enzymic splitting of MMS to Me$ and homoserine was demonstrated in cabbage leaf tissue'' and the present experiments with onion and other seedlings confirm this reaction but suggest it is only a minor pathway.…”
