Mineralization of metsulfuron-methyl in Chinese paddy soils.
A laboratory study was conducted to investigate the mineralization of metsulfuron-methyl (MSM) in paddy soils in response to soil moisture, temperature and soil properties. The results indicated that MSM mineralization was relatively limited in the paddy soils when soil temperature was low. Only 2.2-6.0% of the applied (14)C mineralized after 84d of incubation at 15 degrees C. The mineralizatio...
متن کاملResidues of 14C-metsulfuron-methyl in Chinese paddy soils.
BACKGROUND Metsulfuron-methyl is widely used for controlling many annual grasses and broadleaf weeds in cereal crops. Nonetheless, increasing evidence has demonstrated that even extremely low levels of metsulfuron-methyl residues in soil can be toxic to subsequent crops or non-target organisms. The behavior of herbicides in soils is mostly related to their residual forms. The intent of the pres...
متن کاملFormation of methyl mercaptan from L-methionine by Porphyromonas gingivalis.
Methyl mercaptan production by oral bacteria is thought to be one of the main causes of oral malodor. We examined the ability of periodontopathic Porphyromonas gingivalis to produce methyl mercaptan from L-methionine and found that the invasive strains W83 and W50 produced large amounts of methyl mercaptan. We cloned and sequenced the mgl gene encoding L-methionine-alpha-deamino-gamma-mercaptom...
متن کاملagainst Methyl Mercaptan
The deodorizing mechanism of (-)-epigallocatechin gallate (ECCg), the main constituent of a green tea extract, against methyl mercaptan (CH,SH) was investigated. EGCg showed deodorizing activity against CH3SH by a chemica] reaction between EGCg and CH3SH. The non-volatile reaction products were identified to be compounds introducing a methylthio andlor a methylsulfinyl group into the B ring of ...
