PMA to degrade 4C2NP in the soil, we performed microcosm studies using both sterile and non-sterile soils under optimized conditions. The optimized parameters were as follows: inoculum size 2 × 107 CFU g−1 soil, pH 7.5, temperature 30°C, and substrate concentration 100 ppm ...
A hallmark of the Leg biosynthesis pathway is the presence of the LegX enzyme, which is required for the conversion of the uridine diphosphate-linked N-acetylglucosamine (UDP-GlcNAc) to guanosine diphosphate (GDP)-GlcNAc, the starting point for Leg biosynthesis.6 In fact, L2745_04770, the S...
derivative for which R1 is a chlorine, bromine or iodine atom or an azido or thiocyanato radical and R′1 is a hydrogen atom, and/or followed by the conversion of a streptogramin derivative of general formula (I) for which the bond- - -is a double bond into a streptogramin ...
The presence of a methylene group bearing the chlorine atom at the side chain was confirmed by the presence of a multiplet at 4.03–4.11 ppm, which corresponds to the signal at 44.6 ppm in the 13C-NMR spectrum. Finally, the signals at δ 6.57, 7.29 and 7.64 in the 1H-NMR spectrum ...
6) In order that the above conversion of one compound to another may be accomplished, the chemical properties of each compound must be understood. 为使上述转化(由一种物质转化成另一种物质)能够实现,必须了解每一种物质的化学性质。 7) Again, the solution of this problem would be impossible were...
