Nalidixic acid kills only growing cells of Salmonella typhimurium and can be used to enrich for auxotrophs in populations where prototrophs predominate.
Nadilidixic acid at 5 x 10(-6) M produced a substantial increase in thermal susceptibility of Ts-7, suggesting either that the thermal and nalidixic acid targets are identical or closely interdependent.
Possible Formation of Dehydro-L-ascorbic Acid from 2,3-Diketo-L-gulonic Acid in an Aqueous Solution.
The reaction of 2,3-diketo-L-gulonic acid (DKG), which is one of the important intermediate products in the degradation of L-ascorbic acid (ASA) in both food and biological systems, in an aqueous solution was studied. The formation of a small amount of the γ-lactone, dehydro-L-ascorbic acid (DASA), from DKG was observed. This strongly suggests the chemical possibility of a reverse reaction in D...
In the title 1:1 adduct, C(7)H(5)NO(4)·C(7)H(7)NO(2), the nitro group of the 4-nitro benzoic acid is twisted from the attached ring by 4.40 (8)°. In the crystal, the mol-ecules are linked into ribbon-like structures along [150] and [10] via O-H⋯O, N-H⋯O, N-H⋯N and C-H⋯O inter-molecular hydrogen bonds.
