The Biochemistry of Anaerobiosis
To live anaerobically an organism must generate its energy and synthesize its substance without recourse to molecular 02. Thus any discussion of the biochemistry of anaerobiosis must centre on what alternatives there are to aerobic respiration and oxygenic photosynthesis as means of biological energy conservation, and to what extent an anaerobe is constrained by being denied the facility of exp...
متن کاملSimple and Economical Method for the Preparation of MgO Nanostructures with Suitable Surface Area
A facile and simple method was proposed to control the size and shape of the MgO nano structures with high surface area in the presence of efficient and cheap templates like PEG 200, PEG 600, PEG 4000 and sorbitol at low temperature within a little time. Nano rods and Nanoparticles have been achieved by applying these templates and altering other growth parameters. The products were charact...
متن کاملStreptomycin Action and Anaerobiosis.
The question was asked whether the insensitivity to dihydrostreptomycin and streptomycin exhibited by facultatively anaerobic organisms growing strictly anaerobically could be due entirely to the lack of an anaerobic mechanism for the uptake of these antibiotics. A technique is described here which allows exposure of Escherichia coli B to dihydrostreptomycin, under conditions which are known to...
متن کاملEconomical Numbers
A number n is said to be economical if the prime power factori-sation of n can be written with no more digits than n itself. We show that under a plausible hypothesis, related to the twin prime conjecture, there are arbitrarily long sequences of consecutive economial numbers, and exhibit such a sequence of length 9.
متن کاملSimple, efficient and economical methods for isolation and estimation of novel isoflavone using RP-HPLC
The study was undertaken to develop a simplified procedure for the isolation of bioactive isoflavone from Iris kashmiriana, using a direct method of isolation, avoiding the use of chromatographic techniques. The compound was isolated by commercially viable procedure. The extraction of powdered drug (500 g) was done with petroleum ether (60-80) using a Soxhlet apparatus (24 h run). The petroleum...
