The study of the growth of bacterial cultures does not consti­ tute a specialized subject or branch of research: it is the basic method of Microbiology. It would be a foolish enterprise, and doomed to failure, to attempt reviewing briefly a "subject" which covers actually our whole discipline. Unless, of course, we considered the formal laws of growth for their own sake, an ap­ proach which has...

conclusions bacterial resistance against quaternary ammonium compounds is increasing which can increase the bacterial biofilm formation. results the means of strains growth increase after the minimal inhibitory concentration (mic) were significant in all the bacteria (except for e. coli in 1/32 and s. agalactiae in of 1/8 mic). biofilm formation increased with decrease of antiseptics concentrat...

b a s e don folic acid biosynthetic pathway a mathematical model was made for bacterial growth to describe the synergistic effect between sulfamethoxazole and trimethoprim. The results obtained show a strong synergism at growth inhibiting concentrations of these two drugs. Two cyclic pathways included in the model are responsible for this synergism. The roles of these pathways in producing ...

A detailed understanding of the influence of temperature on soil microbial activity is critical to predict future atmospheric CO2 concentrations and feedbacks to anthropogenic warming. We investigated soils exposed to 3-4 years of continuous 5 °C-warming in a field experiment in a temperate forest. We found that an index for the temperature adaptation of the microbial community, Tmin for bacter...

in order to study the effects of seed-bacterial priming (inoculation) on germination and early growth of alfalfa under salinity stress conditions, an experiment was conducted at seed research laboratory and greenhouse of college of agriculture, university of tehran in karaj (iran) in 2011. the experiment was arranged as a factorial in completely randomized design (crd) with three replications. ...
