Pseudomonas growth rate

The saturation constant for Saccharomyces cerevisiae on glucose is 25 mg/L, for Escherichia on lactose 20 mg/L, and for Pseudomonas on methanol 0,7 mg/L. Here, is the maximum growth rate achievable when... 

Biodegradation of 2,4-D is affected strongly by the pH value of the culture. At a pH of <5.1, there is extensive accumulation of its metabolite, 2,4-dichlorophenol, which inhibits the biodegradation completely (Sinton et al. 1987). The authors noted that biodegradation ceased completely when the concentration of the metabolite reached 44 mg/L. The highest growth rates (Pseudomonas sp. NCIB 9340) occurred at pH...

I have studied the toxicity of styrene and a number of other compounds by determining their effect on the growth rate of Rhodococcus S5 and Pseudomonas putida S12 (unpublished results). For both strains, the styrene concentration, that gave a 50% decrease in the growth rate with acetate as growth substrate, was about 180 mg/L The styrene-utilizing black yeast, Exophiala jeanselmei was much more sensitive towards styrene. In liquid culture, the maximum concentration that supported growth was 37 mg/l [7]. 

The styrene-utilizing Pseudomonas putida S12 initially could not grow in the presence of supersaturating amounts of styrene (1% v/v). However, after incubation for 20 h under these conditions, the culture started to evolve CO [8]. When cells grown under these conditions wctc used to inoculate medium with 1% or 0.008% (v/v) styrene, no lag phase was observed and the growth rate in both cultures was the same (0.6 h ). This adaptation to hi styrene concentrations is probably a result of an alteration in the membrane composition.
