Vegetative Cells and Microcysts of Myxococcus xanthus
A number of reports have demonstrated that microcysts, the resting cells produced by most myxobacteria, are more resistant than the corresponding vegetative cells. Baur (1) showed that mycrocysts of Myxococcus ruber withstood desiccation and wet and dry heat better than did vegetative cells. In 1936, Imshenetsky and Solnetzewa (6) reported comparable findings for Cytophaga hutchinsonil and C. e...
متن کاملEffect of temperature on the growth of Myxococcus xanthus.
The cardinal growth characteristics of Myxococcus xanthus were examined from 14 to 40 degree C, and the examinations indicated that the organism is mesophilic in character. The maximum growth rate (0,3 doublings per h) was between 34 and 36 degree C and the temperature characteristic (micron) is 17,000 cal/mol (71,162 J/mol).
متن کاملStraight-chain fatty acids are dispensable in the myxobacterium Myxococcus xanthus for vegetative growth and fruiting body formation.
Inactivation of the MXAN_0853 gene blocked the production in Myxococcus xanthus of straight-chain fatty acids which otherwise represent 30% of total fatty acids. Despite this drastic change in the fatty acid profile, no change in phenotype could be observed, which contrasts with previous interpretations of the role of straight-chain fatty acids in the organism's development.
متن کاملCell density-dependent growth of Myxococcus xanthus on casein.
When Myxococcus xanthus FB was grown on 0.2% casein it exhibited a phenomenon we call cooperative growth. That is, above 104 cells per ml, both strains that were studied exhibited increasing growth rates as a function of increasing cell numbers. Between 104 and 107 cells per ml, the mean doubling times of strains YS and TNS decreased from 15.2 to 8 h and 26 to 8.5 h, respectively. The extracell...
متن کاملComparative intermediary metabolism of vegetative cells and microcysts of Myxococcus xanthus.
Crude extracts of both vegetative cells and glycerol-induced microcysts of Myxococcus xanthus contained the following enzyme activities: phosphofructokinase, phosphoglucoisomerase, fructose-1,6-diphosphatase, fructosediphosphate aldolase, glyceraldehyde-3-phosphate dehydrogenase, phosphopyruvate carboxylase, citrate synthase, isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, succinat...
