Microbial degradation of polycyclic aromatic hydrocarbons: effect of substrate availability on bacterial growth kinetics
SummaryIt is demonstrated that bacterial growth on crystalline or adsorbed polycyclic aromatic hydrocarbons can result in a linear increase in biomass concentration. A simple mathematical approach isExpand

Properties of the Cell Walls of Lactococcus lactis subsp. cremoris SK110 and SK112 and Their Relation to Bacteriophage Resistance.
Resistance of Lactococcus lactis subsp. cremoris SK110 to bacteriophage sk11G, encoded on the plasmid pSK112, is due to poor phage adsorption. Its phage-sensitive variant SK112, cured of pSK112,Expand

Influence of nutrient limitation and growth rate on the outer membrane proteins of Klebsiella aerogenes NCTC 418.
Four major proteins with molecular weights of 78 000, 37 000, 34 000 and 20 000 were present in the envelope of Klebsiella aerogenes when cultured at a high specific growth rate. However, at lowerExpand

Influence of specific growth limitation and dilution rate on the phosphorylation efficiency and cytochrome content of mitochondria of Candida utilis NCYC 321
With Candida utilis cells that had been removed directly from a 61 chemostat culture, in steady state, well-coupled mitochondria generally could be isolated. This required a modified snail-gut enzymeExpand

Loss of phage resistance encoded by plasmid pSK112 in chemostat cultures of Lactococcus lactis ssp. cremoris SK110.
In cultures of L. lactis ssp. cremoris SK110, phage SK11G-resistant through the presence of pSK112, phage-sensitive variants segregated spontaneously that lacked the plasmid. In overnight batchExpand

Phenotypic variability of the sensitivity to cycloserine of Klebsiella aerogenes NCTC 418, growing in chemostat culture.
The susceptibility of Klebsiella aerogenes to cycloserine varied according to the growth conditions. In batch culture, cells were less susceptible to the antibiotic when glycine was present in theExpand

Effect of iron limitation on the cell envelope ofKlebsiella aerogenes NCTC 418
Since in natural habitats the free iron concentration is generally low, the effect of iron limitation on the sensitivity of Klebsietla aerogenes to penicillin G (pen G) was studied. Also, theExpand

Expression and loss of the pBR322 plasmid in Klebsiella aerogenes NCTC 418, grown in chemostat culture
Klebsiella aerogenes harbouring the plasmid pBR322 was grown in continuous culture at various growth rates under glucose, phosphate or ammonia limitation. With tetracycline in the medium, the maximumExpand
