In the culture process of recombinant bacteria, a target gene carried on a plasmid is expressed only after a logarithmic phase begins but before a stable phase. A keratinase gene (ker) is expressed by utilizing the expression system,the thalli concentration and keratinase activityare improved by ...
1851); logarithmic phase Biol., the period during which the population of a culture of bacteria increases exponentially with time; logarithmic spiral, a spiral which intersects all its radiants at the same angle.1698J. Keill Exam. Th. Earth (1734) 243 The Applicate of the Logarithmick curve...
growth phaseLactobacillus gasseriimmunoelectron microscopyLipoteichoic acid (LTA) is a cell surface molecule specific to Gram-positive bacteria. How LTA localises on the cell surface is a fundamental issue in view of recognition and immunomodulation in hosts. In the present study, we examined LTA ...
The results from additional experiments revealed that the growth velocity seemed to be significantly related to the chain length of the bacteria, to growth patterns of the group B streptococci in fluid media and soft agar and to the surface hydrophobicity of the bacteria. Determination of growth ...
Methanogenic bacteriaThe ratios of tetraether to diether type lipids in the total lipid during cell growth in batch cultures of Methanobacterium thermoautotrophicum H (DSM 1053) were examined. The proportion of tetraether type lipids to the total lipid was about 80% during the log phase, and at...
Application of Mie theory and cubic splines to the representation of light scattering patterns from bacteria in the logarithmic growth phase. Phys Med Biol. 1979 Mar; 24 (2):408–415.Murray J, Hukins DWL, Evans P. Application of Mie theory and cubic splines to the representation of light ...
We found that, in both bacteria, its expression is not induced during the logarithmic phase of growth even in the presence of RhlR and C[sub 4]-HSL. Additionally, we found that rhlAB expression is partially 蟽[sup s] dependent.Medina...
Since we observed protein binding to the erp promoter DNAs in extracts of bacteria that expressed high levels of Erp proteins, this DNA binding protein(s) is more likely a transcriptional activator ...Indest, K. J., and M. T. Philipp. 2000. DNA-binding proteins possibly involved in ...
In the logarithmic phase (2-18 h), the number of bacteria has a steady geometric growth. Experimental Study on the Fine-Grained Uranium Tailings Reinforced by MICP The results in Figure S1 (in supplementary data) show that the growth rate of A, baumannii 34702 in xylose is slightly lower ...
