Furthermore, crvA is quorum regulated, and CrvA-dependent curvature increases at high cell density.
The high cell density allows a reduction of harvesting cost.
Both phenotypes suggest that downregulation of O1 antigen phage receptor occurs in response to autoinducers and thus at high cell density.
Enteric bacterial pathogens including V. cholerae are known to colonize and multiply in the intestine, and thus exist in a high cell density state.
Romer, P. S. et al. Preculture of PBMCs at high cell density increases sensitivity of T-cell responses, revealing cytokine release by CD28 superagonist TGN1412.
However, bacteria in the environment frequently populate microbial communities called biofilms14,15, in which they exist in a state of high cell density.
Muller, C., Laurent, G. & Ling, V. P-glycoprotein stability is affected by serum deprivation and high cell density in multidrug-resistant cells.
Through high cell density fermentation, the expression level of mRmMan5A reached 79,680 U mL−1.
Producing proper nutrient supply, uniform cell distribution and high cell density are the important challenges.
These devices show fast write and read speeds, high cell density, and allow nonvolatile operation.
High cell density fermentation through immobilization and cell-recycling techniques are also addressed.
