Additionally, total cell count by flow cytometry was also used as a proxy for cell number and generated similar results to the ones collected by normalizing through OD as a proxy for cell count (Supplementary Fig. 1). c OD-normalized fluorescence 24 h after a 1-hour induction at 37 ...
Bacteria consist of only a single cell. Additionally, bacteria are prokaryotes, which means their single cell does not have a nucleus like an animal or plant cell does. Instead, their genetic material (DNA) just floats around inside the cell. Bacteria often have a single loop of DNA and pos...
34,35, Concanavalin36, antibodies37, boronic acid38, and enzyme-activated nanoparticles39. However, the payloads of signaling agent on bacterial cell wall are relatively lower than those internalized into intracellular volume of bacteria, leading to a lower sensitivity. In...
However, whereas antibiotic treatment suppressed the mRNA expression of two important intestinal progenitor/stem cell markers, Olfm4 and Lgr5, PHY906 treatment resulted in enhanced expression of these two stem cell markers. Conclusions Alterations in the population of intestinal bacteria did not affect...
How bacteria talk to each other: regulation of gene expression by quorum sensing Bonnie LBassler, inCurrent Opinion in Microbiology, 1999 There exist a number of processes inGram-positive bacteriathat are responsive to cell population density. Among these are competence for DNA uptake inBacillus subt...
that are specific to surface/flagellin proteins of the bacterial or the bacterialwhole cell, are also used to detect the presence of bacteria. These probes are often applied in biosensors for the detection of specific types of bacteria. This review provides an overview of the currently availableba...
Knowing that bile acids can control the expression of CXCL16, the investigators treated mice with bile acids, so they changed the number of NKT cells in the liver, and thereby the number of tumors in the liver. Bile acids are formed in the liver and help break down fats during digestion....
1f). Additionally, cells were stained with propidium iodide (PI) and imaged to evaluate the number of dead cells. LSCM imaging indicates that the bacteria were able to grow inside the membrane vesicles, demonstrating negligible effects on bacterial viability following coating with cell membranes (...
Metabolomic experiments usually contain many different steps, each of which can strongly influence the obtained results. In this work, metabolic analyses of six bacterial strains were performed in light of three different bacterial cell disintegration me
is inhibited by pH values below 3.0–2.9.O. oenigrows optimally within a pH range of 4.5–5.5. Thus, a major benefit of malolactic fermentation, for the bacterium, is surprisingly acid reduction. By metabolizing malic to lactic acid, the number of carboxyl groups is halved, acidity is reduc...
