Explain the importance of bacterial dormancy. Define signal transduction, and why it is so important? In a typical PCR reaction, what phenomena are occurring at temperature ranges (a) 90-95 C , (b) 50-70 C , and (c) 70-75 C?
2 and 3). Bacterial biomass production did not show such biogeographic patterns (Supplementary Table S1 and Supplementary Fig. 3), presumably because it reflects the heterotrophic bulk activity of the entire prokaryotic communities which is more related to local substrate availabilities and spatio-...
Discuss the morphological features of a bacterium, that can be seen under the microscope, in a Gram stained (a) Define E. coli. (b) Explain its role in genetic engineering. What is one advantage of using E. coli to study bacterial gr...
However, with cold storage and an inoculum of 10 1 cfu ml -1 (low bacterial concentration) and a pre-incubation temperature of 30°C a significant shift in the growth curve was observed over that pre-incubated at 14°C, with the appearance of a lag of about 7.7 d. At a pre-...

On the other hand, bacterial βGLU, which is expressed in human gut microbiota and most strains of Escherichia coli shows 45% sequence similarity with human βGLU. Also, it has a bacterial loop containing 17-amino acid residues not found in human βGLU, an optimal activity at neutral pH an...
Role of transparent exopolymer particles (TEP) in initial bacterial deposition and biofilm formation on reverse osmosis (RO) membrane S.C. Leterme, C. Le Lan, D.A. Hemraj, A.V. Ellis The impact of diatoms on the biofouling of seawater reverse osmosis membranes in a model cross-flow system...
Thus far, many endogenous and exogenous sources of cirDNA in humans have been identified, e.g., apoptosis, necrosis, bacterial, and viral DNA [6]. Although apoptosis and necrosis are considered to be the main processes for producing cirDNA, numerous studies have demonstrated that cirDNA can ...
of monocyte chemoattractant protein-1 (MPC-1) and transforming growth factor-β1 (TGF-β1) in polymyositis/dermatomyositis (PM/DM) patients complicated with interstitial lung disease (ILD), to reveal the significance of the changes in these levels in the pathogenesis of PM/DM complicated with ...
