Introduction pH affects the structure and function of physiochemical properties Study hypothesis that altering pH affects the structure, function, and process in biological processes Biological processes depend on the environment pH affects the speed and complexity of biological processes Fermentation processes increase with increase in acidity
Rationale pH determines the function and structure of biological molecules (Sanchez-Clemente et al., 2018) Ph affects chemical reactions thermodynamic forces, especially those involving metabolic protons (Sanchez-Clemente et al., 2018) Bacteria growth conditions primarily influence biological processes (Kurniawan et al., 2018) pH changes in solutions result in alterations in bacterial dispersion and consequent physiochemical properties (Alpaslan, et al., 2017)
Background Research identifies pH as a significant factor affecting the acidity of products in biological processes (Yang et al., 2018) Different physiochemical properties affect Ph-sensitivity (Yang et al., 2018) Extreme pH changes are associated with extinction of bacterial population in an environment of chemical process (Ratzke and Gore, 2018) pH has significant influence in the growth of organisms It also influences genetic expression, with low pH being ideal for optimal expression (Huang et al., 2017)
