In plants and in many microorganisms (but not in E. coli), 3,4-dihydroxy-2-butanone-4-phosphate synthase and GTP cyclohydrolase II are expressed as a fusion protein with GTP cyclohydrolase II as the C-terminal domain. The ratio of product formation of the two initial reactions of the convergent biosynthetic pathway is thus rigidly coupled. 

Macroscopic Thermodynamics and the Description of Growth and Product Formation in Microorganisms... 

Equation (12) will be shown to allow the formulation of an efficiency measure, which can be used to analyse growth and product formation in microorganisms, its development will be undertaken in the next section. 

The rate of product formation, rfi, depends upon the state of the cell population, environmental condition, temperature, pH, media composition and morphology with cell age distribution of the microorganism.2 3 A similar balance can be formulated for microbial biomass and cell concentration. The exponential phase of the microbial growth in a batch culture is defined by ... 

Microbial cells transported with the stream of fluid above the surface interact with conditioning films. Immediately after attachment, microorganisms initiate production of slimy adhesive substances, predominantly exopolysaccharides (EPS) that assist the formation of microcolonies and microbial films. EPS create bridges for microbial cells to the substratum and permit negatively charged bacteria to adhere to both negatively and positively charged surfaces. EPS may also control interfacial chemistry at the mineral/biofilm interface.
