Substances that maintain a highly hypertonic environment, like sugar and salt, are used in the production of dried meat, fruits or fish (for example, cod) because the material to be conserved is then dehydrated and the resulting dryness prevents the growth of populations of decomposer beings (since these beings also lose water and die).arrow_forward

After some testing, you have found that the substrate degradation rate follows the following relationship instead: -rut = k0.5XaS0.5 where -rut = substrate utilization rate (mg/L•day) k = 4 (L/mg•d2) S = substrate concentration (mg/L) Xa = active microbial concentration (mg/L) You have also determined coefficients of bacterial growth on this substrate under aerobic conditions to be Y = 0.25 g VSSa/g substrate and b = 0.08/d. (VSSa, active volatile suspended solids) Estimate the effluent substrate concentration when treating the above wastewater in a CSTR (continuously stirred tank reactor) with recycle while operating at a θx (MCRT, mean cell residence time) of 4 day.arrow_forward

Explain, in your answer, the effect of changing the zone tension on the homeostasis capacity of the bacteria you use and their ability to withstand the osmotic pressure of the new surrounding solvent. In your answer, state how osmosis works and state the degree of tension of the solution (isotonic, hypertonic or hypotonic).
