This paper deals with the design of a feedback controller for fed-batch microbial growth processes which forces the substrate concentration Csto a desired setpoint c∗s, starting from an arbitrary (initial) substrate concentration and when non-monotonic growth kinetics apply.
Inhibitors can be broadly categorized into those compounds the plant produces itself to restrict microbial growth and process-derived compounds (Boussaid et al. 2001, Liu 2010).
Nitrogen supplementation of the raw substrate in SSF may stimulate microbial growth or improve process efficiency and can play an important role not only as nutritive compounds but also can influence pH changes during the process (Correia et al. 2007).
Vaccine manufacturers have used preservatives to prevent microbial growth during the manufacturing process or when packaged as "multi-dose" products to allow for multiple punctures of the same vial to dispense multiple vaccinations with less fear of contamination.
The model included the following: microbiological processes —exogenous and endogenous nitrate respiration coupled to microbial growth and decay; geochemical processes —precipitation or dissolution of calcite; and isotopic fractionation —δ15N-NO3−, δ18O-NO3−, and δ13C-DIC, incorporating the full δ13C isotope geochemistry involved in EIB.
Biofouling process or biofilm formation is a multistage process that is complex, slow, reversible or irreversible process where microbial growth can take couple of weeks or months.
An effective application of glycerol, for example, as low-cost substrate for microbial growth in industrial fermentation processes to specific products will reduce the production costs for biodiesel.
These processes influence microbial growth and population dynamics, in combination with other ecological processes, such as predation [2].
According to Fialho et al. (2010), microbial growth and efficiency of composting process also depends on the type of substrate.
SSF refers to the process whereby microbial growth and product fermentation occur on the surface of solid materials.
