متن کاملOn-line estimation of microbial specific growth rates
-Continuous time algorithms for the on-line estimation of microbial specific growth rates of fermentation processes are proposed. An important feature of the proposed algorithm is that they do not require any kind of analytical description of the specific growth rate which is simply considered as an unknown bounded time varying parameter. Four different input-output configurations are considere...
متن کاملNature, nurture and growth
FOR the first time in history, almost all of the world’s people are bound together in a global capitalist system. This momentous development forces us to think anew about the world economy. In the past, differences in policies across regions of the world resulted in vast differences in economic performance; in the future, policies are likely to be more similar. As a result, large parts of the d...
متن کاملControlling Microbial Growth
In its strictest sense, sterilization refers to the removal or destruction of all microbes, including viruses and bacterial endospores, in or on an object. (The term does not apply to prions.) In practical terms, sterilization techniques eradicate harmful microbes, but some innocuous microbes may still be pres ent. The term aseptic describes an environment or procedure that is free of con tam...
متن کاملMicrobial uptake of radiolabeled substrates: estimates of growth rates from time course measurements.
The uptake of [3H]glucose and a mixture of 3H-labeled amino acids was measured, in time course fashion, in planktonic microbial assemblages of the eastern tropical Pacific Ocean. The average generation times of those portions of the assemblages able to utilize these substrates were estimated from a simple exponential growth model. Other workers have independently used this model in its integrat...
