ABSTRACT
Microbial fermentations are currently used for the production of a diverse array of biomolecules including amino acids, fine chemicals, solvents, enzymes, hormones, and antibiotics. Such diversity may be attributed to many factors, including the high surface-to-volume ratio and the ability to utilize a wide spectrum of carbon and nitrogen sources. Prokaryotic organisms differ from yeast and fungi as well as other eukaryotes in a number of ways. Accelerostat is a special type of chemostat in which the transition from growth rate to another is made smoothly through the use of a special computer program. Microorganisms are capable of detecting extracellular and intracellular metabolites by virtue of their ability to sense and transmit signals to sensory control mechanisms, for example, two-component transduction mechanisms and transcription factors. The logarithm of a number is the exponent to which people must raise a base to obtain that number.
