Literature on microbial physiology and biochemistry may be helpful for the choice of strains to find enzymes for the biotransformation of naturally occurring substances. Screening of enzymes to convert unnatural compounds however usually implies an accidental selection of microorganisms. Actually, even such a preliminary approach gives valuable informations about the occurrance of an enzyme activity.

The continuous culture system, or chemostat, is an ideal laboratory system for studying microbial physiology and has been instrumental in helping to solve many problems, not just in lipid biochemistry. Whether continuous culture would be used on a commercial scale is uncertain as there are high costs involved in ensuring complete freedom from adventitious contamination with other microorganisms. However, such... 

The question what is the natural role of microbial surfactants would appear to be of fundamental significance in microbial physiology and of practical value in designing selection methods for improved molecules. However, the question has a basic flaw. There is no reason to suspect that surfactants have one natural role. As described in this chapter, microbial surfactants have very different structures, are produced by a wide variety of microorganisms, and have very different surface properties. Thus, it will be necessary to analyze each surfactant, or group of surfactants, separately. Only then may it be possible to draw any generalizations. 

The goal is to achieve a polyphasic taxonomic approach for authentication and quality control of microbial strains. Each morphological, physiological, cytochemical, and molecular method has hmitations. Combining and comparing the results enable us to obtain a more accurate and complete picture of the microorganism s identity. 

Flocculation of microorganisms is thought to be affected by a bridging mechanism of polymers excreeted by the microorganisms or exposed to the microbial surface under suitable physiological conditions. More recently new work on adhesion of bacteria have been carried out (Van Loosdrecht et al., 1990) see Chapter 7.9.
