In the same period, the French pediatrician Henry Tissier discovered the predominance of bifidobacteria in the feces of Development of Probiotics and Prebiotics 23 healthy infants, and postulated their effectiveness in preventing infections (Said and Mohamed, 2006). Experimental work on the effect of ingestion of “beneficial microorganisms” on human health was carried out in the 1930s, but the results were not clearly positive, and this line of research was abandoned for 40 years. The term probiotic, from Greek “for life,” was used for the first time by Lilly and Stillwell (1965) to define substances produced by microorganisms which would enlarge the growth phase of other microorganisms.

Centrifugation is more appropriate for unicellular microorganisms, such as yeasts or bacteria, but in these cases, flocculation is often used as a complementary operation because of the small size of the individual cells. Filtration is more appropriate for multicellular organisms with a filamentous morphology. Bearing in mind the additional difficulties posed by intracellular enzymes, one of the top priorities when genetically modifying an organism for enzyme production is to favor modifications that allow the extracellular secretion of the enzyme (Illanes 2008).
