Adaptations in growth factor requirements for lactic acid bacteria.
Adaptive processes in bacteria, whereby growth of organisms in deficient or drug-enriched media can be initiated through the production of new or latent enzyme systems, have been widely described. Reviews on this subject by Karstrom (1938), Dubos (1940), and Monod (1947) have provided examples of adaptation in bacterial carbohydrases and proteases, in enzymes of fermentation and glycolysis, and...
متن کاملLactic acid bacteria as probiotics.
A number of Lactobacillus species, Bifidobacterium sp, Saccharomyces boulardii, and some other microbes have been proposed as and are used as probiotic strains, i.e. live microorganisms as food supplement in order to benefit health. The health claims range from rather vague as regulation of bowel activity and increasing of well-being to more specific, such as exerting antagonistic effect on the...
متن کاملLactic acid bacteria as probiotics*
Lactic acid bacteria (LAB) are commonly found on human and animal mucous membranes in dairy products and naturally on some plant surfaces. They are normal residents of the gastrointestinal tract of human beings. Several species are commercially used in production of fermented milks, yoghurt, other dairy and meat products, as well as other foods. The antimicrobial activities of LAB have been kno...
متن کاملLactic acid bacteria as live vaccines.
Mucosal routes for vaccine delivery offer several advantages over systemic inoculation from both immunological and practical points of view. The development of efficient mucosal vaccines therefore represents a top prority in modern vaccinology. One way to deliver protective antigens at the mucosal surfaces is to use live bacterial vectors. Until recently most of these were derived from attenuat...
متن کاملGlutamine and Glutamic Acid as Growth Factors for Lactic Acid Bacteria
In 1939 McIlwain, Fildes, Gladstone, and Knight found that the growth of Streptococcus hemolyticus depended upon the addition of glutamine to their medium, the presence of as little as 0.1 y per ml. producing noticeable growth in 24 hours (1). dl-Glutamic acid also exhibited a growth action, but over 10,000 times as much was required for a similar effect. The suggestion was made that the organi...
