The look for new manufacturers of biologically lively ingredients (BAS) opposed to human and animal illnesses remains to be a big activity in biology and medication. Experimental paintings has to be conducted good just before want since it takes a normal of ten years to increase a brand new drugs, in addition to overtime to place it out there. examine of the Protozoa types a unique department of biology - protozoology. the normal fields of protozoology are taxonomy, phylogeny, morphology, cytology, evolution, ecology and host parasite-interactions. The Protozoa is the one taxon one of the microscopic organisms, which has no longer been repeatedly studied as a resource of BAS. This e-book then is the results of the learn at the undertaking: "Biologically lively ingredients of the Mastigophora (Flagellates)". The study was once performed on the Laboratory of Antibiotics, division of Microbiology, organic school of Moscow nation college. Articles of alternative authors at the topic were regarded as the $64000 a part of this reference booklet. The aim of the reference booklet is to explain medical techniques, which result in acquiring biologically energetic components from cultures of protozoa; the e-book studies the ancient heritage in reference to modern improvement of the sector. N.N. Sukhareva ACKNOWLEDGMENTS The study was once played in fruitful cooperation with my study affiliates (V. Urinyuk, T. Titiova, L. Udalova, R. Zeleneva, V. Brusovanik, M. Zaretskaya), postgraduate scholars (N. Kalenik, M. Chuenkova, V. Vasilevskaya, V. Khorokhorina), my colleagues at Moscow nation college (Yu. Kozlov and I.

Brucei has a molecular weight of 28 kDa . This enzyme hydrolyzes Iysophospholipids to yield glycerophosphate choline and free fatty acids. The latter can cause haemolysis, which is the result of free fatty acid release. Nowadays, the trypanosomes cultivated in media display autolysis during the aging phase (Mellors and Samad, 1989). The release of phospholipase Al is very significant during the same phase of growth. The specific ity of this phospholipase consists of its ability to hydrolyze PC long chain fatty acids when it is mixed with a detergent such as Triton X-I0 (Mellors and Samad, 1989).

Little is known about the mechanism of cell volume regulation under hyperor hypotonic conditions . The importance of inorganic nutrition for protozoa was emphasized by S. Hutner (1972a). The composition of inorganic salts determines the osmotic strength of a medium (Vieira, 1998). The role of Ca2+ is of great importance, as its concentration controls cell shape in Euglenids and can cause differentiation in trypanosomes cultured in vitro (Murray, 1981; Sukhareva 1968, 1989). 3 Influence oftemperature Temperature is a critical factor for the growth of protozo a and biosynthesis of BAS (Sukhanova, 1968; Poljansky, 1973).
