Synthesis of B vitamin complex by intestinal bacteria of carp fed artificial food

Synthesis of B vitamin complex by intestinal bacteria of carp fed artificial food. Trepsiene, O.; Jankevicius, K.; Lubianskiene, V. (Inst. Zool. Parasitol., Vilnius, USSR). Liet. TSR Mokslu Akad. Darb., Ser. C, (3), 71-8 (Russian) 1977. CODEN: LMDCAO. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) Intestinal microorganisms of the carp (Cyprinus carpio) fed on artificial food could produce vitamins: biotin [58-85-5], thiamin [59-43-8], pyridoxine [65-23-6], nicotinic acid [59-67-6]. The highest amts. of these vitamins in the biomass of bacteria were: 4.76, 18.08, 17.39, and 113.55 mg/g biomass, resp.. The intestinal bacteria strains in carp did not produce meso-inositol and they showed a lesser prodn. of pantothenic acid [79-83-4] (only 18% of the investigated bacteria strains synthesized this vitamin). The intestinal bacteria strains of yearling carp (35.0 mg investigated vitamins/g biomass) were more active than those of the 2nd and the 3rd year carp (resp. 33.0, 19.1 mg/g). B vitamins were synthesized most actively by Pseudomonas fluorescens, P. denitrificans, and P. scissa.

Body resistance to sonic effects against the background of an unbalanced nutritional pattern

Body resistance to sonic effects against the background of an unbalanced nutritional pattern. Pokrovskii, A. A.; Korovnikov, K. A. (Inst. Pitan., Moscow, USSR). Vopr. Pitan., (5), 67-72 (Russian) 1977. CODEN: VPITAR. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) A 14-day excess of thiamin [59-43-8], riboflavin [83-88-5], pyridoxine [65-23-6], ascorbic acid [50-81-7], or vitamin B12 [68-19-9] in Wistar rats on a casein 24, starch 62, lard 5, sunflower oil 5, salts 4% ration allowed less audiogenic convulsions than a deficiency of all vitamins. Pyridoxine (4-fold excess) exerted the greatest protective effect; this effect was enhanced by addn. of excess riboflavin, esp. when accompanied by excess succinate [110-15-6] (10 mmol/kg i.p.) and (or) glutamic acid [56-86-0] (0.25% of feed). Plasma 11-hydroxycorticosteroid concn. in rats given excess pyridoxine, riboflavin, succinate, and glutamate was 43.8 mg% as compared with 25.3 mg% in controls. The results are discussed in relation to the Roberts cycle and central nervous system stimulation and inhibition.
