[Biosynthesis of group B vitamins by yeasts--symbionts of xylophagous insects]. 1975

L A Gusteleva

The biosynthesis of vitamins of the B group was studied in the yeasts Debaryomyces and Zygowillia--the symbionts of insects--xylophages. These yeasts provide the vitamins of the B group (biotin, thiamine, inositol, pyridoxine, nicotinic and pantothenic acids) for the preimaginal phases of insects--xylophages. The presence of these vitamins under the bark of trees and in other places of insect habitation is related to the viability of the yeasts. The content of the vitamins in the phloem depends on the quantity of the yeast organisms in it.

UI	MeSH Term	Description	Entries
D007294	Inositol	An isomer of glucose that has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379) Inositol phospholipids are important in signal transduction.	Myoinositol,Chiro-Inositol,Mesoinositol,Chiro Inositol
D009539	Nicotinic Acids	2-, 3-, or 4-Pyridinecarboxylic acids. Pyridine derivatives substituted with a carboxy group at the 2-, 3-, or 4-position. The 3-carboxy derivative (NIACIN) is active as a vitamin.	Acids, Nicotinic
D010205	Pantothenic Acid	A butyryl-beta-alanine that can also be viewed as pantoic acid complexed with BETA ALANINE. It is incorporated into COENZYME A and protects cells against peroxidative damage by increasing the level of GLUTATHIONE.	Vitamin B 5,Calcium Pantothenate,Dexol,Vitamin B5,Zinc Pantothenate,B 5, Vitamin,B5, Vitamin,Pantothenate, Calcium,Pantothenate, Zinc
D011549	Pseudomonas	A genus of gram-negative, aerobic, rod-shaped bacteria widely distributed in nature. Some species are pathogenic for humans, animals, and plants.	Chryseomonas,Pseudomona,Flavimonas
D011736	Pyridoxine	The 4-methanol form of VITAMIN B 6 which is converted to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, aminolevulinic acid. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990).	Pyridoxin,Pyridoxine Hydrochloride,Pyridoxol,Pyridoxol Hydrochloride,Rodex
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.	Animal,Metazoa,Animalia
D001409	Bacillus cereus	A species of rod-shaped bacteria that is a common soil saprophyte. Its spores are widespread and multiplication has been observed chiefly in foods. Contamination may lead to food poisoning.
D001517	Coleoptera	Order of winged insects also known as beetles comprising over 350,000 species in 150 families. They possess hard bodies with mouthparts adapted for chewing.	Beetles,Beetle
D001710	Biotin	A water-soluble, enzyme co-factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk.	Vitamin H,Biodermatin,Biokur,Biotin Gelfert,Biotin Hermes,Biotin-Ratiopharm,Biotine Roche,Deacura,Gabunat,Medebiotin,Medobiotin,Rombellin,Biotin Ratiopharm,Gelfert, Biotin,Hermes, Biotin,Roche, Biotine
D013559	Symbiosis	The relationship between two different species of organisms that are interdependent; each gains benefits from the other or a relationship between different species where both of the organisms in question benefit from the presence of the other.	Endosymbiosis,Commensalism,Mutualism
