title: Production of B-group vitamins by bacteria isolated from soil, rhizosphere, and mycorrhizosphere of pine (Pinus sylvestris L.).
abstract: Studies on the production of B vitamins by soil, rhizosphere, and mycorrhizosphere bacteria have revealed that such ability is common among these organisms. Thiamin, nicotinic and folic acids were produced by the greatest number of bacteria. Bacteria isolated from the rhizosphere and mycorrhizosphere produced more riboflavin than those originating from the soil distant from roots. In general the soil strains produced higher amounts of vitamins (except riboflavin) than the root-zone isolates. Two and three vitamins were produced by the majority of bacteria. The synthesis of four and five vitamins was found in few strains only.
