Abstract
This paper describes taxonomic position, phylogeny, and phenotypic properties of 14 lactic acid bacteria (LAB) originating from an Apis mellifera guts. Based on the 16S rDNA and recA gene sequence analyses, 12 lactic acid bacteria were assigned to Lactobacillus kunkeei and two others were classified as Fructobacillus fructosus. Biochemically, all isolated lactic acid bacteria showed typical fructophilic features and under anaerobic conditions grew well on fructose, but poorly on glucose. Fast growth of bacteria on glucose was noted in the presence of oxygen or fructose as external electron acceptors. The residents of honeybee guts were classified as heterofermentative lactic acid bacteria. From glucose, they produced almost equimolar amounts of lactic acid, acetic acid, and trace amounts of ethanol. Furthermore, they inhibited the growth of the major honeybee pathogen, Paenibacillus larvae, meaning that the LAB studied may have the health-conferring properties of probiotics.
