The effect of sugar concentration on yeast growth associated with floral nectar and honey

Background: Floral nectar and honey vary in sugar concentration, from low concentration to high honey. Variation is a gradient that determines yeast growth can lead its ecological niche specialization. Objective: Evaluate the effect of on kinetics cell size yeasts isolated floral Melipona beecheii. Methods: Four strains identified as Metschnikowia koreensis Sympodiomycopsis paphiopedili, nectar, Starmerella apicola 2, beecheii were grown artificial media with 10, 20, 40 60% glucose. We evaluated culture density (cells / µL), parameters, each strain. Results Conclusions: Strains had rates at highest glucose concentrations, while grew best concentrations. Cell decreased increased all strains. The data supports hypothesis an filter modifies morphology associated flowers leads specialization colonize plant-bee environments.
