“…Lactic acid bacteria (LAB) are an example of organisms that evolve depending on the environment in which they live (Douglas et al 2015 ). Lactic acid bacteria are generally auxotrophic for some compounds; they are quite demanding nutritionally and limited in their environmental tolerances (Christiansen et al 2008 ; Gomaa and Rushdy 2014 ).…”

In the present study, a Lactobacillus plantarum FPL strain exhibiting fructophilic behavior has been isolated for the first time from honeydew. It is a probably syntrophic bacterium inhabiting the gastrointestinal tract of Coccus hesperidum L. and taking part in sugar metabolism. The promising growth characteristics and biochemical properties of Lb. plantarum FPL indicate that this may be a facultatively fructophilic species, whose properties are not associated with the loss of the alcohol/acetaldehyde dehydrogenase gene. The article attempts to classify the peculiar behavior of this strain by means of tests that are characteristic for FLAB as well as through a classic identification approach. In this study, we used a reference strain Lb. plantarum NRRL B-4496, which showed no fructophilic properties. With the FLAB group, the new strain shares the habit, such as a fructose-rich environment, the preference of this sugar for growth, and similar growth curves. However, it exceeds FLAB in terms of osmotolerance to high sugar content. The fructophilic Lb. plantarum FPL strain can proliferate and grow on a medium wherein the sugar concentration is 45 and 50% (w/v). Our findings indicate that honeydew can be a promising source of new fructophilic lactic acid bacteria.Electronic supplementary materialThe online version of this article (10.1007/s13213-018-1350-2) contains supplementary material, which is available to authorized users.

Bee honey have a highly intensity and specialized microbiota which plays an important role in metabolism, immunity, growth as well as development an antagonistic effect against pathogens. Thus, the aim of work was isolation genotype characterization of some strains of lactic acid bacteria (LAB) from fresh clover bee honey. Five samples of fresh clover honey were analyzed to detect the microbiome contents. Dilution method and cultivation in selective media was used for counting of LAB strains, and the isolates were identified by their morphological characteristics that measured using Gram staining method and screened by catalase activity. Furthermore, the morphological characteristics of bacterial cells were examined using Scanning Electron Microscope (SEM). The genotype of isolated strains was carried out by Polymerase Chain Reaction (PCR) method. The results showed that, two novel bacterial strains of LAB were isolated from fresh clover bee honey. The strains of LAB which identified were; Lactobacillus brevis MK250013 and Lactobacillus casei MK250003.
