Abstract

Simple Summary Bees play an essential role in maintaining biodiversity, as they are crucial for the pollination provisions of agricultural crops and for plants in general. In recent years, a decline in bee populations has been noted, especially due to climatic and anthropometric factors and challenges. It is important to develop (or redevelop) approaches that can help preserve these important insects. Improving our knowledge on bees' microbiology can be one of the ways to better understand ecological relations and the life cycle of these beneficial tiny workers. One of the possible alternatives to overcome the decline in bee populations, while improving their health and productivity, is to study their microbiota, and that of their related products, and identify beneficial microorganisms that may be useful for use as probiotics. The microorganisms present in bees' microbiota make an essential contribution to their health by being involved in metabolism and providing food supplies, helping to digest and preserve food, and protecting them from the diseases. In this review, we highlight some of the main bacterial representatives of the microbiota of different species of bees and their by-products, with the focus on microorganisms with characteristics improving health, and other possible applications in the food industry. At the end, "One Health" is not just a book concept, but a real scientific strategy.Abstract Bees are one of the best-known and, at the same time, perhaps the most enigmatic insects on our planet, known for their organization and social structure, being essential for the pollination of agricultural crops and several other plants, playing an essential role in food production and the balance of ecosystems, being associated with the production of high-value-added inputs, and a unique universe in relation to bees' microbiota. In this review, we summarize information regarding on different varieties of bees, with emphasis on their specificity related to microbial variations. Noteworthy are fructophilic bacteria, a lesser-known bacterial group, which use fructose fermentation as their main source of energy, with some strains being closely related to bees' health status. The beneficial properties of fructophilic bacteria may be extendable to humans and other animals as probiotics. In addition, their biotechnological potential may ease the development of new-generation antimicrobials with applications in biopreservation. The concept of "One Health" brings together fundamental and applied research with the aim of clarifying that the connections between the different components of ecosystems must be considered part of a mega-structure, with bees being an iconic example in that the healthy functionality of their microbiota is directly and indirectly related to agricultural production, bee health, quality of bee products, and the functional prosperity for humans and other animals. In fact, good health of bees is clearly related to the stable functionality of ecosystems and indirectly relates to humans' wellbeing, a concept of the "One Health". (AU)
