“…and plays a role in carbohydrate metabolism. Genomic analysis has identified various genes in the G. apicola strain, which involve sugar absorption and fermentation (Alatawy et al 2020). G. apicola strain contains many sugar transporters and sugar utilization pathways (Moran 2015).…”

Abstract. Niode NJ, Adji A, Rimbing J, Tulung M, Tallei TE. 2021. Composition and diversity of bacteria from giant Asian honeybee Apis dorsata gut. Biodiversitas 22: 906-912. As a social insect, honeybee possesses a unique gut bacteria community. Therefore, we need to understand the composition and diversity of bacteria in Apis dorsata gut, the largest honeybee species that live in the forest, especially in Southeast Asia. The present study aimed to investigate the gut bacteria of A. dorsata using a metabarcoding approach. The DNA barcode region used in this approach was the V3-V4 region of 16S rRNA. Honeybees were caught in a forest area located in Tareran, South Minahasa, North Sulawesi, Indonesia. There were 11 phyla identified from the gut of A. dorsata. The most abundant phyla were Firmicutes (95.8%), Proteobacteria (3.7%), and Actinobacteria (0.4%). The class Bacilli was responsible for 94.5% of the total bacterial population, the dominant family was Bacillaceae (87.2%), and the dominant genus was Bacillus (87%). Simpson (1-D) 0.24 and Shannon diversity index 0.98 indicated that the diversity of the genera was low. A nonsignificant number of species belong to the lactic acid bacteria was also detected, which may have certain benefits that need to be investigated further.

“…Microbial communities associated with nutrition provisioning, mainly present in the ileum, and bee health presumably co-evolved with food transfer, storage, digestion, and processes in the enzymatically active and nutrient-rich midgut [ 23 , 45 ]. In addition to the function of the ileum in water and nutrient absorption [ 46 ], the presence of symbionts, particularly Snodgrassella alvi and Gilliamella apicola , is involved in the biofilm formation, which presumably provides a protective layer against parasites [ 47 ]. Some bacterial communities are present in the rectum, generally provided with unused nutrients during winter [ 45 ].…”

We investigated the bacterial community of bee bread and bee pollen samples using an approach through 16 s rRNA high-throughput sequencing. The results revealed a higher bacterial diversity in bee bread than in bee pollen as depicted in taxonomic profiling, as well as diversity indices such as the Shannon diversity index (3.7 to 4.8 for bee bread and 1.1 to 1.7 for bee pollen samples) and Simpson’s index (>0.9 for bee bread and 0.4–0.5 for bee pollen). Principal component analysis showed a distinct difference in bacterial communities. The higher bacterial diversity in the bee bread than bee pollen could presumably be due to factors such as storage period, processing of food, fermentation, and high sugar environment. However, no effect of the feed (rapeseed or oak pollen patties or even natural inflow) was indicated on the bacterial composition of bee bread, presumably because of the lack of restriction of foraged pollen inflow in the hive. The diverse bacterial profile of the bee bread could contribute to the nutritional provisioning as well as enhance the detoxification process; however, a thorough investigation of the functional role of individual bacteria genera remains a task for future studies.
