Acetobacter tropicalis increases development rate compared to Lactobacillus brevis treatment

  Addition of the AAB species  Acetobacter tropicalis  to the food resource ( At  treatment), 2) addition of the LAB species  Lactobacillus brevis  to the food resource ( Lb  treatment), and 3) no microbial inoculation ( No-Ad  treatment).  At  and  Lb  strains were selected as representative AAB and LAB based on their different influences on  D. melanogaster  life history traits, with  At- inoculated flies displaying faster development times and shorter periods of starvation resistance than Lb-inoculated flies https://www.pnas.org/doi/10.1073/pnas.1907787116#sec-1

Removal of the gut bacteria represses oogenesis, expedites maternal-to-zygotic-transition in the offspring

- Removal of gut bacteria (specially Acetobacter) inhibits oogenesis, accelerates maternal-to-zygotic transition in offspring, and reveals hidden phenotypic variations in mutants. - The Drosophila Aldh gene appears to mediate repressed oogenesis in flies lacking Acetobacter. https://www.nature.com/articles/ncomms11280
