The article presents a research on use of structured silicon for revealing transient and integrated signal transductions in microbial systems. Topics discussed include bacterial response to transient physical stress is critical to their homeostasis and survival in the dynamic natural environment; and lack of biophysical tools capable of delivering precise and localized physical perturbations to a bacterial community.

During a previous study on the molecular interaction between commensal bacteria and host gut immunity, two novel bacterial strains, A911[supT] and G707 [supT], were isolated from the gut of Drosophila melanogaster. In this study, these strains were characterized in a polyphasic taxonomic study using phenotypic, genetic, and chemotaxonomic analyses. We show that the strains represent novel species in the family Acetobacteraceae. Strain G707[supT], a highly pathogenic organism, represents a new species in the genus Gluconobacter, "Gluconobacter morbifer" sp. nov. (type strain G707 = KCTC 22116[supT] = JCM 15512[supT]). Strain A911[supT], dominantly present in the normal Drosphila gut community, represents a novel genus arid species, designated "Commensalibacter intestini" gen. nov., sp. nov. (type strain A911 = KCTC 22117[supT] = JCM 15511[supT]) [ABSTRACT FROM AUTHOR]
