REU: Structure of and Metabolic Interactions within the Microbial Community of Gryllids

Drs。Michael Klug和Michael Kaufman提出了一项蟋蟀后肠内相互作用的结构和代谢研究。大多数微生物群落的结构和种群动态尚不清楚。由于对天然微生物系统研究的限制，本研究提出了对蟋蟀（直翅目：灰蟋蟀科，灰蟋蟀科）后肠局部细菌群落的研究，以解决这些基本问题。检查蟋蟀后肠系统的主要优点包括有机会将无菌昆虫与特定细菌种群重新联系起来，以便测试发酵群落内的假设和相互作用。这些研究将阐明演替模式、代谢特征和调节发酵细菌群落内种群的因素。此外，他们将解决有关细菌种群之间以及微生物与昆虫之间关系的基本问题。

Drs. Michael Klug and Michael Kaufman propose a structural and metabolic study of interactions within the hindgut of crickets. The structure of and population dynamics within most microbial communities are not well understood. Constraints imposed in the study of natural microbial systems lead to this proposal to study localized bacterial communities in the hindgut of crickets (Orthoptera: Gryllidae, Gryllotalpidae) in order to address these fundamental questions. The principle advantages of examining the cricket hindgut system include the opportunity to re-associate germ-free insects with specific populations of bacteria in order to test postulates and about interactions within fermentative communities. These investigations will elucidate successional patterns, metabolic characteristics, and factors regulating populations within the fermentative bacterial community. Furthermore, they will address basic questions concerning the relationship between populations of bacteria and between microorganisms and insects.
