Novel gut bacterial fauna of Gryllotalpa africana Beau. (Orthoptera : Gryllotalpidae)

摘要

Gryllotalpa africana (Beauvois) is a successful group of detritus feeder therefore it is an important both for their roles in carbon cycling in the environment and converting organic decaying material in to biofuel. Hence, bacterial diversity and relationship were explored from the mole cricket G.africana (Beau) to show ideal symbiotic association. The analysis and characterization of gut micro biota of G.africana (Beau) revealed the presence of 10 species and two genera of bacteria viz. Acidiphilium rubrum, Dienococcus proteolyticus, Sporosarcina ureae, Micrococcus varians, Micrococcus kristinae, Acetobactrium, Alcaligenes eutrophus, Micrococcus roseus, Micrococcus lylae, Sporosarcina, Citrobacter amalonaticus and Corynebacterium xerosis. All the species and genera were confirmed by observing their morphological features of the colony and various biochemical tests. These results indicate that the presence of mole cricket specific bacterial lineages implies relationship of gut microbes and their host mole cricket. The outcome of this work indicted that the gut bacterial fauna of G.africana shows the species-rich with greater diverse communities which might be providing resistance to invasion of pathogenic bacteria.
