Diversity of Formyltetrahydrofolate Synthetases in the Guts of the Wood-Feeding Cockroach Cryptocercus punctulatus and the Omnivorous Cockroach Periplaneta americana

摘要

We examined the diversity of a marker gene for homoacetogens in two cockroach gut microbial communities. Formyltetrahydrofolate synthetase (FTHFS or fhs) libraries prepared from a wood-feeding cockroach, Cryptocercus punctulatus , were dominated by sequences that affiliated with termite gut treponemes. No spirochete-like sequences were recovered from the omnivorous roach Periplaneta americana , which was dominated by Firmicutes -like sequences.
