Abstract

Bulk DNAs were extracted from 79 deep-sea sediment core samples of the Nankai Trough, off-central Japan. Total 429 clones of the genes encoding ammonia monooxygenase, amoA (β), and particulate methane monooxygenase, pmoA, yielded ten and two operational amoA (β) and pmoA units (OAUs and OPUs), respectively. Patchy distributions of OAUs and OPUs were not correlated to and explained by geological and geochemical features of the sediments.
