Opis

Advances in Microbial Ecology was established by the International Commis sion on Microbial Ecology to provide a vehicle for in-depth, critical, and, it is hoped, provocative reviews on aspects of both applied and basic microbial ecol ogy. In the five years of its existence, Advances has achieved recognition as a major source of information and inspiration both for practicing and f"
