Abstract:

Methane evolution from succulent marsh plants such as Salicornia is apparently less than from marsh plants of lower cell-fluid content, under similar microbial conditions. Cellulose, a principal source of methane in marshes, is quickly degraded bacterially, but methane evolution continues at high levels from the humic marsh organic matter. In addition to other polymers, intermediate degradation products, such as alcohols and organic acids, may play an important role in continuing methane evolution, and in aerosols of coastal regions.
