Lignin biodegradation in a variety of natural materials was examined using specifically la-
beled synthetic 14C-lignins. Natural materials included soils, sediments, silage, steer bed-
ding, and rumen contents. Both aerobic and anaerobic incubations were used. No 14C-
labeled lignin biodegradation to labeled gaseous products under anaerobic conditions was
observed. Aerobic 14C-labeled lignin mineralization varied with respect to type of natural
material used, site, soil type and horizon, and temperature. The greatest, observed degra-
dation occurred in a soil from Yellowstone National Park and amounted to over 42% con-
version of total radioactivity to 14CO2 during 78 days of incubation. Amounts of 14C-labe-
led lignin mineralization in Wisconsin soils and sediments were significantly correlated with
organic carbon, organic nitrogen, nitrate nitrogen, exchangeable calcium, and exchange-
able potassium. |
