Bacteriohopanepolyols in tropical soils and sediments from the Congo River catchment area
The Congo River basin drains the second largest area of tropical rainforest in the world, including a large proportion of pristine wetlands. We present the first investigation of the full bacteriohopanepolyol (BHP) inventory from a suite of tropical soils and, by comparison with other published data...
