The effect of humic substances isolated from a variety of marine and lacustrine environments on different microorganisms

Oceanologia, 2001
The antimicrobial activity of twelve preparations of humic substances isolated from sea water, marine bottom sediments and lake water was examined. Humic substances from marine bottom sediment samples were fractionated into humic and/or fulvic acids ...
