BIOFERTILIZERS AND COMPOSTING ACCELERATORS OF POLLUTING MACROPHYTES OF A COLOMBIAN LAKE

Composting of the macrophytes Eichhornia crassipes (water hyacinth) and Egeria densa (Brazilian elodea) has been proposed as a final disposal, following their mechanical removal in the lake Fúquene (Ubaté, Cundinamarca). Microorganisms, isolated and selected by antagonism, were evaluated as inoculan...

Microorganisms, isolated and selected by antagonism, were evaluated as inoculants to accelerate the composting and to stimulate plant growth. In microbial biopreparations of bacteria, actinomycetes and fungi, maximum amylolytic activities were found of 2,422 U L-1, 1,744 U L -1and 1,426 U L-1, respectively; cellulolytic activities of 233.2 U L-1, 668 U L-1 and 701.4 U L-1 and proteolytic activities of 660 U mg-1, 520 U mg-1 and 400 U mg-1.
