摘要：

Cyanobacterial hepatotoxins and anatoxin-a, a neurotoxin, were shown to be degraded when crude extracts of lysed toxic laboratory strains of cyanobacteria were exposed to natural populations of micro-organisms from lakes. While anatoxin-a decayed equally fast with all the inocula from lake sediment and water, the degradation rate of hepatotoxins was higher with inocula from places at which cyanobacterial water blooms had occurred than with inocula from places with no known mass occurrences of cyanobacteria. Degradation was slowest when an inoculum from a humic lake was used. A part of the loss of the toxins was shown to be due to adsorption on lake sediments.
