|The aim of the study was to investigate the biotechnical production of the cyanotoxin cyanobacterin by the cyanobacterium Scytonema hofmanni (UTEX 1581) under the influence of the following abiotic parameters: photon flux rate, pH, temperature, different nutrient concentrations nitrate and phosphate as well as of trace elements.
Based on these data, the ecology of Scytonema hofmanni as part of a cyanobacterial community in the Everglades (Florida, USA) was concluded.
A new rapid method was developed to quantify cyanobacterin in the biomass by photometric analysis of DMF-extracts within 24 h.
Cyanobacterin exhibited allelochemical effects and its biosynthesis again is influenced by allelopathy.
Cyanobacterin can be used as a natural herbizide and as a co-antifoulant.
