Spectroscopic Methods of Estimation of Blue-Green Algae Physiological State After Weak External Actions
Today cyanobacterial blooms in open reservoirs and estuaries become the most important ecological problem. One of the ways to solve this problem is to develop innovative methods of control of the number of bloom-forming cyanobacteria based on weak external actions, which have no serious consequences for the whole ecological system. A novel effective technique of in vivo estimation of cyanobacterial viability for on-line ecological monitoring of the results of weak external actions was elaborated by us using a combination of different spectroscopic methods. It was shown that the results obtained by means of conventional spectrophotometry and fluorimetry for cyanobacterial culture as a whole and the data obtained by fluorescent spectral microscopy applied to a single cell are strictly related.
