Prospects of fluorescence methods application for monitoring of cyanobacterial cultures in biotechnology

Abstract

Cyanobacteria are photosynthetic microorganisms that possess a high potential for innovative applications in agriculture, food production, cosmeticals, wastewater remediation, biofuels, antioxidative enzymes production, etc. During the industrial cultivation of cyanobacteria several parameters as growth rate, physiological state and algological purity of the culture should be controled permanently. One of the methods that can provide on-line monitoring of cyanobacterial cultures and further process automatization is a fluorescence spectroscopy. In this work several fluorescence techniques are analysed and their possible adaptation for biotechnological applications is suggested.
