Abstract
Using spectrophotometry, the effect of viral lysis on light absorption in a virus-infected culture of microalgae Tetraselmis viridis was studied compared with the growth of a control uninfected culture. Some methodological issues of conducting multi-day experiments have been worked out, considering the natural titers of algal viruses, equal volumes of composite microbiota (algal viruses, nutrient medium, and microalgae cultures), conditions (temperature and illumination) in the experiment and control with the prevention of the possibility of viral contamination of microalgae in the control. It was found in the dynamics of experiments that during destruction (lysis) of hosts (microalgae cells) by viruses there was an increase in the amount of dissolved organic matter.

期刊介绍：
Biophysics is a multidisciplinary international peer reviewed journal that covers a wide scope of problems related to the main physical mechanisms of processes taking place at different organization levels in biosystems. It includes structure and dynamics of macromolecules, cells and tissues; the influence of environment; energy transformation and transfer; thermodynamics; biological motility; population dynamics and cell differentiation modeling; biomechanics and tissue rheology; nonlinear phenomena, mathematical and cybernetics modeling of complex systems; and computational biology. The journal publishes short communications devoted and review articles.
