The influence of the nutrient medium on the morphological features and cell viability of the microalgae Chlorella vulgaris Beijer

This paper discusses morphological features and the nature of viability cell groups microalgae Chlorella vulgaris Beijer., growing in an artificial nutrient medium. It has been found that aspect, have a unicellular structure rounded or ellipsoidal shapes with diameter structures from 2 to 10 microns. The chlorella is represented as thin shell, cytoplasm which nucleus decorated chloroplast immersed. optimal parameters for intensive growth were temperature values range +27+29C. In such values, showed best results terms rate its index. At same time, culture cells, having ability outstrip growth, able maintain systematic variety long time. addition, it cells pronounced phototropism, expressed responses light pulse purposefully move towards form phototaxis. Further observations majority visible field micrometry about 46 microns size average quantitative content 4,5 million one milliliter (culture) indicator optical density studied after 14 days medium increased by end little more than times, indicates sufficiently high value Beijer. culture.
