Intensive culture of diatoms Cylindrotheca closterium (Ehrenb.) Reimann et Lewin

Abstract

Growth characteristics of a diatom microalgе Cylindrotheca closterium are investigated. Cylindrotheca closterium cultivated on nutrient mediums which were received by proportional increase all biogenous elements concentration of the environment F. It is shown that culture efficiency increases due to proportional increase of the biogenous elements up to 20 F in a nutrient medium. The maximum efficiency of this microalga is received at cultivation on a nutrient medium 20 F and made 1.74 g/l.
