В монографии представлены результаты теоретических и экспериментальных исследований роста культур микроводорослей. Монография основа на серии статей под общим названием «Простейшие модели роста микроводорослей». Уделено внимание количественным аспектам роста микроводорослей в накопительной, квазинепрерывной и непрерывной культуре. Рассмотрены механизмы ограничения роста микроводорослей различными факторами среды.Монография представляет интерес для специалистов по исследованию роста микроводорослей, а также альгобиотехнологов. Также будет полезна студентам и аспирантам, обучающихся по биологическим и биофизическим специальностям.
Productional and biochemical characteristics of green alga Dunaliella salina (Dunal) Teodoresco were studied during pilot cultivation at the southwest of Crimean Peninsula, Russia. Two-phase cultivation was carried out in ponds located in the greenhouse module. In the "green" phase, biomass concentration reached 1.2 g/l, with maximum cell density of 1.69•10 6 cell/ml and the maximum productivity of 0.08 g/(l•day) (7 g/(m 2 •day)). Twofold culture dilution was applied for carotenogenesis induction. The maximum cell density in the "red" phase was 0.84•10 6 cell/ml, while biomass reached 0.95 g/l. Mean net carotenoid accumulation rate at the second stage (1-6 day) was 0.65 mg/(l•day). Carotenoids content in culture doubled compared to initial values and reached about 20 mg/l or 800 mg/m 2. Carotenoids/chlorophyll a ratio of 11.6 was observed by the end of the "red" phase. Night biomass loss was higher in the "red" phase (up to 9.5% of biomass) compared to the "green" phase (up to 5.6%). Optimal duration of both the first and the second cultivation stages was found to be 10-12 days for the studied weather conditions, which enables production of 3 g of carotenoids from 1 m 2 (100 l) of starter culture. In conclusion, Crimea is a prospective region for D. salina algobiotechnology.
A new explanation for linear growth microalgae culture density is proposed. Equations describing the dependence of light absorption coefficient and the specific rate of biomass synthesis on chlorophyll concentration are obtained. The specific extinction coefficient for Tetraselmis virilis culture (0.008 m-2 · mg chlorophyll a) is calculated.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
