Microalgae Biomass Modelling and Optimisation for Sustainable Biotechnology – A Concise Review

Ugya Adamu Yunusa, Meguellati Kamel

Journal of Ecological Engineering

Vol. 23, nr 9

The autotrophic forms of microalgae are referred to as "efficient biological factories", because they play a significant role in CO2 removal from the atmosphere by utilizing it for the process of photosynthesis. The industrial application of microalgae biomass includes the production of cosmetics, health products, fertilisers, biofuel, feeds, and food. Microalgae biomass is also an important tool used in the treatment of wastewater. The current review is aimed at reviewing the progress and prospects of microalgae resource modelling and optimisation as a tool for sustainable biotechnology. The mechanism of biomass production by microalgae tends to vary according to whether the microalgae are autotrophic, heterotrophic, or mixotrophic organisms. In the current study, the modelling and optimisation of microalgae biomass production were discussed, as well as the modelling of CO2 sequestration, light intensity, nutrients, and photobioreactor. The role of microalgal biomass production in attaining sustainable biotechnology has also been extensively studied. Microalgae are an emerging tool used in the phycoremediation of wastewater and reduction of high CO2 level. The modelling and optimisation of microalgae biomass production will help to upscale the production of the microalgal based fuel and bioproducts from model scale to the money-making level.

A comprehensive assessment of dendrological resources for the formation of forest reclamation complexes is a process of qualitative and quantitative expansion of economically important plants and a scientifically based choice of the best possible option. The development of methods for improving the bioresources of degraded landscapes is aimed at the adaptive organization of land use in forestry and water management, recreation, urban planning, landscaping of settlements based on a comprehensive assessment of dendrological resources and increasing their biodiversity. The Federal Research Center of Agroecology of the Russian Academy of Sciences for a long period of its existence has created a network of experimental stations (cadastre No. 34:34:000000:122, 34:34:060061:10; Nizhnevolzhskaya station for the selection of tree species; 34:36:000014:178; West Siberian AGLOS; 22:23:010003:0014; Volga AGLOS; No. 63:23:0908001:0002) with dendrological collections located in different soil and climatic zones (Altai Krai, Samara and Volgograd regions) – typical areas of the arid zone with stable and moderate (in some years acute) summer moisture deficiency.
