Abstract. Nannochloropsissp. has been identified as a promising feed stock for biodiesel production in recent years. Nannochloropsis sp. have high lipid content between 31-68 % of dry biomass weight. Mutagenesis induced by Gamma 60 Co irradiation can be utilized to alter Nannochloropsis sp. characteristic to get microalgae mutant strain that can produce a higher lipid content than the wild strain. The aim of this research was to know the effect of gamma 60 Co irradiation to the biomass, lipid content and fatty acid compotition of Nannochloropsis sp. microalgae. In this research, irradiation was done in different doses there were 0, 2, 4, 6 and 10 Gray (Gy). Measuring microalgae biomass and lipid content were done in late exponential phase at the end of each treatment. Research design used is random complete with 95 % confident level for quantitative analysis based on biomass and lipid content. Fatty acid compotition was analyzed by gas chromatography-mass spectrometry (GC-MS). Results showed that gamma irradiated gave an effect on lipid content and fatty acid profile of Nannochloropsis sp. Tukey test showed total lipid content of control micoalgae (0 Gy) was significat different with 10 Gy irradiated microalgae, but no significant different with 2,4 and 6 Gy irradiated microalgae. The highest lipid content were found in 10 Gy irradiated microalgae equal to 62.65 %. Fatty acid profile of 10 Gy irradiated Nannochloropsis sp. had 9 fatty acids while control Nannochloropsis sp. had 6 fatty acids.

“…Although the membrane technology is relatively new, it requires high energy during separation, and it is widely known for its poor selectivity [129][130][131][132][133][134][135]. This poses a major disadvantage for CO 2 capture using membranes [136][137][138]. More so, this technology uses either inorganic ceramic membranes or organic polymeric membranes [139,140].…”

Abstract:The global atmospheric concentration of anthropogenic gases, such as carbon dioxide, has increased substantially over the past few decades due to the high level of industrialization and urbanization that is occurring in developing countries, like South Africa. This has escalated the challenges of global warming. In South Africa, carbon capture and storage (CCS) from coal-fired power plants is attracting increasing attention as an alternative approach towards the mitigation of carbon dioxide emission. Therefore, innovative strategies and process optimization of CCS systems is essential in order to improve the process efficiency of this technology in South Africa. This review assesses the potential of CCS as an alternative approach to reducing the amount CO 2 emitted from the South African coal-fired power plants. It examines the various CCS processes that could be used for capturing the emitted CO 2 . Finally, it proposes the use of new adsorbents that could be incorporated towards the improvement of CCS technology.
