Biogenic hydrogen and methane production from Chlorella vulgaris and Dunaliella tertiolecta biomass
BACKGROUND Microalgae are a promising feedstock for biofuel and bioenergy production due to their high photosynthetic efficiencies, high growth rates and no need for external organic carbon supply. In this study, utilization of Chlorella vulgaris (a fresh water microalga) and Dunaliella tertiolecta (a marine microalga) biomass was tested as a feedstock for anaerobic H2 and CH4 production. RES...
متن کاملIsolation of Intact Chloroplasts from Dunaliella tertiolecta.
Cells of Dunaliella tertiolecta from the log phase of growth were broken by rapid extrusion at low pressure through a Yeda press and the chloroplasts were isolated by centrifugation through a Percoll gradient. Osmolarity of the growth media, the suspending media, and the Percoll gradient was kept identical to minimize change in chloroplast volume and mitochondrial entrapment. The isolated intac...
متن کاملNitrogen-induced metabolic changes and molecular determinants of carbon allocation in Dunaliella tertiolecta
Certain species of microalgae are natural accumulators of lipids, while others are more inclined to store starch. However, what governs the preference to store lipids or starch is not well understood. In this study, the microalga Dunaliella tertiolecta was used as a model to study the global gene expression profile regulating starch accumulation in microalgae. D. tertiolecta, when depleted of n...

متن کاملStudy of the inhibitory effect of the media culture parameters and cell population to increase the biomass production of Dunaliella tertiolecta
Microalgal growth curve, after the exponential phase, shows a stationary phase where algalbiomass production is inhibited and remains constant by some factors such as nutrientdepletion and intrinsic behavior. The present study is concerned with evaluating effects ofthe culture medium condition and intrinsic behavior on biomass production by Dunaliellatertiolecta. To this end, effect of pH, nutr...
