Thermodynamic assessment of algal biodiesel utilization

Sorguven, Esra; Özilgen, Mustafa - In: Renewable Energy 35 (2010) 9, pp. 1956-1966

In late 1990's some microalgae were found to be capable of producing lipids from carbon dioxide via photosynthesis with thirty times the efficiency of plants in terms of the amount of oil produced per unit area of the land allocated. This process raised hope in the fight against environmental...

Isolation of a new highly CO2 tolerant fresh water Microalga Chlorella sp. KR-1

Sung, K.D.; Lee, J.S.; Shin, C.S.; Park, S.C. - In: Renewable Energy 16 (1999) 1, pp. 1019-1022

A fresh-water microalga, which has tolerance to high concentrations of CO2, was isolated. The KR-1 strain was identified to be as genus Chlorella. Though Chlorella KR-1 showed maximum growth at 10% CO2, the strain showed a good growth rate up to 50% CO2. The results indicated the feasibility of...
