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...

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...

An effective semi-continuous process was developed to grow a locally isolated green microalga Chlorella sp. on acidogenically digested swine wastewater in bench scale for improved algal biomass production and waste nutrient removal using central composite design (CCD). The influences of two key...

Raw biogas is a valuable renewable energy but usually requires upgrading. The mixed LED (light-emitting diode) light wavelengths achieved much better microalgae growth than that of the monochromatic. The best LED light wavelength mix ratio for both biogas upgrading and biogas slurry nutrient...

The biodiesel production from a naturally isolated strain of Chlorella in 2L bubble-column photobioreactor was studied. The microalgal strain was isolated from the rice paddy-field soil samples during a screening program. After 17days, at the end of exponential phase of growth, the total content...

Biodiesel as a biodegradable, sustainable and clean energy has worldwide attracted renewed and growing interest in topical years, chiefly due to development in biodiesel fuel and ecological pressures which include climatic changes. In the production of biodiesel from biomass, separation and...

In this study, both edible (coconut oil, palm oil, groundnut oil, and rice bran oil) and non-edible oils (pongamia, neem and cotton seed oil) were used to optimize the biodiesel production process variables like catalyst concentration, amount of methanol required for reaction, reaction time and...
