Biofixation of Carbon dioxide by Chlamydomonas sp. in a Tubular Photobioreactor

Biofixation of Carbon Dioxide from Kerosene Combustion and Biomass Production by Spirulina

  Background and purpose: CO2 is the main cause of greenhouse effect. Previous studies have shown that CO2 in methane and coal flue gas can lead to microalgae growth. The aim of this research was to study the CO2 biofixation by Spirulina and injecting kerosene flue gas. Materials and methods: A photo bioreactor was fabricated in which kerosene flue gas and air were separately injected. The ph...

Vertical tubular photobioreactor for semicontinuous culture of Cyanobium sp.

We evaluated the kinetic culture characteristics of the microalgae Cyanobium sp. grown in vertical tubular photobioreactor in semicontinuous mode. Cultivation was carried out in vertical tubular photobioreactor for 2 L, in 57 d, at 30 °C, 3200 Lux, and 12 h light/dark photoperiod. The maximum specific growth rate was found as 0.127 d(-1), when the culture had blend concentration of 1.0 g L(-1),...

Some characteristics of microalgae isolated in Taiwan for biofixation of carbon dioxide

To contribute the biological mean of CO2 fixation, more than 200 microalgal isolates were screened from lakes, ponds, sediments, hog wastewater, paddy fields, hot springs, and seawater in Taiwan. Two unicellular microalgae, Chlorella sp. NTU-H15 and Chlorella sp. NTU-H25, were isolated from hog wastewater. In the laboratory, they were able to grow up even in aeration containing CO2 up to 40% an...

Proposed carbon dioxide concentrating mechanism in Chlamydomonas reinhardtii.

Tubular photobioreactor design for algal cultures.

Principles of fluid mechanics, gas-liquid mass transfer, and irradiance controlled algal growth are integrated into a method for designing tubular photobioreactors in which the culture is circulated by an airlift pump. A 0.2 m(3) photobioreactor designed using the proposed approach was proved in continuous outdoor culture of the microalga Phaeodactylum tricornutum. The culture performance was a...
