Production of biodiesel from wastewater grown Chlorella minutissima

چکیده
The present study has been undertaken to assess integrated algal harvesting in sewage wastewater for biodiesel feedstock. Chlorella minutissima microalgae are grown in wastewater from local hotel sewage drain and produced biomass is used to produce biodiesel. C. minutissima effectively removes the wastewater nutrients nitrogen and phosphorus with the 99.19% and 96% removal respectively. Content of oil in produced algal biomass is drastically reduced i.e. 4% in response to 57% of total dry biomass reported in literature. The extracted oil mainly consists of small chain fatty acids (C-16:0, C-18:1, C-18:2, C-18:3). Transesterification reaction shows that maximum fatty acid methyl ester (FAMEs) concentration is converted from free fatty acids of oil during 1-2 h at 65°C.

Much research has focused on growing microalgae for biofuel feedstock, yet there remain concerns about the feasibility of freshwater feedstock systems. To reduce cost and improve environmental sustainability, an ideal microalgal feedstock system would be fed by municipal, agricultural or industrial wastewater as a main source of water and nutrients. Nonetheless, the microalgae must also be tole...

Using algae as a feedstock for biodiesel has been considered for a number of years, but it has always had limitations, due mainly to the production methods used to grow and harvest the algae. In this project, we propose a novel attached growth method to produce the algae while recycling dairy farm wastewater using the microalga Chlorella sp. The first part of the work provided a feasibility stu...

Chlorella minutissima was co-cultured with Escherichia coli in airlift reactors under mixotrophic conditions (glucose, glycerol, and acetate substrates) to determine possible effects of bacterial contamination on algal biofuel production. It was hypothesized that E. coli would compete with C. minutissima for nutrients, displacing algal biomass. However, C. minutissima grew more rapidly and to h...
