“Rational” Management of Dichlorophenols Biodegradation by the Microalga Scenedesmus obliquus
The microalga Scenedesmus obliquus exhibited the ability to biodegrade dichlorophenols (dcps) under specific autotrophic and mixotrophic conditions. According to their biodegradability, the dichlorophenols used can be separated into three distinct groups. Group I (2,4-dcp and 2,6 dcp - no meta-substitution) consisted of quite easily degraded dichlorophenols, since both chloride substituents are...
متن کاملWaste utilization and biodiesel production by the green microalga Scenedesmus obliquus.
Scenedesmus obliquus was cultivated in three types of waste discharges to couple waste treatment with biodiesel production. The lipid pool accumulation was boosted to 1.0 g liter(-1) against 0.1 g liter(-1) for the control. The waste-grown S. obliquus showed an increase in the content of the saturated fatty acid pool, which is desirable for good-quality biodiesel.
متن کاملBiodiesel production by the green microalga Scenedesmus obliquus in a recirculatory aquaculture system.
Biodiesel production was examined with Scenedesmus obliquus in a recirculatory aquaculture system with fish pond discharge and poultry litter to couple with waste treatment. Lipid productivity of 14,400 liter ha(-1) year(-1) was projected with 11 cultivation cycles per year. The fuel properties of the biodiesel produced adhered to Indian and international standards.
متن کاملFeasibility of CO2 mitigation and carbohydrate production by microalga Scenedesmus obliquus CNW-N used for bioethanol fermentation under outdoor conditions: effects of seasonal changes
BACKGROUND Although outdoor cultivation systems have been widely used for mass production of microalgae at a relatively low cost, there are still limited efforts on outdoor cultivation of carbohydrate-rich microalgae that were further used as feedstock for fermentative bioethanol production. In particular, the effects of seasonal changes on cell growth, CO2 fixation, and carbohydrate production...
متن کاملInfluence of phosphorus concentration on the growth kinetics and stoichiometry of the microalga Scenedesmus obliquus
The growth of the freshwater microalga Scenedesmus obliquus was studied at 30°C in a mineral culture medium with phosphorus concentrations of between 0 and 372 pro. The values for the specific growth rates, between So=0 #m and S,=298 pro, fitted a semistructured substrate-limitation model with #,,~ = 0.0466 h P.,,2 = 0.0256 h ~ and Ks = 0.2 ttm. The specific uptake rate of phosphorus reached a ...
