“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 کاملOutdoor Cultivation of the Biodiesel Promising Microalga Scenedesmus obliquus in Municipal Wastewater: A Case Study
Despite the promising research findings on microalgae as a feedstock for biodiesel, reduction of its production cost is still a challenge. One possible solution to overcome this problem is outdoor biomass production using wastewater as a growth medium. The present study aimed to evaluate the climate key parameters for Scenedesmus obliquus outdoor biomass production during different seasons, as ...
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 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 ...
متن کاملIsothermal and non-isothermal torrefaction characteristics and kinetics of microalga Scenedesmus obliquus CNW-N.
Isothermal and non-isothermal torrefaction characteristics and kinetics of microalga Scenedesmus obliquus (S. obliquus) CNW-N are studied using thermogravimetric analysis. The pyrolysis of S. obliquus CNW-N with increasing temperature is characterized by four-stage decomposition. Depending on the torrefaction temperature, light, mild, and severe torrefaction from the weight loss and the maximum...
