Microalgae have been shown to be a source of multiple bio-based products ranging from high value molecules commodities. Along with their potential produce large variety products, microalgae can also used for the depollution wastewaters different origins (urban, industrial, and agricultural). This paper is focused on importance harnessing bioremediation capacity treat in order develop industry (especially biofuel industry) find other alternatives classic wastewater treatment processes. The...

This study evaluates the feasibility of removing nutrients by microalgae Chlorella vulgaris, using urban wastewater as culture medium, namely effluent subjected to secondary biological treatment in a plant (WWTP). For this, laboratory experiments were performed batch cultures effect initial nitrogen and phosphorus concentrations on growth reduction nutrient performance C. vulgaris. The microalga was cultivated enriched containing different (1.3-143.5 mg x L(-1) P.PO4(3-)), ammonium...
This article proposes a kinetic model for wastewater photobiotreatment with microalgae (the PhBT model). The nutrient uptake, coupled the Verhulst growth model, is simple and useful tool to describe batch experiments of removal by microalgae. has been validated Chlorella vulgaris (C. vulgaris) grown in different synthetic media. provided information about nitrogen phosphorus limitation their luxury uptake during test. Productivity observed medium (0.17 g SS L(-1) d(-1)) was similar that...
Nitrogen and phosphorus concentration in the effluent of a wastewater treatment plant can vary significantly, which could affect growth kinetic chemical composition microalgae when cultivated this medium. The aim work was to study rate growth, nutrient removal carbon dioxide biofixation as well biomass Scenedesmus obliquus (S. obliquus) it is at different nitrogen ratio, from 1:1 35:1. A more homogeneous method for calculating productivities batch reactors proposed. proper N:P ratio...
Batch experiments were performed to study biomass growth rate, nutrient removal and carbon dioxide bio-fixation of the marine microalgae Chlorella stigmatophora. Four different cultures at salinities tested: wastewater (WW), synthetic (SWW), seawater (SW) diluted (DSW). Experimental results showed that stigmatophora grew satisfactorily in all culture media, except SWW where inhibition occurred. In cases, experimental data fitted Verlhust Logistic model (R2 > 0.982, p < or = 0.05). Maximum...
Hydroponic farms produce wastewater that need to be treated before being released into the environment. A three-step screening process (microplate, batch, and semi-continuous flasks experiments) initially designed select an efficient microalgae strain allowed isolation of a consortium naturally developed in hydroponic farm wastewater. During non-optimized experiments, best performing strain, Scenedesmus obliquus UTEX393 wastewater-born cultures achieved good average linear growth rate (0.186...
AbstractAbstractMicroalgae strains, Botryococcus braunii and Chlorella vulgaris were cultured in urban wastewater as monoalgal cultures together co-cultures; the same experiments performed synthetic growth medium to establish comparisons between both media. A fully crossed factorial design was used carry out experiment, resulting 18 tests, this procedure allowed development of regression models that defined experimental factors their interactions. Results indicated strains able grow...
In this key comparison anion calibration solutions of nitrate and nitrite were investigated. The mass fractions the anions in both about 1 g/kg. For 8 participants provided results; 3 analytical techniques used: ion chromatography, capillary electrophoresis coulometry after exchange. amount content was determined by 7 using one following techniques: titrimetry electrophoresis. institutes participated comparison: INTI (Argentina), KRISS (Korea), LNE (France), NIM (Pepole's Republic China),...
Abstract Microalgae are emerging as a promising feedstock for bioplastics, with Chlorella vulgaris yielding significant amounts of starch. This polysaccharide is convertible into thermoplastic starch (TPS), biodegradable plastic industrial relevance. In this study, we developed pilot-scale protocol extracting and purifying from starch-enriched biomass. From 430.3 ± 0.5 g (dry weight - DW) microalgae biomass containing 42.2 3.4 % starch, successfully extracted 205.8 1.2 DW purified extract...
The NENU2PHAR project is developing sustainable, biodegradable bio-based plastics from microalgae goal of this BBI-JU to develop across four years an innovative European value chain PHA (Polyhydroxyalkanoate) based sustainable and renewable resources: biomass selection bacteria strains. Eight PHA-based products with their respective end-of-life scenarios were developed benchmarked fossil-based counterparts.
