Microalgae are one of the most promising renewable energy sources with environmental sustainability. The surface free energy of microalgal cells determines their biofouling and bioflocculation behavior and hence plays an important role in microalgae cultivation and harvesting. To date, the surface energetic properties of microalgal cells are still rarely studied. We developed a novel spectropho...

In this study, effect of different 2,4 -dichlorophenoxyacetic acid (2,4-D) concentrations (0.0, 9.10(-5), 9.10(-4), 9.10(-3) and 9.10(-2) mM) on growth rate, content of protein and chlorophyll-a in Chlorella vulgaris and Spirulina platensis cells was investigated. The most stimulatory effect on growth rate, protein and pigment ratio of C. vulgaris and S. platensis was observed at 9.10(-4) mM co...

Accumulation of intra-cellular phosphate, as polyphosphate, was measured when the microalga Chlorella vulgaris was immobilized in alginate with either of two wild-type strains of the microalgae growth-promoting bacterium Azospirillum brasilense or their corresponding IAA-attenuated mutants. Wild type strains of A. brasilense induced higher amounts of intra-cellular phosphate in Chlorella than t...

"Alginate/silica hybrid materials for immobilization of green microalgae Chlorella vulgaris for cellbased sensor arrays" (2014). Thin layers and patterned dot arrays of sodium alginate containing living microalgal cells were deposited onto glass carriers which were subsequently gelled using amino-functionalized silica sol to obtain reinforced alginate hydrogels. The resulting alginate/silica hy...

The aim of this work was to evaluate the influence Chlorella vulgaris ( C. ) additions on printability cereal-based doughs. Increasing levels incorporation (2–30 % w/w) were tested and a limit (30 %) for printing reached. Evaluation conducted based rheology texture properties doughs shape fidelity 3D printed combination assessment led development maps, where grouped into different (1–3), provid...

The growth response of Chlorella vulgaris was studied under varying concentrations of carbon dioxide (ranging from 0.036 to 20%) and temperature (30, 40 and 50 degrees C). The highest chlorophyll concentration (11 microg mL(-1)) and biomass (210 microg mL(-1)), which were 60 and 20 times more than that of C. vulgaris at ambient CO(2) (0.036%), were recorded at 6% CO(2) level. At 16% CO(2) level...
