a b s t r a c tThe pretreatment operations (drying, cell disruption and oil extraction) of microalgae biomass to the lipids extraction are important steps to the product quality and production cost. In this study, the lipids from Spirulina were obtained by different methods of biomass drying (tray and spouted bed), cell disruption (microwave, autoclaving and milling) and solvent extraction (hot and cold). The average content of lipids extracted by the cold method, using polar solvents, was of 5.8 ± 0.6 g 100 g À1 . The spouted bed drying with cell disruption by milling achieved the best performance with the hot extraction method. Under these conditions, the TBA value was of 0.57 ± 0.09 mg MDA kg À1 . FT-IR spectra and thermal analysis indicated that the hot extraction resulted in a more purified lipid extract than the cold extraction. The Brimberg model showed the best fit to the lipid extraction kinetics and the activation energy in the best conditions was of 6.11 ± 1.41 kJ mol À1 .

“…The isolation of these alkaloids 2,3 is relatively simple and their synthesis has been described by several laboratories (ref. 18,19 For better transition of PR and AL from solid samples to an appropriate organic solvent, the extraction can be improved at higher temperature, in ultrasonic bath (ultrasound-assisted extraction), 17,20 using Soxhlet apparatus, 21 special solid-liquid extractor, [22][23][24] and/or microwave-assisted extraction procedures. On this basis, the pure compounds (model standard solutions) are available for confirmation of their identity in biological samples and validation of analytical procedures.…”

“…On the other hand, we used pseudo-first order and pseudo-second order kinetic models to investigate the extraction of biosurfactant from L. pentosus cells in the absence of NaCl at different temperatures. This is the first kinetic study of the extraction of biosurfactant from microbial cells, although Rakotondramasy-Rabesiaka et al [30] applied a pseudo-second order model to explain the solid-liquid extraction of protopine from F. officinalis plant cells.…”

A cell-bound biosurfactant produced by Lactobacillus pentosus was obtained under eco-friendly conditions and used directly as an emulsifying agent in order to stabilize fluorene/water emulsions. The biosurfactant was extracted from L. pentosus cells with an aqueous phosphate buffer solution in the absence of NaCl. This is important because most the cell-bound biosurfactants are extracted in the presence of NaCl, which is considered highly phytotoxic. A pseudo-second order kinetic model best described the batch extraction of the biosurfactant from cells. As expected, the initial extraction rate of the biosurfactant increased with the temperature. Calculation of the activation energy with the Arrhenius equation yielded a positive value, indicating that the process is endothermic. The aqueous solution containing the biosurfactant was able to stabilize fluorene/water emulsions, with relative emulsion values of 62.2 % after 7 days of emulsion formation.
