Abstract:
... This paper presents a strategy for isolation, identification and evaluation of microalgae strains synthesizing biologically active compounds (BAC) with antimicrobial activity against food-borne and other pathogens. Water samples containing microalgae were initially submitted to the enrichment process, followed by standard procedure for obtaining pure culture. Purified DNA from the microalgae isola ...

Abstract:
... Switchable solvents with hydrophobicities that can be reversibly changed were evaluated as single solvents for oil extraction from wet biomass. Three switchable solvents, N,N-dimethylcyclohexylamine (DMCHA), N-ethylbutylamine (EBA), and dipropylamine, were used to extract oil from the undisrupted wet paste of harvested Chlorella sp. microalgae. The oil extraction yields for the three solvents were ...

Abstract:
... Although various methods have been developed for microalgae harvesting, problems such as chemical toxicity, low efficacy, low flexibility, and high cost, still remain with the current methods. In the present study, an effective biological separation method has been developed to harvest microalgae via immobilization on exogenous fungal mycelium. Fungal mycelium was added into microalgae culture and ...

Abstract:
... In situ transesterification of lipids in algal biomass reduces the number of unit operations by producing alkyl esters (biodiesel) directly from the lipid phase. The production of alkyl esters by in situ transesterification from marine microalgae Nannochloropsis oculata and freshwater microalgae Chlorella sp. was evaluated using different catalysts and biomass moistures. Three homogenous catalysts ...

Abstract:
... An attempt to scale-up a biodiesel production plant from a heterotrophic culture of microalgae, together with an evaluation of feasibility is performed in this article. The plant employs the microalgae Chlorella protothecoides to obtain biomass. The subsequent oil extraction is done with supercritical carbon dioxide. Based on previous studies, it was possible to determine the mass and energy balan ...
