Seaweed has long been an important kitchen ingredient and a functional food material. Microalgae have attracted the same attention as seaweed from food, pharmaceutical and cosmetic companies because several algae contain unique functional materials. Industry application of algae requires the selection of useful algal species, evaluation of their features and monitoring of their quality in culture. Taking Chlorella for example, this chapter presents a method using flow cytometry (FCM) to assess not only the number of algae but also algal quality. First, Chlorella was cultured in media containing eluate from steel slag as an experimental factor and trace metals. After the treatment of algae with eluate, the number and physiological features of algae were evaluated, respectively, using hemocytometry and FCM. Results show that eluate from slag induced neither lethality nor growth inhibition. Coupled with hemocytometry, FCM was used to estimate vigorous and aberrant algal status. Consequently, the eluate did not give rise to algae stresses. Interestingly, the addition of slag eluate increased the amounts of the carbonate species. The increase in the carbonate species actually triggered the potential increase in aqueous CO 2 for photosynthesis, eventually inducing algal proliferation. These analyses can support evaluation of algal features and maintenance of their quality for industry application.

“…As an alternative to the conventional treatment methods, microalgae are suggested to remove the nutrients from wastewater [35]. The use of microalgae or macro algae (seaweeds) to remove pollutants and nutrients from the wastewater is called phycoremediation.…”

“…Microalgae are used extensively in the treatment of waste waters because they can sequester large amounts of nutrients and other pollutants. At present, there are many municipal and industrial waste treatment plants that use microalgae in oxidation ponds to biodegrade wastes [35], [40] However, there is no control over the algal species and, with few exceptions, no harvesting of the algal biomass generated in these ponds.…”

In this mini review it is to focus that how can pollutants be removed from the environment by utilizing microalgae which are deliberately increasing and causing hazardous effects to our environment. Microalgae are sunlight-driven cell factories that convert carbon dioxide to potential biofuels, foods, feeds and high-value bioactives. Various types of pollutants continuously causing damage to the environment and after a long-term observation it is found that there is a best option of using microalgae in different techniques for reducing environmental pollutants. Since, versatile species of microalgae has been a part in reduction and removal of environmental pollutants as we observed in different bioremmedial techniques such as in waste water treatment plants, heavy metal removal techniques, bio-degradation of azo-dyes, phenol and other organic aromatic compounds which are dangerous to the environment. It is reappraised that one of microalgae specie which is named as chlorella vulgaris is found to be very effective in removing of heavy metals, waste water treatment and also in biodegradation of azo-dyes. This article basically explained the usefulness of using microalgae for the remediation of pollutants.

“…As microalgas, pela extensa variedade de espécies e propriedades intrínsecas, demonstram grande potencial para exploração comercial. Dentre os principais componentes de suas células, destaca-se seu teor de lipídios, que é matéria prima para a produção de biodiesel (CAMPANELLA et al, 2001, MALLICK, 2002CHISTI, 2007;AMARO et al, 2012).…”

RESUMOUm dos materiais alternativos mais investigados atualmente para a produção de biodiesel são as microalgas. O presente trabalho teve como objetivo a avaliação do método de transesterificação enzimática in situ da microalga Desmodesmus sp. em solvente orgânico, acompanhando a reação através do monitoramento on-line com sonda de infravermelho e cromatografia gasosa. Dois ensaios foram realizados em condições distintas para efeito comparativo. Baseado nos resultados obtidos por espectroscopia e cromatografia, bem como nas propriedades calculadas a partir do perfil cromatográfico, pode-se concluir que é possível à produção de biodiesel in situ a partir de biomassa de microalgas, reduzindo a etapa de extração de óleo. Palavras-chave:Microalga. Desmodesmus sp. Biodiesel. Transesterificação in situ. Espectroscopia de infravermelho. Cromatografia gasosa. ABSTRACTOne of the most investigated alternative materials for the production of biodiesel is microalgae. The present work had the objective of evaluating the in situ enzymatic transesterification method using the microalga Desmodesmus sp. in organic solvent, following the reaction through online monitoring with infrared spectroscopy and gas chromatography. Two experiments were carried out under different conditions for comparative effect. Based on the results obtained by spectroscopy and chromatography, as well as the properties calculated from the chromatographic profile, it can be concluded that it is possible to produce in situ biodiesel from microalgae biomass, eliminating the oil extraction step.
