Due to the adaption to environmental stress, biomasses of microalgae and cyanobacteria contain high-value pigments and phenolic compounds with antioxidant capacity to be used as ingredients for food, cosmetics, and pharmaceuticals. To expand the current state of knowledge about microalgae and cyanobacteria as sources of high-value compounds biomasses and extracts of 13 microalgal and cyanobacterial species of the four divisions, namely Chlorophyta, Rhodophyta, Cyanophyta and Diatoms, with regards to their antioxidant capacity, were characterized. Moreover, cell disruption prior to extraction of the slurry of the alga Acutodesmus obliquus was investigated for increasing yields of compounds with antioxidant capacity. The total chlorophyll and carotenoids contents of the tested green algae was with up to 60 mg g⁻¹ and 12 mg g⁻¹, respectively, substantially higher compared to the other algae. Results revealed that aqueous extraction is effective for extracting phenolic compounds from biomass. The quantity of phenolic compounds in the extracts revealed no superior species. Nevertheless, Neochloris oleobundans, Phormidium sp., and Wilmottia murravi can be recommended as species with high contents in phenolic compounds (>20 mg gallic acid eq. g⁻¹). Phormidium ambiquum and Phormidium sp. were the strains with highest contents in water-soluble compounds (12–14 μmol ascorbic acid eq. g⁻¹), while N. oleobundans and A. obliquus were the strains with highest contents in lipid-soluble compounds (60–80 μmol trolox eq. g⁻¹). Cell disruption prior to extraction doubled the yields of compounds with antioxidant activity, which underlines the necessity of an effective pre-treatment. Results of this study contribute to the proceeding towards a utilization of microalgal and cyanobacterial biomasses for the formation of high-value compounds with antioxidant properties and potential for food, cosmetic, and pharmaceutical industries.

由于适应环境压力，微藻和蓝细菌的生物质包含高价值的颜料和具有抗氧化能力的酚类化合物，可用作食品，化妆品和药品的成分。为了扩展关于微藻和蓝细菌作为高价值化合物生物质来源的知识的现状，并就其抗氧化能力进行了表征，对四类（即绿藻，红藻，蓝藻和硅藻）的13种微藻和蓝细菌物种的提取物进行了表征。 。此外，提取藻类斜纹奇藻的浆液之前会破坏细胞研究了增加具有抗氧化能力的化合物的收率的方法。被测绿藻的总叶绿素和类胡萝卜素含量分别高达60 mg g ^-1和12 mg g ^-1，比其他藻类高得多。结果表明，水提取对从生物质中提取酚类化合物有效。提取物中酚类化合物的含量没有显示出优良的种类。尽管如此，Neochloris oleobundans，席藻属，和Wilmottia murravi可推荐作为与酚类化合物高含量物种（> 20毫克没食子酸当量克。^-1）。纤细席ambiquum和纤细席sp。是在水溶性化合物中含量最高的菌株（12–14μmol抗坏血酸当量g ^-1），而油橄榄猪笼草和斜叶曲霉是在脂溶性化合物中含量最高的菌株（60–80μmoltrolox eq.g ^-1）。提取之前的细胞破裂使具有抗氧化活性的化合物的产量翻了一番，这突出了有效预处理的必要性。这项研究的结果有助于微藻和蓝细菌生物质的利用，以形成具有抗氧化特性并在食品，化妆品和制药工业中具有潜力的高价值化合物。
