The review paper presents the use of algal extracts as safe and solvent-free components of plant growth biostimulants, dietary feed additives and cosmetics. Innovative technology that uses extracts obtained by supercritical CO₂ extraction, as a method of isolation of biologically active compounds from algal biomass, is presented. An important part of the complete technology is the final formulation of the product. This enabled realization of the further step which was assessment of the utilitarian properties of the extract-based products. The extracts were analysed for the presence of biologically active molecules (e.g., plant hormones, polyphenols) which provide useful properties such as antioxidant, antiviral, anti-inflammatory and antibacterial. The bio-products were tested in germination tests and underwent field trials to search for plant growth biostimulatory properties. Tests on animals (laying hens experiments) were conducted to assess pro-health properties of new dietary feed supplement. Another application were cosmetic formulations (dermatological tests). The results of the application tests were very promising, however further studies are required for the registration of the products and successful implementation to the market.
这篇综述论文介绍了藻类提取物作为植物生长生物刺激剂、饲料添加剂和化妆品中安全且无溶剂成分的应用。文中还介绍了一种创新技术，即利用超临界二氧化碳萃取获得的提取物，作为从藻类生物质中分离生物活性化合物的方法。完整技术的一个重要部分是产品的最终配方。这使得能够进一步评估基于提取物的产品的实用特性。对提取物进行了分析，以检测生物活性分子（如植物激素、多酚）的存在，这些分子具有抗氧化、抗病毒、抗炎和抗菌等有用特性。这些生物产品在发芽试验中进行了测试，并进行了田间试验以寻找植物生长生物刺激特性。对动物进行了测试（蛋鸡实验），以评估新型饲料补充剂的健康促进特性。另一个应用领域是化妆品配方（皮肤学测试）。应用测试的结果非常有前景，然而，为了产品注册和成功推向市场，还需要进一步的研究。
