    • Disclosed are methods that can advantageously utilize the natural consumptive and conversion processes of an aquatic organism culture system to concentrate and separate microbial plant-generated lipids. For instance, an aquatic organism culture can be maintained and/or grown upon an algal biomass. The natural conversion processes of the animals allows for uptake and processing of the components of the algal biomass into animal lipid. The aquatic animal culture can then be easily harvested such that a high percentage of the converted algal-generated lipid can be extracted using a low cost, simple and quick process. The disclosed processes provide an efficient oil production, conversion and recovery system that can be economically scaled up for use in, for example, integrated bioenergy and biodiesel production.
    • 公开了可以有利地利用水生生物培养系统的天然消耗和转化过程来浓缩和分离微生物植物产生的脂质的方法。 例如,可以在藻类生物质上维持和/或生长水生生物培养物。 动物的自然转化过程允许将藻类生物质的成分吸收和加工成动物脂质。 然后可以容易地收获水生动物培养物,使得可以使用低成本,简单和快速的方法提取高百分比的经转化的藻类产生的脂质。 所公开的方法提供了有效的石油生产,转化和回收系统,其可以经济地扩大用于例如集成的生物能源和生物柴油生产。

    • Disclosed are methods, materials and systems that can be used to determine qualitatively or quantitatively the level of uranium contamination in water samples. Beneficially, disclosed systems are relatively simple and cost-effective. For example, disclosed systems can be utilized by consumers having little or no training in chemical analysis techniques. Methods generally include a concentration step and a complexation step. Uranium concentration can be carried out according to an extraction chromatographic process and complexation can chemically bind uranium with a detectable substance such that the formed substance is visually detectable. Methods can detect uranium contamination down to levels even below the MCL as established by the EPA.
    • 公开了可用于定性或定量测定水样中铀污染水平的方法,材料和系统。 有利地,所公开的系统相对简单和成本效益。 例如,所公开的系统可以由具有很少或根本没有化学分析技术训练的消费者使用。 方法通常包括浓缩步骤和络合步骤。 铀浓度可以根据提取色谱法进行,络合可以用可检测物质化学地结合铀,使形成的物质在目视上可见。 方法可以将铀污染检测到甚至低于EPA建立的MCL水平。
