The marine cyanobacteria Oscillatoria salina Biswas, Plectonema terebrans Bornet et Flahault and Aphanocapsa sp. degraded Bombay High crude oil when grown in artificial seawater nutrients as well as in plain natural seawater. Oil removal was measured by gravimetric and gas chromatographic methods. Around 45-55% of the total fractions of crude oil (containing 50% aliphatics, 31% waxes and bitumin, 14% aromatics and 5% polar compounds) were removed in the presence of these cultures within 10 days. Between 50% and 65% of pure hexadecane (model aliphatic compound) and 20% and 90% of aromatic compounds (anthracene and phenantherene) disappeared within 10 days. Mixed cultures of the three cyanobacterial species removed over 40% of the crude. Additionally, these cultures formed excellent cyanobacterial mats when grown in mixed cultures, and thus have the potential for use in mitigating oil pollution on seashores, either individually or in combination.
海洋蓝藻盐生颤藻(Oscillatoria salina Biswas)、钻孔席藻(Plectonema terebrans Bornet et Flahault)和隐球藻属(Aphanocapsa sp.)在人工海水营养物以及普通天然海水中生长时,能够降解孟买高硫原油。通过重量法和气相色谱法测定原油去除率。在这些培养物存在的情况下,10天内原油总馏分(含50%脂肪族、31%蜡和沥青、14%芳烃和5%极性化合物)的约45%-55%被去除。10天内,50%-65%的纯十六烷(典型脂肪族化合物)和20%-90%的芳烃化合物(蒽和菲)消失。这三种蓝藻的混合培养物去除了超过40%的原油。此外,这些培养物在混合培养时形成了优良的蓝藻席,因此无论是单独使用还是组合使用,都有减轻海岸油污的潜力。
