“…This was in accordance with that reported by Al-Garni et al (2009). Conversely other results reported the success of the dried biomass in removal of cadmium from an aqueous solution (Volesky, 1990;Zhou and Kiff, 1991;Bayramoglu et al, 2006). The biosorption by the two forms was dependent on the fungal species and maybe on its strains.…”

“…Some other studies reported that most of the biosorbion was achieved in 5 to 15 min. The fluctuation of equilibrium period was recorded by many workers and depended in many factors of which the type and nature of the biomass, pH, metal ions, and physicochemical properties of the biosorption process (Saglam et al, 1999;Kacar et al, 2000;Abu Al-Rub et al, 2004;Herrero et al, 2005;Bayramoglu et al, 2006;EL-Sherif et al, 2008;Parameswari et al, 2009;Al Garni et al, 2009).…”

“…wastewater), via both metabolically mediated and physico-chemical pathways (Radway et al 2001;Gupta and Rastogi 2008). Microalgae have proven their high metal-binding capacities (Schiewer and Volesky 2000;Bayramoglu et al 2006;Muñoz et al 2006), even when compared to such other biological entities as bacteria, fungi and yeasts , owing to the presence of polysaccharides, proteins and/or lipids on the surface of their cell walls: these contain charged functional groups (e.g. amino, hydroxyl, carboxyl and sulphate) that can attract, and thus act as binding sites for metals (Bayramoglu et al 2006;Gupta and Rastogi 2008).…”

Aquatic environments are often exposed to toxic heavy metals, which gain access to the food chain via microalgae and may cause severe problems at higher trophic levels. However, such a metabolic specificity can be taken advantage of in bioremediation strategies. The potential of a novel wild strain of Scenedesmus obliquus, previously isolated from a heavy metal-contaminated site in northern Portugal, to remove Zn from aqueous solutions was thus studied, using several initial concentrations. The removal extent reached its maximum by 1 day: 836.5 mg Zn/g biomass, at the initial concentration of 75 mg/L, mainly by adsorption onto the cell surface. Comparative studies encompassing a commercially available strain of the same microalgal species led to a maximum removal extent of only 429.6 mg Zn/g biomass, under identical conditions. Heat-inactivated cells permitted a maximum removal of 209.6 mg Zn/g biomass, at an initial concentration of 50 mg Zn/L. The maximum adsorption capacity of Zn, estimated via Langmuir's isotherm, was 330 mg Zn/g biomass. Finally, Zn removal was highest at pH 6.0-7.0. It was proven, for the first time, that such a wild microalga can uptake and adsorb Zn very efficiently, which unfolds a particularly good potential for bioremediation. Its performance is far better than similar (reference) species, especially near neutrality, and even following heat-treatment.

Рассматривается иммобилизация клеток оксигенных фототрофных микроорганиз-мов -цианобактерий и эукариотических микроводорослей -в природе и в искусствен-ных системах. В обзоре подчеркивается, что существование клеток микроорганизмов в прикрепленном состоянии, например, в составе биопленок, является широко распро-страненной в природе стратегией, обеспечивающей выживание клеток. Таким образом, искусственно иммобилизованные клетки оксигенных фототрофных микроорганизмов можно рассматривать как особую группу биомиметических материалов. Особое внимание уделено изучению влияния различных способов иммобилизации на физиологическое состояние клеток цианобактерий и микроводорослей, их устойчивость к стрессовым воз-действиям, а также продуктивность культур, находящихся в иммобилизованном состоя-нии. В обзоре проводится анализ преимуществ и недостатков современных методов им-мобилизации и используемых в настоящее время носителей. Освещаются возможности применения иммобилизованных культур оксигенных фототрофных микроорганизмов в различных областях биотехнологии, таких как получение биомассы и ценных метаболи-тов, сбор биомассы, очистка водных акваторий и сточных вод от тяжелых металлов, из-бытка биогенных элементов и органических загрязнителей.
