“…Some species can control the membrane transport of heavy metals towards, or their active efflux from, the cell [63,64]. Metal ion resistance via transport and passive mechanisms leading to extracellular precipitation is more characteristic for prokaryotes [65], whereas sequestration mechanisms are mainly adopted by eukaryotes [66].…”

A promising new dimension in the field of biotechnology is the use of microorganisms for the production of inorganic nanoscale particles. The interest in nanotechnology is provoked by the unique properties of nanostructured materials and their potential fields of application ranging from medicine to electronics. This review article presents a systematic overview of the microorganisms capable of producing nanoparticles, and describes cellular mechanisms and outlines cultivation conditions that turn this process into a successful synthetic pathway.

“…Numerous studies have revealed that all yeast genera can accumulate different heavy metals, but particularly interesting is the capability of accumulating significant amounts of highly toxic metals [64]. Cells able to grow in media with high metal ion concentrations are called resistant.…”

“…Removal of heavy metals, and radionuclides such as thorium and uranium from aqueous solutions using biological materials and various microorganisms was investigated in several studies. Natural bio-adsorbents such as seaweeds (Yang and Volesky 1999), bacteria (Li et al 2016), yeast (Breierova et al 2002), fungi (Hou et al 2016), algae (Al-Qunaibit, Khalil, and Al-Wassil 2005) and marine sponges (Hansen, Weeks, and Depledge 1995;Maloubier et al 2015) were used in these studies. Biosorption process could be considered as a combined method of passive fusion (coagulation) process independent from the metabolism, and physical and/or chemical adsorption, ion exchange, coordination, complexation, chelate formation and micro-precipitation processes.…”

The biosorption of heavy metals, radionuclides, uranium and thorium for the recovery or removal from aqueous systems using various micro-organisms and biological substances has been investigated by several groups of workers. In this paper, the uptake of uranium (VI) from aqueous systems by a marine sponge, Sarcotragus foetidus (Schmidt, 1862) has been investigated. S. foetidus samples were collected from Babakale/Ayvacık/Canakkale in Turkey. Uranium (VI) uptake experiments were carried out by the batch technique. The affecting parameters were analyzed using Central Composite Design (CCD) as the experimental method. Four independent variables such -pH, temperature, contact time, and initial uranium concentration were selected for this study. The influences of initial pH, contact time, and initial uranium concentration on the biosorption process were considered statistically significant as main effects. On the other hand, interaction effects of pH and contact time, as well as pH and initial uranium concentration, were considered as significant parameters on the biosorption process. The optimum condition of biosorption process was found to be at init"ial pH: 4, temperature: 35°C, initial uranium concentration: 20 mg/L, and contact time: 31 minutes. At these conditions, the biosorption yield of uranium (VI) ions was obtained to be 93.29±2%.Keywords: Marine sponge, Statistical design, Experimental Design, Analysis of variance (ANOVA), biological sorption. Sarcotragus foetidus (Schmidt, 1862) Denizel Süngeri ile Uranyum (VI) Biyosorpsiyonunun Merkezi Kompozit Dizayn ile İstatistiksel Olarak Araştırılması ÖzetMikroorganizmalar ve biyolojik materyaller kullanarak radyonüklitlerin, ağır metallerin, toryum ve uranyum gibi radyoaktif metallerin sulu çözeltilerden geri alınması veya uzaklaştırılması üzerine birçok çalışma vardır. Bu çalışmada, Sarcotragus foetidus (Schmidt, 1862) olarak adlandırılan deniz süngerinin sulu çözeltilerden uranyum alımı istatistiksel olarak araştırıldı. S. foetidus (Schmidt, 1862) deniz süngeri örnekleri Babakale (Ayvacık / Çanakkale) açıklarından toplandı. Uranyum (VI) geri alım denemeleri kesikli yöntem ile gerçekleştirildi. Biyosorpsiyonu etkileyen parametreler Merkezi Kompozit Deneysel Tasarımı (CCD) kullanılarak analiz edildi. Bu çalışma için; pH, sıcaklık, temas süresi ve uranyum başlangıç konsantrasyonu gibi dört bağımsız değişken seçildi. Ana parametrelerden pH, temas süresi ve uranyum başlangıç konsantrasyonu biyosorpsiyon prosesinde istatistiksel olarak anlamlı olarak kabul edildi. Diğer bir yandan; biyosorpsiyon işlemi üzerinde, pH-temas süresi, pH -uranyum başlangıç konsantrasyonu gibi ikili etkileşimler önemli parametreler olarak belirlendi. Biyosorbsiyon prosesinin optimum koşulları; pH:4, sıcaklık: 38 , uranyum başlangıç konsantrasyonu: 20 mg/L ve temas süresi: 31 dakika olarak hesaplandı. Bu koşullar altında biyosorpsiyon verimi % 93.29±2 olarak elde edildi.

“…Similarly, two other studied strains, CCY 19-6-4 and CCY 20-2-33, sorbed Se primarily into cells (63 -74%) and the fibrillar part of cell wall (2 -22%), whereas exopolymers bound only 12 -32% of the total sorbed amount. It is known that metals as Cd, Ni, and Zn are sorbed predominantly onto the fibrillar part of cell walls and exopolymers, and, in this way, the cells are protected from the introduction of the toxic metals into the cells [32] [33]. Exopolymers and cell surface serve as a crucial protective barrier against penetration of the metal ions into the cells and their subsequent damage [34].…”

Carotenoid-producing yeast species such as Rhodotorula glutinis and Sporobolomyces roseus efficiently accumulated selenium from the growth medium. It was observed that incorporation of selenium into yeast cells during the growth inhibited production of beta-carotenoid and other carotenoid precursors (torularhodin and torulene). The yeasts with high content of the carotenoid pigments and selenium may be used for the preparation of a new type of antioxidant formula that could be directly applied for various human and animal diets. We have demonstrated that such a formula can only be produced by separate processes of the cultivation of red yeasts and a subsequent sorption of selenium into the cells.
