Special Issue Information

Dear Colleagues,

Yeast is regarded as a versatile tool for biotechnological purposes. For thousands of years, yeasts have been exploited by mankind for the production of foods and beverages. Their metabolic versatility, robustness under fermentation conditions, generally recognized as safe (GRAS) status, ease of culture, and the availability of biomolecular tools have made yeasts one of the main workhorses in biotechnology. Recent advances in genomics, metabolic engineering, and synthetic biology have enabled the engineering of yeasts to function as microfactories for the production of relevant compounds such as pharmaceuticals, biofuels, fine chemicals, and proteins. Yeasts also have a great potential in molecular biology as a biomolecular toolbox. Among the various yeast species, Saccharomyces cerevisiae stands out for its high fidelity and high frequency of homologous DNA recombination, which has been successfully exploited in the synthesis of large DNA fragments (as whole genomes) and the engineering of enzymes by directed evolution through so-called in vivo DNA shuffling.

Although S. cerevisiae is the best genetically and biologically characterized yeast and the most widely used in industrial applications, new players are rapidly emerging, such as Pichia pastoris, Hansenula polymorpha, Yarrowia lipolytica, and Kluyveromyces marxianus, to name but a few.

For this Special Issue, “From Yeast to Biotechnology, Volume 2”, we invite authors to submit articles covering all aspects of this theme, including but not limited to yeast engineering for high-value compound production, yeast genome engineering, computational design/modeling/analysis applied to yeast biotechnology, methods to characterize yeast, yeast as a biomolecular toolbox, yeast biosensors, and yeast industrial fermentation processes.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Bioengineering is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Yeast Saccharomyces cerevisiae may be regarded as a cost-effective and environmentally friendly biosorbent for complex effluent treatment. The effect of pH, contact time, temperature, and silver concentration on metal removal from silver-containing synthetic effluents using Saccharomyces cerevisiae was examined. The biosorbent before and after biosorption process was analysed using Fourier-transform infrared spectroscopy, scanning electron microscopy, and neutron activation analysis. Maximum removal of silver ions, which constituted 94–99%, was attained at the pH 3.0, contact time 60 min, and temperature 20 °C. High removal of copper, zinc, and nickel ions (63–100%) was obtained at pH 3.0–6.0. The equilibrium results were described using Langmuir and Freundlich isotherm, while pseudo-first-order and pseudo-second-order models were applied to explain the kinetics of the biosorption. The Langmuir isotherm model and the pseudo-second-order model fitted better experimental data with maximum adsorption capacity in the range of 43.6–108 mg/g. The negative Gibbs energy values pointed at the feasibility and spontaneous character of the biosorption process. The possible mechanisms of metal ions removal were discussed. Saccharomyces cerevisiae have all necessary characteristics to be applied to the development of the technology of silver-containing effluents treatment. Full article
