Special Issue Information

Dear Colleagues,

The research and development of molecular biological sciences is a very active field of science and technology today. Biotechnology and bioengineering based on this field are attracting attention and investment from scientists all over the world. Challenges that require a joint effort of biochemistry experts and scientists with a multidisciplinary approach will be the core of the discussion in our 1st International Congress on Biotechnology and Bioengineering and V Peruvian Congress of Biotechnology and Bioengineering-2021 (https://v-congreso-peruano-de-biotecnologia-y-bioingenieria-2021.webnode.pe/). The congress together with this Special Issue will provide a platform for interrelation between researchers from the academic field, as well as from industry, in the different topics of Biotechnology and Bioengineering. It will constitute a forum for the exchange of ideas, experiences, and information between biotechnologists and professionals involved in biotechnological aspects. We invite all colleagues that have presented a communication in this conference and all over the world to contribute to this Special Issue focused on the current advances on molecular biology applied to Biotechnology and Bioengineering. This Special Issue on “The First Congress on Biotechnology and Bioengineering and V Peruvian Congress on Biotechnology and Bioengineering 2021” invites articles on but not limited to the following topics:

biochemistry, molecular biology, biophysics, structural biology, cell developmental biology biochip technology, microbial fermentation engineering, algae technology, cell engineering, enzyme engineering, and ecological environment engineering.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Biosorption refers to a physicochemical process where substances are removed from the solution by a biological material (live or dead) via adsorption processes governed by mechanisms such as surface complexation, ion exchange, and precipitation. This study aimed to evaluate the adsorption of Zn2+ in seawater using the microalgal biomass of Tetraselmis marina AC16-MESO “in vivo” and “not alive” at different concentrations of Zn2+ (0, 5, 10, and 20 mg L−1) at 72 h. Analysis was carried out by using the Langmuir isotherms and by evaluating the autofluorescence from microalgae. The maximum adsorption of Zn2+ by the Langmuir model using the Qmax parameter in the living microalgal biomass (Qmax = 0.03051 mg g−1) was more significant than the non-living microalgal biomass of T. marine AC16-MESO (Qmax = 0.02297 mg g−1). Furthermore, a decrease in fluorescence was detected in cells from T. marina AC16-MESO, in the following order: Zn2+ (0 < 20 < 5 < 10) mg L−1. Zn2+ was adsorbed quickly by living cells from T. marine AC16-MESO compared to the non-living microalgal biomass, with a decrease in photosystem II activities from 0 to 20 mg L−1 Zn2+ in living cells.
