Craft beer is often produced as a non-filtered, unpasteurized and bottle re-fermented beer, whose production is aimed at maintaining original sensory characteristics. The intention of most micro-breweries is to meet these requirements in producing a high-quality beer. In Italy, as well as in Sardinia, the number of micro-breweries is increasing. In an attempt to make this product more original, new strains of Saccharomyces cerevisiae were selected. Sourdough yeasts were used as an alternative source of starters for beer production. In this particular work, two wheat beers were compared, one brewed with an autochthonous yeast isolated from sourdough and the other brewed with a commercial yeast normally used in Italian micro-breweries. The wheat beer fermented with the autochthonous yeast had the highest ethanol content, the lowest pH and the highest content of esters and alcohols. From a sensory point of view the two beers showed significant differences in the triangle test, but were not significantly different in the paired test with preference.

“…Yeast is a unicellular fungus that can live in both aerobic and anaerobic environments, belonging to the facultative anaerobe type. [29,103] The yeast cells commonly show the sphere-, oval-, ellipse-, or rod-shaped morphologies with the average diameter of 2-6 µm and the length of 5-30 µm. The cell structure is composed of cell wall, cell membrane, nucleus, cytoplasm, vacuole, mitochondria, and some microbodies.…”

“…[18] Microorganisms are mainly divided to three kinds: bacterium, fungus, and virus. [29] Among them, bacteria (e.g., Shewanella oneidensis MR-1 [30,31] and Escherichia coli, [32][33][34] ) and fungi (e.g., Aspergillus niger [35][36][37] and Saccharomyces cerevisiae [20,21,38] ) have attracted tremendous attentions due to their easy reproduction and excellent physicochemical characteristics. On one hand, bacteria and fungi can be utilized as the precursors and doping resources to synthesize in situ single-/dual-/ternary-/quandary-doped carbon materials after the decomposition and pyrolysis of the proteins, phospholipid, and metal salts.…”

Since rapidly increasing energy demands have aroused tremendous research activities on energy storage and conversion, microorganisms (e.g., bacteria, fungi, and viruses) have played significant roles in developing high‐performance electrodes due to their strong abilities of fast reproduction, biomineralization, gene modification, and self‐assembly. Recently, a large quantity of bacteria and fungi has been utilized as the precursors to produce heteroatom–doped carbons or as the biofactories and templates to biomineralize the metal ions to form carbon‐based composites. In addition, in virtue of easy genetic modification, nanoscale viruses with functional groups are directly used as biotemplates for the self‐assembly of the active materials. In this review, a detailed introduction on the microorganisms and their unique abilities as well as the mechanisms behind their operations are discussed. Moreover, recent progress on bacteria‐ and fungi‐derived carbon materials and their composites, as well as the virus‐templated bio‐materials as the electrodes in electrochemical fields, including batteries and electrocatalysts, are further summarized. Finally, challenges and perspectives on the development of the microorganism derivations in electrochemical fields are also provided. This review offers guidance for the rational design of advanced electrode materials from microorganisms and extend the energy systems from the man‐made to biofabrication.

Bioresource-Functionalized Quantum Dots for Energy Generation and Storage: Recent Advances and Feature Perspective

et al. 2022

View full text Add to dashboard Cite

The exponential increase in global energy demand in daily life prompts us to search for a bioresource for energy production and storage. Therefore, in developing countries with large populations, there is a need for alternative energy resources to compensate for the energy deficit in an environmentally friendly way and to be independent in their energy demands. The objective of this review article is to compile and evaluate the progress in the development of quantum dots (QDs) for energy generation and storage. Therefore, this article discusses the energy scenario by presenting the basic concepts and advances of various solar cells, providing an overview of energy storage systems (supercapacitors and batteries), and highlighting the research progress to date and future opportunities. This exploratory study will examine the systematic and sequential advances in all three generations of solar cells, namely perovskite solar cells, dye-sensitized solar cells, Si cells, and thin-film solar cells. The discussion will focus on the development of novel QDs that are economical, efficient, and stable. In addition, the current status of high-performance devices for each technology will be discussed in detail. Finally, the prospects, opportunities for improvement, and future trends in the development of cost-effective and efficient QDs for solar cells and storage from biological resources will be highlighted.
