“…Therefore, thermal stress is relevant in the process, plus the obvious rise in osmolarity due to the efflux of water, and also an internal oxidative insult, has been detected (Pérez‐Torrado et al . ).…”

“…This tolerance to drying has proven biotechnological utility. Spontaneous traditional fermentations are still carried out, but most fermentations on an industrial scale rely on a selected yeast inoculum (P erez-Torrado et al 2015). This makes the process more reliable as yeast with good fermentative and organoleptic behaviour can be selected to perform fermentation.…”

Wine yeast deals with many stress conditions during its biotechnological use. Biomass production and its dehydration produce major oxidative stress, while hyperosmotic shock, ethanol toxicity and starvation are relevant during grape juice fermentation. Most stress response mechanisms described in laboratory strains of Saccharomyces cerevisiae are useful for understanding the molecular machinery devoted to deal with harsh conditions during industrial wine yeast uses. However, the particularities of these strains themselves, and the media and conditions employed, need to be specifically looked at when studying protection mechanisms.

“…Fungus shows great potentials in energy-related fields in the past few decades due to its fast reproduction, large-scale production, and variety. [103] The main component of cell wall is chitin, which is different from the cellulose of the plants. In addition, the fungus contains several fungal organelles including mitochondria, microsomes, ribosomes, vacuoles, lysosomes, vesicles, endoplasmic reticulum, microtubules, and flagella.…”

“…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.…”

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.

“…The main ingredient of industrial production medium used in yeast production factories are beet or cane molasses, mainly because of the low cost of this waste products and high sucrose content. In most cases, the industrial production is a multistage process carried out under batch or fed-batch conditions with sequential stages differing in fermenter size, performed under controlled intense aeration [34]. Aeration is generally considered as the most important single factor to increase yeast yield and numerous studies have been carried out to investigate the optimization of particular technological solutions [35].…”

Yeast - Industrial Applications

Yeasts represent a very diverse group of microorganisms, and even strains that are classified as the same species often show a high level of genetic divergence. Yeasts biodiversity is closely related to their applicability. Biotechnological importance of yeast is almost immeasurable. For centuries, people have exploited its enzymatic potential to produce fermented food as bread or alcoholic beverages. Admittedly, yeasts application was initially instinctual, but with science and technology development, these microorganisms got the object of thorough scientific investigations. It must be recognized that yeast represents an excellent scientific model because of its eukaryotic origin and knowledge of genetics of yeast cells as well as metabolism examined in detail. In 1996, the genome of baker yeast Saccharomyces cerevisiae has been elucidated, what opened the opportunity for the global study of the expression and functioning of the eukaryotic genome. Also, currently, an international team is working on the synthesis of the 16 yeast chromosomes by synthetic biology tools, and the results are expected till the end of the year. Nowadays, yeast is regarded as a versatile tool for biotechnological purposes.
