According to the European Commission, the total annual wine production (2013-2020) in European countries reached a volume of 165 million hL. Europe is also the most important wine exporter occupying around 70% of the global market. In parallel, the wine industry produces a large quantity of biowaste that, in the context of a sustainable economy, needs to be valorized. In order to protect the environment, the landfilling of such biowaste has to be avoided due to its acidity and the possible generation of hazardous products by decomposition. On the other hand, vinification residues contain valuable compounds like: oils, polyphenols, tocopherols, and organic elements (carbon and nitrogen) making the valorization of these by-products compulsory. Ecological solutions for the valorization of grape seeds, grape skins, stems, as well as wine lees resulting from grape vinification have to be found. Different solutions for the processing of these biowastes to generate added value products are described and the economic aspects underlined.</p>","PeriodicalId":7198,"journal":{"name":"Advances in biochemical engineering/biotechnology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497683","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The term \"gut microbiota\" refers to a set of many microorganisms [mainly bacteria], which live symbiotically within the human host. The term \"microbiome\" means the collective genomic content of these microorganisms. The number of bacterial cells within the gut microbiota exceeds the host's cells; collectively and their genes quantitatively surpass the host's genes. Immense scientific research into the nature and function of the gut microbiota is unraveling its roles in certain human health activities such as metabolic, physiology, and immune activities and also in pathologic states and diseases. Interestingly, the microbiota, a dynamic ecosystem, inhabits a particular environment such as the human mouth or gut. Human microbiota can evolve and even adapt to the host's unique features such as eating habits, genetic makeup, underlying diseases, and even personalized habits. In the past decade, biologists and bioinformaticians have concentrated their research effort on the potential roles of the gut microbiome in the development of human diseases, particularly immune-mediated diseases and colorectal cancer, and have initiated the assessment of the impact of the gut microbiome on the host genome.

They are responsible for many natural circulations, including the rotation of elements. They return organic carbon for plants' use and dissolve minerals into organic cycles. Microbes contribute to the global gas and water balances. In animal digestion, they partake in the degradation and assimilation of nutrients. Typically, they act as communities where some strains are the most active at a given time point in the prevailing conditions. But they also live in a continuous state of succession, which precludes the maintenance of changeable balances. Whether functioning in soil, in our alimentary tract, or elsewhere, the micro-organisms decisively contribute to the restoration of various balances. As the microbiological scale differs significantly from our comprehension, we must nurture our understanding of the microbiome wherever it occurs. For example, one spoonful of yoghurt contains approximately as many bacterial cells as there are humans residing on Earth. Therefore, flexibility and interaction are the most advisable modes of operation in microbial biochemistry and biotechnological applications. As microbes tend to form communities, this modus operandi is worth instigating in our process industries and production technologies. The use of microbial mixed cultures most appropriately corresponds to the natural systems [1]. As biocatalysts in human endeavours of biorefining and bioengineering, they have become the most utilizable and producible kind of microbial components. Cooperation with microbes is a prerequisite for the continuous development of sustainable industries and food and health production. The microbial communities can be used to prevent and clean up pollution. In the process design, the microbiological dynamic balances make the highest productivity, repeatability, controllability, and withstanding of entropy. Although their effects have been familiar to our societies, e.g. in the fermentation of foods, their total capacity remains to be put into service.

Hence, mixed cultures are being valorized currently and has also augmented our understanding of microbial activities in communities. This chapter covers a wide range of discussion on recent improvements in mixed culture cultivation for microbial bioprocessing and multifarious applications in different areas. The history of microbial culture, microbial metabolism in mixed culture, biosynthetic pathway studies, isolation and identification of strains, along with the types of microbial interactions involved during their production and propagation, are meticulously detailed in the current chapter. Besides, parameters for evaluating mixed culture performance, large-scale production, and challenges associated with it are also discussed vividly.

The phenomena behind these fluctuations provide microbial cultures with beneficial interphase on the borderlines. Correspondingly, a bioreactor broth usually consists of a liquid phase but also contains solid particles, gas bubbles, technical surfaces, and other niches, both on a visible scale and microscopically. The diffusion limitation in the suspension is a remarkable hindrance to the reaction sequence during production. It must be overcome technically. Gas flow into the reactor could serve this purpose, and the outgoing stream or bubbling contains volatile products. The various mixing elements or gas flows should be moderated if shear forces disturb the cell growth, biochemical production, enzymatic activity, or any other crucial biological or physicochemical parameters. The focus is to optimize energy production in the form of liberated gases or their mixtures. Many combustible flows need to get purified, depending on their purpose, for example, for various engines. They provide novel sources for traffic in the air, streets, roads, and waterways, not forgetting space technology dimensions.On the other hand, industrial fuels are often used as mixtures of gases or gases with other substances. This approach may facilitate the utilization of side streams. Also, municipal energy needs can be fulfilled by microbial gases. Microbial mixed cultures could play an essential role in the big picture of sustainable industries, living of people and agriculture, exhibiting an excessive total effect on societies' multifactorial development. The gas phase is key to realizing their potential.Gaseous emissions are inherent part of all forms of microbial metabolism, both aerobic and anoxic ones. Carbon dioxide is liberated both in respiration and fermentation, but the microbiota also binds volatile carbon compounds. CO&lt;sub&gt;2&lt;/sub&gt; is also a raw material for plant cultivation, e.g., in greenhouses or in algal pools which both often represent the first steps of food chains. Additionally, they produce biomass to produce energy, biochemicals, nutrition, and soil improvement. Gaseous products of the mixed microbial cultures are valuable sources for energy production as purified gases (e.g., biomethane, biohydrogen) or as mixtures (e.g., bio-hythane, volatiles). These relatively simple molecules also serve as supplies for other hydrocarbons (e.g., methanol). Also, many microbial metabolites serve as fuel sources (e.g., bio-oil) and substrates for further biosynthesis. This versatility of potential technological options in energy-making and for industrial processes could offer huge opportunities for green energies and sustainable industries, transportation, or municipalities.
