“…The efficiency of the UASB technology was evaluated by using various feedstocks such as cheese whey (Carrillo-Reyes et al 2014), palm oil mill effluent (Khemkhao et al 2012) and starch wastewater (Lu et al 2015). Potato juice is the thin liquid by-product formed during the production of potato starch after acid-thermal coagulation of proteins (Fang et al 2011;Bzducha-Wróbel et al 2015). Since this waste contains high amount of 3 biodegradable components it is a suitable feedstock for biogas production.…”

Upflow anaerobic sludge blanket (UASB) reactor is one of the most applied technologies for various high-strength wastewater treatments. The present study analysed the microbial community changes in UASB granules during the transition from mesophilic to thermophilic conditions. Dynamicity of microbial community in granules was analysed using high-throughput sequencing of 16S ribosomal RNA gene amplicons, and the results showed that the temperature strictly determines the diversity of the microbial consortium. It was demonstrated that most of the microbes which were present in the initial mesophilic community were not found in the granules after the transition to thermophilic conditions. More specifically, only members from family Anaerolinaceae managed to tolerate the temperature change and contributed in maintaining the physical integrity of granular structure. On the contrary, new hydrolytic and fermentative bacteria were quickly replacing the old members in the community. A direct result from this abrupt change in the microbial diversity was the accumulation of volatile fatty acids and the concomitant pH drop in the reactor inhibiting the overall anaerobic digestion process. Nevertheless, by maintaining deliberately the pH levels at values higher than 6.5, a methanogen belonging to Methanoculleus genus emerged in the community enhancing the methane production

“…Around 45 % of glucan content was observed in the cell wall of yeast grown in DPJW, while 31 % after culturing in YPD, composed of 20 g/l peptone, 20 g/l glucose, and 10 g/l yeast extract (Bzducha-Wróbel et al 2015). Smiderle et al (2012) studied growing submerged cultures of Pleurotus pulmonarius using four different carbon sources, glucose, galactose, arabinose, and xylose.…”

“…In an attempt to obtain β-(1→3)-glucans or β-(1→3),(1→ 6)-glucans with less interfering and higher yields, some advances have shown that the in vitro synthesis of these polysaccharides (Tomazett et al 2010) as well as modifications of the culture medium Papaspyridi et al 2010;Bzducha-Wróbel et al 2015), the increase of the protein expression β-(1→3)-glucan synthase (GLS) that realizes the synthesis of β-(1→3)-glucan (Reverberi et al 2004), and the genetic manipulation (Chai et al 2013) may be described as alternative methods.…”

Biological activities of medicinal mushrooms have been attributed to β-(1→3),(1→6)-glucans that are present in the cell wall of fungi and some plants. Antitumor, immunomodulatory, antimicrobial, antinociception, antiinflammatory, prebiotic, antioxidant, and antidiabetic are some of different properties already described for β-(1→3),(1→6)-glucans. Immune activation systems, including specific β-glucan receptors like Dectin-1, complement (CR3), and Toll (TLR), have been identified to clarify these biological effects. The β-(1→3)-glucans are synthesized by β-(1→3)-glucan synthase (GLS), an enzyme belonging to the glucosyltransferase group, which has a catalytic unit (FKS) and another regulatory (RHO). The mechanisms for adding β-(1→6) branches to the non-reducing ends of the β-(1→3)-glucan chains are unclear until now. Due to the biological importance of β-(1→3),(1→6)-glucan, it is necessary to understand the biochemical and molecular mechanisms of its synthesis, both to optimize the production of bioactive compounds and to develop antifungal drugs that interrupt this process. Therefore, the aim of this review is to gather information about the potential of β-(1→3),(1→6)-glucans, their methods of isolation, purification, and chemical characterization, as well as how these biomolecules are synthesized by fungi and what studies involving biotechnology or molecular biology have contributed to this subject.

“…Valorisation of this by‐product could be of interest to the potato industry (Koduvayur Habeebullah et al , ; Chaves Morillo et al , ; Priedniece et al , ). Another massive wastes from the potato industry are the flesh remaining (75% of initial product mass) from the starch extraction and the wastewaters (Bzducha‐Wróbel et al , ; Ahmed et al , ). According to a recent market report ‘Potato Starch Market: Global Industry Trends, Share, Size, Growth, Opportunity and Forecast 2019–2024' (https://www.potatopro.com/news/2019/growth-global-potato-starch-market), the global potato starch market reached a volume of 3.7 million tons in 2018 and is expected to grow to 4.4 million tons by 2024.…”

Potato processing industry has a high degree of discarding, which currently has low added value being used primarily for animal feed. However, potato wastes offer a broad range of interesting components such as antioxidants, starch, protein or fibre with potential applications in the food and non-food industries. The recovery of these high valuable fractions using efficient multistage and multiproduct processes could be of great interest. This short review provides a general overview on the integral valorisation of potato wastes, offering an updated vision of the main residual parts generated during potato harvesting and processing, the high valuable obtained components focusing on the bioactive ones and the potential of the emerging extraction techniques over conventional ones. In addition, innovative applications are discussed to highlight the scientific and applied interest of these underutilised and undervalued fractions and to emphasise the integral valorisation of raw materials.
