“…All these BC characteristics represent a wide range of potential applications starting from the food industry and biomedicine to electronics and cosmetics. Bacterial cellulose extracted from whey through enzymatic and acidic pre-treatments can be considered as a cheaper growth medium for BC production due to the low-cost of raw materials as well as its enhanced BC yields [ 77 ], reducing environmental pollution from dairy waste. BC has been used as an edible antimicrobial food coating increasing shelf life as well as a healthy food supplement for patients with gastrointestinal disorders, obesity, cardiovascular diseases, and diabetes.…”

There are two types of milk whey obtained from cheese manufacture: sweet and acid. It retains around 55% of the nutrients of the milk. Milk whey is considered as a waste, creating a critical pollution problem, because 9 L of whey are produced from every 10 L of milk. Some treatments such as hydrolysis by chemical, fermentation process, enzymatic action, and green technologies (ultrasound and thermal treatment) are successful in obtaining peptides from protein whey. Milk whey peptides possess excellent functional properties such as antihypertensive, antiviral, anticancer, immunity, and antioxidant, with benefits in the cardiovascular, digestive, endocrine, immune, and nervous system. This review presents an update of the applications of milk whey hydrolysates as a high value-added peptide based on their functional properties.

“…In addition to the products highlighted above, recent efforts in the microbial valorization of whey have included production of pigments (Mehri et al., 2021 ); enzymes such as β-galactosidases (Bentahar et al., 2019 ) and lipases (Knob et al., 2020 ); and polymers such as bacterial exopolysaccharides, bacterial cellulose, and chitosan (Kolesovs & Semjonovs, 2020 ; Kuppamuthu et al., 2020 ; Li et al., 2020 ). Collectively, these results demonstrate that both sweet and acid whey are feedstocks of interest for valorization.…”

The growing burden of waste disposal coupled with natural resource scarcity has renewed interest in the remediation, valorization and/or repurposing of waste. Traditional approaches such as composting, anaerobic digestion, use in fertilizers or animal feed, or incineration for energy production extract very little value out of these waste streams. In contrast, waste valorization into fuels and other biochemicals via microbial fermentation is an area of growing interest. In this review, we discuss microbial valorization of nonconventional, aqueous waste streams such as food processing effluents, wastewater streams, and other industrial wastes. We categorize these waste streams as carbohydrate-rich food wastes, lipid-rich wastes, and other industrial wastes. Recent advances in microbial valorization of these nonconventional waste streams are highlighted, along with a discussion of the specific challenges and opportunities associated with impurities, nitrogen content, toxicity, and low productivity.

“…Dairy whey liquid waste is one of the most polluting by‐products of the food industry. This generated waste is made of 50–55% total milk nutrients that may serve as a potential extra‐nutrient source for strong growth stimulation of KBC during biosynthesis 20,36–38 . Typically, the large‐scale application potential of a trial or fermentation batch is first evaluated following yield and cost‐effectiveness.…”

This work explores the production of kombucha‐derived bacterial cellulose (KBC) from sour whey via the fermentation method using Komagatacibacter xylinus. The biosynthesis process was optimized by design of experiments and the results displayed highest KBC yield at 1000 ml/L sour whey waste, 87.39 g/L cane sugar, 6 g/L black tea, and 78.91 ml/L bacteria volume under 21 days culture period at 30°C. Optimum fermentation batch efficiency was achieved in large scale with cultured medium depths of 0.5 cm and low‐residual bacteria suspension volume of 72.31 ± 8.74 ml. The obtained KBC membranes were analyzed by SEM, FTIR, XRD, and TGA. The obtained results show no significant differences for all prepared KBC samples when compared to pristine bacterial cellulose from standard Hestrin and Schramm (HS) medium. In addition, the optimized KBC was investigated as a suitable bio‐filler in the preparation of biocomposite materials. The prepared biocomposites as leather alternative were further characterized and their mechanical tensile strength and elongation at break determined in the range of 135.61 ± 9.15 to 154.89 ± 9.09 N/mm2 and 31.06 ± 0.32 to 92.33 ± 6.91%, respectively. This model obtained depicts high‐yield production of KBC and its potential in the preparation of biocomposites.
