“…FAO also reports that around 1.3 billion tons of food are wasted annually, accounting for a third of all edible foodstuffs produced worldwide (FAO, 2019). This unsatisfactory state reflects the gap between theory and practice, which is mostly due to the technological and economic unfeasibility of many of the valorization strategies (Mou et al, 2023). But new progressive studies seem to be promising by providing waste management and the production of alternative products as a contribution to the circular economy at the same time.…”

Cellulose is defined as a polymer that exists in the cell walls of plant tissues and is widely used in many industrial fields. However, the recent threat of deforestation has led researchers to find alternative wood sources for cellulose production. For this reason, literature studies have focused on certain types of bacteria known to be capable of producing cellulose, such as Acetobacter, Gluconobacter, Alcaligenes, etc. It is stated that cellulose of plant origin and bacterial origin have a similar structure. Bacterial cellulose possesses a big economic and commercial potential depending on the purpose and the production method and is generally used in food applications as a fat substitute, rheology modifier, immobilization material for probiotics and enzymes, stabilizer of pickering emulsions, component of food coatings and green packaging film. Recently, it has become more prominent to use food waste as production inputs, such as beet and sugar cane molasses, fruit waste, dairy industry waste, etc. So, the utilization of industrial by-products, agro-forestry, and food industry residues as carbon sources has been providing significant advantages, such as increasing yield and reducing cost. The objective of this study was to present a general look related to bacterial cellulose production in combination with the use of food waste and future trends.

The production of bacterial cellulose (BC) has indeed garnered global attention due to its versatile properties and applications. Despite potential benefits, the challenges like low productivity, high fermentation costs, and expensive culture media hinder its industrialization. Utilizing low‐cost substrates, especially waste streams, can help address the challenges. In this study, waste feedstocks such as restaurant leftovers, oranges, and grapefruit from canteens and supermarkets were valorized for BC production by Komagataeibacter sucrofermentans. Orange juice is a fascinating substrate with a highest concentration of 20.6 g/L and productivity of 2.05 g/L/d. Using HS medium with supplementary ions, organic acids, ethanol, and various carbon sources is a strategic approach for enhancing BC production. The study reveals that the addition of organic acids or ethanol moderately increased BC production, while ions inhibit BC synthesis, highlighting the complex interplay between various cultivation medium components. Additionally, fermentation with K. sucrofermentans using single and mixed carbon sources was conducted to elucidate the potential metabolic mechanism of BC production. Through alkaline treatment and drying in a 30 °C incubator, we produced the highest quality BC with 92.09% crystallinity. Overall, the study enhances BC production knowledge and provides green and sustainable strategies for fermentative BC production.

BACKGROUNDGlobal food loss and waste have raised environmental concerns regarding the generation of greenhouse gases (e.g., carbon dioxide and methane gas), which directly contribute to climate change. To address these concerns, the present research aims to upcycle food waste into an alternative culture medium for the cultivation of microalgae. Various parameters including pretreatment of food waste (i.e., autoclave and non‐autoclave), concentration of food waste culture medium (i.e., 10%, 30%, 50%, 70%, 90% and 100%), harvesting efficiency and biochemical compounds of Chlorella sp. microalgae were carried out.RESULTSBased on the preliminary findings, the highest biomass concentration obtained from 10% food waste culture medium in the autoclave for Chlorella sp., including strains FSP‐E, ESP‐31 and CY‐1, were 2.869 ± 0.022, 2.385 ± 0.018 and 0.985 ± 0.0026 g L−1, respectively. Since Chlorella vulgaris FSP‐E exhibited the highest biomass concentration, this microalgal strain was selected to examine the subsequent parameters. Cultivation of C. vulgaris FSP‐E in 100FW achieves a biomass concentration of 4.465 ± 0.008 g L−1 with biochemical compounds of 6.94 ± 1.396, 248.24 ± 0.976 and 406.23 ± 0.593 mg g−1 for lipids, carbohydrates and proteins, respectively.CONCLUSIONThis study shows that using food waste as an alternative culture medium for C. vulgaris FSP‐E can achieve substantial biomass productivity and biochemical content. This research work would contribute to the concept of net zero emission and transitioning toward a circular bioeconomy by upcycling food waste as an alternative culture medium for the cultivation of microalgae. © 2024 Society of Chemical Industry.
