“…During fermentation, a membrane is produced at the liquid-air interface of the ferment, which is harvested and washed with sodium hydroxide (3M) for purification, thus eliminating the presence of melanoidins and microorganisms. Finally, the membrane is washed with distilled water and repeatedly drained until neutralized (pH 7) [71,80]. The residual NaOH solution is used to treat the residual bagasse from the leaf, and finally, this effluent is treated for final disposal.…”

“…The polymeric membrane was harvested from the fermentation media every 24 h until day 21; then, the membrane was weighed on an analytical balance. Next, the thickness of the BNC formed in the fermentation media was measured with a vernier caliper at ten different points, and their values were averaged as described in [79][80][81].…”

Bacterial Nanocellulose Derived from Banana Leaf Extract: Yield and Variation Factors

Bananas are one of the most important crops worldwide. However, a large amount of residual lignocellulosic biomass is generated during its production and is currently undervalued. These residues have the potential to be used as feedstock in bio-based processes with a biorefinery approach. This work is based on the valorization of banana leaf and has the following objectives (i) to determine the effect of certain physical and environmental factors on the concentration of glucose present in banana leaf extract (BLE), using a statistical regression model; (ii) to obtain Bacterial Nanocellulose (BNC), using BLE (70% v/v) and kombucha tea as fermentation medium. In addition, the physicochemical properties of BNC were evaluated by X-ray diffraction (XRD), Fourier transform infrared (FTIR), and thermogravimetric analysis (TGA). The results indicate that storage time, location, leaf color, and petiole type are factors related to BLE concentration, which is reduced by approximately 28.82% and 64.32% during storage times of five days. Regarding BNC biosynthesis, the results indicate that the highest yield, 0.031 g/g, was obtained at 21 days. Furthermore, it was determined that the highest production rate was 0.11 gL−1h−1 at 11 days of fermentation. By FTIR, it was determined that the purification step with NaOH (3M) should be carried out for approximately two hours. This research supports the development of a circular bioeconomy around the banana value chain, as it presents a way of bioprocessing residual biomass that can be used to produce bioproducts.

“…The dried peels were ground and immersed in distilled water at 90 °C for 60 min. The supernatant was used as a substrate for BC production by using Komagataeibacter xylinus IITR DKH20, to achieve BC of 11.4 g/l (Khan et al 2021). Extracts from citrus processing waste peels of grapefruit and lemon have also been reported (Andritsou et al 2018).…”

Recent advances in bacterial cellulose: a low-cost effective production media, optimization strategies and applications

et al. 2022

Bacterial cellulose (BC), a promising polysaccharide of microbial origin, is usually produced through synthetic (chemically defined) or natural media comprising of various environmental wastes (with exact composition unknown), through low-cost and readily available means. Various agricultural, industrial, and food processing wastes have been explored for sustainable BC production. Both conventional (using one variable at a time) and statistical approaches have been used for BC optimization, either during the static fermentation to obtain BC membranes (pellicle) or agitated fermentation that yields suspended fibers (pellets). Multiple studies have addressed BC production, however, the strategies applied in utilizing various wastes for BC production have not been fully covered. The present study reviews the nutritional requirements for maximal BC production including different optimization strategies for the cultivation conditions. Furthermore, commonly-used applications of BC, in various fields, including recent developments, and our current understanding have also been summarized.

“…For example, Siwina and Leesing identified a new strain of Rhodotorula mucilaginosa which achieved similar lipid yield and titer in raw and detoxified durian peel hydrolysate, despite the presence of inhibitors 5-HMF and acetic acid (Siwina & Leesing, 2021 ) (Table 1 ). A variety of peel wastes have been explored for biovalorization, including durian (Siwina & Leesing, 2021 ), pomegranate (Rayasam et al., 2020 ; Roukas & Kotzekidou, 2020 ), pineapple (Khan et al., 2021 ; Umesh et al., 2019 ), and watermelon. However, the majority of research has focused on citrus peels from industrial juice and marmalade production, as world production volumes are nearly 100 million tons annually ( USDA Foreign Agricultural Service, n.d. ; Khan et al., 2021 ), and 50–60 wt% of the actual fruit processed typically ends up as waste (peels, pulps, seeds) (Negro et al., 2016 ).…”

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.
