“…However, such microorganisms are distinguished by a spontaneous decline in cellulose-synthesizing capability and by an appreciable decrease in productivity in the manufacturing environment [18,19]. Therefore, a number of scientific teams put forward a concept of using microbial consortia whose adaptivity is enhanced by synergistic effects in the total metabolism [1], which is especially crucial for alternative nutrient broths prepared from residues of existing food, textile and hydrolytic industries, or prepared from worthless cellulosic raw materials [20]. The peculiar feature of the present study is that a Medusomyces gisevii symbiont was employed, also known as kombucha (tea fungus) [21].…”

Bacterial nanocellulose (BNC) whose biosynthesis fully conforms to green chemistry principles arouses much interest of specialists in technical chemistry and materials science because of its specific properties, such as nanostructure, purity, thermal stability, reactivity, high crystallinity, etc. The functionalization of the BNC surface remains a priority research area of polymers. The present study was aimed at scaled production of an enlarged BNC sample and at synthesizing cellulose nitrate (CN) therefrom. Cyclic biosynthesis of BNC was run in a semisynthetic glucose medium of 10−72 L in volume by using the Medusomyces gisevii Sa-12 symbiont. The most representative BNC sample weighing 6800 g and having an α-cellulose content of 99% and a polymerization degree of 4000 was nitrated. The nitration of freeze-dried BNC was performed with sulfuric-nitric mixed acid. BNC was examined by scanning electron microscopy (SEM) and infrared spectroscopy (IR), and CN was explored to a fuller extent by SEM, IR, thermogravimetric analysis/differential scanning analysis (TGA/DTA) and 13C nuclear magnetic resonance (NMR) spectroscopy. The three-cycle biosynthesis of BNC with an increasing volume of the nutrient medium from 10 to 72 L was successfully scaled up in nonsterile conditions to afford 9432 g of BNC gel-films. CNs with a nitrogen content of 10.96% and a viscosity of 916 cP were synthesized. It was found by the SEM technique that the CN preserved the 3D reticulate structure of initial BNC fibers a marginal thickening of the nanofibers themselves. Different analytical techniques reliably proved the resultant nitration product to be CN. When dissolved in acetone, the CN was found to form a clear high-viscosity organogel whose further studies will broaden application fields of the modified BNC.

“…Therefore, one of the most important and challenging problems limiting the commercial use of bacterial nanocellulose is finding a cost-effective growth medium. At present, many researchers suggest using alternative natural carbon sources (e.g., fruit juices, wheat straw, molasses, maple syrup, cotton-based waste textiles, and other by-products from industry or agriculture) for both economic and ecological reasons [ 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 ]. For instance, Zhao et al [ 71 ] utilized low-cost wine-processing by-products to produce BNC films.…”

“…On the other hand, according to the data presented at the Plastic Free World Conference, as much as 62% of European consumers are ready to pay more for packaging containing less plastic. At the same time, many studies have focused on production costs lowering by optimization of culture media composition or replacing the conventional medium (Hestrin and Schramm) by cheaper alternatives including biomass by-products of various industries or agriculture [ 69 ]. Similarly, the development of modern molecular and synthetic biology tools provides an opportunity and gives prospects for improving BNC-producing strain through metabolic engineering or heterologous gene expression [ 81 ].…”

Bacterial Nanocellulose—A Biobased Polymer for Active and Intelligent Food Packaging Applications: Recent Advances and Developments

2020

The aim of this review is to provide an overview of recent findings related to bacterial cellulose application in bio-packaging industry. This constantly growing sector fulfils a major role by the maintenance of product safety and quality, protection against environmental impacts that affect the shelf life. Conventional petroleum-based plastic packaging are still rarely recyclable and have a number of harmful environmental effects. Herein, we discuss the most recent studies on potential good alternative to plastic packaging—bacterial nanocellulose (BNC), known as an ecological, safe, biodegradable, and chemically pure biopolymer. The limitations of this bio-based packaging material, including relatively poor mechanical properties or lack of antimicrobial and antioxidant activity, can be successfully overcome by its modification with a wide variety of bioactive and reinforcing compounds. BNC active and intelligent food packaging offer a new and innovative approach to extend the shelf life and maintain, improve, or monitor product quality and safety. Incorporation of different agents BNC matrices allows to obtain e.g., antioxidant-releasing films, moisture absorbers, antimicrobial membranes or pH, freshness and damage indicators, humidity, and other biosensors. However, further development and implementation of this kind of bio-packaging will highly depend on the final performance and cost-effectiveness for the industry and consumers.

“…The agricultural waste is considered for economic significance, it is a potential source for renewable energy due to environmentally friendly nature, low cost, and sustainability. Husain et al provide a summary describing culture media to produce bacterial cellulose using different waste products [125]. The corn stalk hydrolysate was used for bacterial cellulose production; it contains glucose, xylose, mannose, furfural, lignin, and acetic acid and 2.86 g/L of cellulose was obtained.…”

Biobased Materials from Microbial Biomass and Its Derivatives

There is a strong public concern about plastic waste, which promotes the development of new biobased materials. The benefit of using microbial biomass for new developments is that it is a completely renewable source of polymers, which is not limited to climate conditions or may cause deforestation, as biopolymers come from vegetal biomass. The present review is focused on the use of microbial biomass and its derivatives as sources of biopolymers to form new materials. Yeast and fungal biomass are low-cost and abundant sources of biopolymers with high promising properties for the development of biodegradable materials, while milk and water kefir grains, composed by kefiran and dextran, respectively, produce films with very good optical and mechanical properties. The reasons for considering microbial cellulose as an attractive biobased material are the conformational structure and enhanced properties compared to plant cellulose. Kombucha tea, a probiotic fermented sparkling beverage, produces a floating membrane that has been identified as bacterial cellulose as a side stream during this fermentation. The results shown in this review demonstrated the good performance of microbial biomass to form new materials, with enhanced functional properties for different applications.
