“…Another recently used method is biochar immobilization. Biochar constitutes a carbon‐rich material produced via pyrolysis of biomass (Kyriakou et al ., 2020) 51 . Some of the feedstocks used in biochar production are cork, peanut shells, pistachio shells, seagrass residue, vineyard prunings, and non‐biological materials (from recycled car tires) (Table 3).…”

“…Because of the abundance, low price, and rather good purity of natural materials, their use is advantageous for immobilization methodologies 48,50 . Other advantages of natural materials is that they exert low impact on the environment, allow for efficient fermentation processes, 52 and increased yeast resistance to environmental stress 51 . Some examples of natural carriers investigated for the production of 2G bioethanol are sugarcane bagasse and cashew apple bagasse, which were already mentioned in previous sections (Tables 2 and 4).…”

“…Despite their composition, organic supports are either synthetically made (e.g., plastic materials) or obtained from natural sources by complicated techniques (e.g., polymeric hydrogels). The carbonaceous composition of some organic supports affects nutrient availability and product release, and that influences the metabolic behavior of immobilized cells and, consequently, alcoholic fermentation 51 . Examples of organic carriers are biochar, cellulose, chitosan, and polymeric hydrogels like alginate (Tables 2–4).…”

Yeast immobilization with low‐cost carrier materials is a suitable strategy to optimize the fermentation of lignocellulosic hydrolysates for the production of second‐generation (2G) ethanol. It is defined as the physical confinement of intact cells to a certain region of space (the carrier) with the preservation of their biological activity. This technological approach facilitates promising strategies for second‐generation bioethanol production due to the enhancement of the fermentation performance that is expected to be achieved. Using immobilized cells, the resistance to inhibitors contained in the hydrolysates and the co‐utilization of sugars are improved, along with facilitating separation operations and the reuse of yeast in new production cycles. Until now, the most common immobilization technology used calcium alginate as a yeast carrier but other supports such as biochar or multispecies biofilm membranes have emerged as interesting alternatives. This review compiles updated information about cell carriers and yeast‐cell requirements for immobilization, and the benefits and drawbacks of different immobilization systems for second‐generation bioethanol production are investigated and compared.

“…This suggests the importance of finding natural structural materials as supports for cell immobilization, as they offer better mechanical strength and open spaces inside the matrix for cell growth (Iqbal and Saeed, 2005). Several natural supports have been used to immobilize cells for fermentation purpose, such as corn cobs (Genisheva et al, 2011), biochar (Kyriakou et al, 2020) for ethanol production, and grapefruit peel for beer fermentation (Estela-Escalante et al, 2020).…”

Highlight Research AbstractChitin is a natural compound found abundantly in shrimp shells. Chitin can be degraded to produce N-acetylglucosamine, which has wide applications in the food and pharmaceutical fields. Fermentation using chitinolytic microorganisms can be used to produce N-acetylglucosamine from shrimp shells’ chitin. One of the strong chitinolytic bacteria that was isolated from previous research was Providencia stuartii. To provide better stability and efficiency in fermentation, P. stuartii cells were immobilized using entrapment method in papaya trunk wood. The aims of this research were to determine the optimum papaya trunk wood size, ratio of papaya trunk wood and growth medium, as well as the optimum fermentation cycle to produce N-acetylglucosamine from P. vannamei shrimp shells using submerged fermentation method. The research used experimental method with treatment of different sizes of papaya trunk wood (1 x 1 x 1 cm3, 1.5 x 1.5 x 1.5 cm3, and 2 x 2 x 2 cm3), different ratio of papaya trunk wood and growth medium (1:10, 1:15 and 1:20), and 4 fermentation cycles. Results showed that papaya trunk wood with size of 1 x 1 x 1 cm3 and ratio (w/v) of 1:10 could immobilize 87.08±2.05% of P. stuartii cells and produce the highest N-acetylglucosamine concentration, which was 238177.78±3153.48 ppm. The highest N-acetylglucosamine production was obtained from first fermentation cycle and decreased over the last three cycles, but still produced high concentration of N-acetylglucosamine. Therefore, it is possible to perform continuous N-acetylglucosamine production from shrimp shells using P. stuartii cells immobilized in papaya trunk wood.

In a world where fossil fuels are running out, biofuels are one of the best green energy alternatives to fuels made from petroleum due to their environmentally beneficial qualities and low cost in comparison with non-renewable fossil fuels. Biofuels are produced from cheap and renewable sources and the energy stored in these biomasses can be assimilated to create sustainable electricity or heat, which can then be exploited to meet current and future societal needs in numerous situations. However, the production of biofuels on an industrial scale takes a lot of time because of the numerous constraints placed on currently available technology and the increased costs that go along with them. Moreover, the processes utilized to transform various feedstocks into the desired output also vary based on the materials and techniques employed. The supply of biofuel feedstocks is large, and with improved processing, we could significantly lower our reliance on fossil fuels. In this context, the use of nanoparticles (NPs) is a commendable solution to the present problems with biomass use, especially given their low cost. The unique qualities of nanomaterials, such as excellent catalytic properties, high surface area-to-volume ratio, remarkable selectivity, and reusability make them admirable tools for boosting biofuel generation. This review predominantly focuses on the contributions of nanotechnology and various immobilization methodologies in accelerating biofuel production from biomasses that might fill in the research gap, which was previously limited by the relatively lower efficiency of traditional techniques of biofuel generation.
