“…Gluconic acid is commonly used in the food industry; it is soluble in water, nontoxic, and presents good chelation capacity at high pH ( Goldberg and Rokem, 2009 ). Current commercial production occurs with Aspergillus niger under submerged state fermentation ( Yadav and Chauhan, 2022 ). However, the production of this acid was already reported in several bacterial strains such as Pseudomonas and Acetobacter .…”

Polyhydroxyalkanoate (PHA) production using halophilic bacteria has been revisited because less severe operational conditions with respect to sterility can be applied, also alleviating production costs. Halomonas boliviensis was selected because it is a moderate halophile able to grow and attain high poly-3-hydroxybutyrate (P3HB) contents under 5–45 g/L NaCl concentrations, conditions that discourage microbial contamination. Industrial residues of the red alga Gelidium corneum after agar extraction were used as sugar platform to reduce costs associated with the carbon source. These residues still comprise a high carbohydrate content (30–40% w/w) of mainly cellulose, and their hydrolysates can be used as substrates for the bioproduction of value-added products. Preliminary assays using glucose were carried out to determine the best conditions for growth and P3HB production by H. boliviensis in bioreactor fed-batch cultivations. Two strategies were addressed, namely nitrogen or phosphorus limitation, to promote polymer accumulation. Similar P3HB cell contents of 50% (gpolymer/gCDW) and yields YP3HB/glucose of 0.11–0.15 g polymer/g glucose were attained under both conditions. However, higher specific productivities were reached under P-limitation, and thus, this strategy was adopted in the subsequent study. Two organic acids, resulting from glucose metabolism, were identified to be gluconic and 2-oxoglutaric acid. Reducing the oxygen concentration in the cultivation medium to 5% sat was found to minimize organic acid production and enhance the yield of polymer on sugar to 0.20 gP3HB/gglucose. Finally, fed-batch cultivations using G. corneum hydrolysates as the only C-source achieved an overall volumetric productivity of 0.47 g/(L.h), 40% polymer accumulation, and negligible gluconic acid production.

“…Other filamentous fungi, such as Gonatobotrys, Gliocladium, Penicillium and Scopulariopsis were found to produce gluconic acid (Goldberg and Rokem 2009;Dowdells et al 2010). Gluconic acid and its derivatives have various applications in pharmaceuticals, cosmetics, and food products as additive or buffer salts (National Center for Biotechnology Information 2022b; Yadav et al 2022). The market size of gluconic acid was more than USD 50 million in 2017 (Global Market Insights 2022b).…”

Fungi provide ecological and environmental services to humans, as well as health and nutritional benefits, and are vital to numerous industries. Fermented food and beverage products from fungi are circulating in the market, generating billions of USD. However, the highest potential monetary value of fungi is their role in blue carbon trading because of their ability to sequester large amounts of carbon in the soil. There are no conclusive estimates available on the global monetary value of fungi, primarily because there are limited data for extrapolation. This study outlines the contribution of fungi to the global economy and provides a first attempt at quantifying the global monetary value of fungi. Our estimate of USD 54.57 trillion provides a starting point that can be analysed and improved, highlighting the significance of fungi and providing an appreciation of their value. This paper identifies the different economically valuable products and services provided by fungi. By giving a monetary value to all important fungal products, services, and industrial applications underscores their significance in biodiversity and conservation. Furthermore, if the value of fungi is well established, they will be considered in future policies for effective ecosystem management.

A durable electrochemical performance in lithium-ion batteries (LIBs) is increasingly important in future applications. Various strategies were used to develop functional binders for long cycles, high loading, and fast charging. However, despite constant efforts, the strategies mentioned above remain critically challenging and must be addressed. Herein, we utilized a nontoxic, water-soluble, and bioderived polymethylene-based binder containing a high concentration of carboxylic acid functional groups as side chains, demonstrating improved lithium-ion transport and minimizing electrolyte decomposition. Polymethylene’s less flexible rod-like polymer architecture succeeds in exhibiting long cycling at 1 C with a specific capacity of 325 mAh g–1 and capacity retention of 79% at the 710th cycle. It also performed better fast charging behavior at 5 C with a specific capacity of 54 mAh g–1 and showed better rate and long cycling stability with high loading of graphite up to 3.4 mg cm–2. Hence, a poly(fumaric acid) binder enhances the LIB’s electrochemical performance and mechanical strength.
