Protein from renewable resources: mycoprotein production from agricultural residues

Abstract

Globally, one in nine people suffer from undernourishment with evidence that this number is increasing. Additionally, due to the projected 50% increase in global population, the demand in worldwide animal-sourced...

Cell‐cultivated food production and processing: A review

“…An ethanol plant producing 43,000 tons of ethanol per year was estimated to be capable of producing 39,000 tons of fungal biomass per year with a capital cost of $50 million and a payback period of about 4.5 years. Similarly, Upcraft et al (2021) performed technoeconomic and lifecycle assessments (LCA) of producing mycoprotein (F. venenatum) using agricultural lignocellulosic residues (rice straw) as feedstock. Various rice straw residues were treated with food-grade ionic liquids in combination with food-grade cellulase enzymes to produce fermentable sugars that were then fed into the corn mycoprotein production process.…”

“…Filamentous fungi have been utilized in food products, especially as mycoprotein. Upcraft et al (2021) presented the results of an LCA of mycoprotein produced from lignocellulosic residues such as rice straw, corn stover, switchgrass, or miscanthus. The results of the LCA demonstrated significant reductions in global warming potential, terrestrial acidification, freshwater eutrophication, and arable land use compared to traditional beef protein.…”

Challenges of assessing the environmental sustainability of cellular agriculture

“…In addition to the optimization of the actual cell-cultivation processes, the sources of the inputs make a large contribution to the environmental impacts. In particular, the possibilities of utilizing side-streams from agriculture and food processing as nutrient sources for cell-culturing processes can provide environmental benefits 7,19 . Extracting glucose and amino acids directly from side-streams would for increasing the renewable energy production capacity according to the global needs 12 .…”

Bioprocesses with Reduced Ecological Footprint by Marine Debaryomyces hansenii Strain for Potential Applications in Circular Economy

“…We found that the protein content increased to 45%, indicating that medium composition deeply affects the protein content of yeast biomass. By using a rich medium, the protein content of D. hansenii Mo40 was comparable to well established meat alternatives such as Quorn by Fusarium venenatum [38] and oncom by Neurospora intermedia [39]. In order to evaluate the ability to produce SCO, D. hansenii Mo40 cells were cultured on lipidogenic medium characterized by low nitrogen content, known to induce lipids accumulation [27].…”
