” The replacement of ruminant meat with microbial protein in the future might substantially minimize the greenhouse gas footprint of the food system,” states Humpenöder. “The good news is that individuals do not need to be afraid they can consume only greens in the future. They can continue consuming burgers and the like, its just that those burger patties will be produced in a various method.”
Sustainable hamburgers: changing minced red meat with microbial protein
The team of researchers from Germany and Sweden consisted of microbial protein in a computer simulation model to spot the ecological results in the context of the entire food and agriculture system, rather than previous research studies at the level of single items. Their positive situations run until 2050 and account for future population growth, food demand, dietary patterns along with characteristics in land usage and agriculture. As meat intake will likely continue to increase in the future, increasingly more forests and non-forest natural greenery may be destined extinction for pastures and cropland.
” We found that if we substituted 20 percent of ruminant meat per capita by 2050, yearly deforestation and CO2 emissions from land-use modification would be halved compared to a business-as-usual scenario. The decreased varieties of cattle do not only decrease the pressure on land but likewise reduce methane emissions from the rumen of livestock and laughing gas emissions from fertilizing feed or manure management,” says Humpenöder “So replacing minced red meat with microbial protein would be an excellent start to lower the destructive effects of contemporary beef production.”
Microbial protein can be decoupled from farming production
” There are broadly three groups of meat analogs,” Isabelle Weindl, co-author and also researcher at PIK, explains. Our outcomes reveal that even accounting for the sugar as feedstock, microbial protein requires much less farming land compared to ruminant meat for the very same protein supply.”
Microbial protein is made in particular cultures, much like beer or bread. The microorganisms are surviving on sugar and a stable temperature, and getting out an extremely protein-rich product that can taste like, seem like and be as nutritious as red meat. Based upon the centuries-old method of fermentation, it was developed in the 1980s. The US Food and Drug Administration (FDA) greenlighted a microbial protein meat option (mycoprotein) as safe in 2002.
Green biotechnology requires to be sustained by green energy
” Biotechnology offers a promising tool kit for a variety of land-related challenges from ecosystems preservation through improving food security,” says co-author Alexander Popp, leader of the Land Use Management group at PIK. “Alternatives to animal proteins, consisting of alternatives for dairy items, can enormously benefit animal well-being, save water and prevent pressure from biodiverse and carbon-rich communities.” Nevertheless, there are crucial concerns attached to shifting a growing number of production from livestock to fermentation tanks– most notably the energy supply for the production process.
” A large-scale improvement towards biotech food requires a large-scale decarbonization of electrical power generation so that the environment security capacity can be fully established,” Popp includes. “Yet if we do this correctly, microbial protein can help meat-lovers embrace the change. It can truly make a distinction.”

” The food system is at the root of a 3rd of worldwide greenhouse gas emissions, with ruminant meat production being the single largest source,” says Florian Humpenöder, researcher at PIK and lead author of the research study.” The substitution of ruminant meat with microbial protein in the future could substantially reduce the greenhouse gas footprint of the food system,” states Humpenöder. The group of researchers from Germany and Sweden consisted of microbial protein in a computer system simulation design to identify the environmental results in the context of the whole food and agriculture system, as opposed to previous research studies at the level of single products. Our results reveal that even accounting for the sugar as feedstock, microbial protein requires much less farming land compared to ruminant meat for the exact same protein supply.”
The US Food and Drug Administration (FDA) greenlighted a microbial protein meat alternative (mycoprotein) as safe in 2002.
Replacing 20% of meat from cattle with microbial protein– a meat alternative produced in fermentation tanks– by 2050 could halve deforestation, a brand-new analysis by the Potsdam Institute for Climate Impact Research (PIK) now published in Nature finds.
” The food system is at the root of a 3rd of worldwide greenhouse gas emissions, with ruminant meat production being the single largest source,” says Florian Humpenöder, researcher at PIK and lead author of the study. That is because a growing number of forests that store a great deal of carbon are cleared for livestock grazing or growing its feed, and since of additional greenhouse-gas emissions from animal agriculture. Part of the option could be existing biotechnology: Nutritious protein-rich biomass with meat-like texture produced from microbes like fungi by means of fermentation, what researchers call “microbial protein.”
