Apocalypse cow pdf torrent5/18/2023 First, the edible microbial biomass (EMB) is produced under controlled conditions (as in a factory) and so is independent of weather or climate changes. The advantages of producing food using the hydrogen-powered autotrophic route favoured by Solar Foods, as opposed to conventional agricultural production of plant-based protein like soybeans, are legion. As Tom Linder puts it: Large-scale CO2-fixation independent of photosynthesis would seem like an obvious next technology leap in global food production. This cellular machinery allows the microbe to grow biomass without light in an alternative to the more familiar photosynthesizing bacteria, with an energy conversion efficiency 10 times that of photosynthesis. The bacterium has developed no fewer than four enzymes adapted for this task – known as hydrogenases. necator is described as a hydrogen-oxidizing bacterium (also known in German as a knallgas bacterium). The Finnish work has brought out this aspect of the microbe’s functioning. via producing isobutanol) or other organic materials – but very little on it as a source of edible protein. If you look up Cupriavidus in the literature you will find papers discussing it as a source for bioplastics or biofuels (e.g. It is an autotroph – meaning that it can grow without needing any food source other than hydrogen for energy and carbon for building biomass, along with access to key elements such as P, S and N. Neither this paper nor the article accompanying the broadcast of Apocalypse Cow by Monbiot in The Guardian pay much attention to the selection of the autotrophic bacterium Cupriavidus necator, so let me spell out the favourable features of this microbe. And as the Solein producing industry is scaled up, so it will be extracting more and more carbon dioxide from the air – as a counter to carbon dioxide accumulation and its global warming impact by all other agriculture-based food production systems. The Finnish company uses the Direct Air Capture (DAC) technique for sequestering carbon, sourced from its energy partner firm Fortum. What drives the whole process is uptake of carbon, extracted from the air as carbon dioxide. The electricity is 100% from renewable sources in the case of Finland it is supplied by the energy giant Fortum, which operates its own solar and wind farms (as well as coal plants and nuclear plants). The electrolysis to produce the hydrogen is conducted in the growth vessel (vat) rather than externally, so that the designation “electric food” (a term used formerly by Monbiot) is quite accurate. The organism is not toxic to humans, and contains all the essential amino acids, fats and carbohydrates needed for our survival. The chosen bacterium is autotrophic (it can literally “feed itself”) so that it does not require a plant- or animal-based growth medium. Solar Foods has made a number of smart choices in putting together this package. The flour has neutral taste – which is deliberate, so that the Solein can be used as an additive that will not impart its own flavour to foods. The autotrophs capture these ingredients and grow to produce large quantities of biomass, which is continually extracted from the growing vessel, dried, and packaged as something that looks like a yellow flour. There are also some nutrients such as phosphorus (P), nitrogen (N) and sulphur (S) added. The growth medium is water and air it is made up of water which is electrolysed to produce hydrogen (and which sends oxygen into the air) and carbon dioxide that is concentrated from the air. In its lab-based version, which has actually produced an edible product that the company calls Solein (for “solar protein”), an autotrophic soil bacterium called Cupriavidus necatur is selected for rapid growth in an incubator or vat (as in a brewery). The Finnish start-up Solar Foods, ably presented through its co-founders Pasi Vainikka and Juha-Pekka Pitkanen, has put together a package of biotechnologies that they see as having a huge future as they are scaled up.
