Solar Foods prepares to commercialise novel protein Solein in Q4 2022
https://www.foodnavigator.com/...lar-Foods-prepares-to-commercialise-novel-protein-Solein-in-Q4-2022

In an interview with FoodNavigator last year, Vainnika likened Solein’s manufacturing process, for the layman, to wine or beer production. To make wine, grapes provide the sugar and carbon for the fermentation process, before yeast is added to convert the sugars into the final alcohol product. Instead of yeast, the CEO explained, Solar Foods uses a ‘completely natural’ proprietary organism . And instead of sugars, this bacteria eats CO ₂ and hydrogen for its source of carbon and energy. For the nitrogen element, Vainnika continued, the company uses ammonia in a water solution. “It is produced from nitrogen in the air already by combining with hydrogen. We can make our own ammonia from the air, as we already produce a lot of hydrogen for the microbes. “We feed the bacteria with the CO₂ and hydrogen bubbles [produced using water electrolysis] and it grows and multiplies.” In the future, the CEO suggested Solar Foods m ay investigate renew able solar or wind energy, rather than hydropower as its electricity source

YMLADRIS: ad synteticky bilkoviny, uz jsem to sem poruznu daval, jde defakto o vetsi domestikaci autotrofnich organismu.



Single-cell protein - Wikipedia
https://en.wikipedia.org/wiki/Single-cell_protein

Single-cell proteins (SCP) or microbial proteins[1] refer to edible unicellular microorganisms. The biomass or protein extract from pure or mixed cultures of algae, yeasts, fungi or bacteria may be used as an ingredient or a substitute for protein-rich foods, and is suitable for human consumption or as animal feeds


Agriculture-independent, sustainable, fail-safe and efficient food production by autotrophic single-cell protein [PeerJ Preprints]
https://peerj.com/preprints/1279/

This hypothesis paper proposes autotrophic SCP bioprocess designs which enable sustainable, fail-safe and efficient production of edible biomass from CO2 and N2 or NH3. They can be driven by H2, CO or HCOOH from several sustainable sources. Besides H2O-electrolysis and syngas, surprisingly fossil fuel may provide an effectively carbon-negative and cheap supply of H2 through the decomposition of CH4 or oil. Most promising bioprocess designs consist of 2-stages. In the first stage, homoacetogenic bacteria fix CO2 up to 10 more efficiently than plants, and secrete it as acetate. In the second stage, selected microbes grow on the acetate and thereby form edible biomass. Bacteria have unique features including N2-fixation, H2S tolerance and O2-tolerant hydrogenases for fast light-independent growth. Eukaryotic microalgae are already approved as food and exhibit oxygenic photosynthesis which partly replaces solar-panels, seawater desalination and H2O-electrolyzers. Photoheterotrophic growth on acetate decouples these benefits from inefficient endogenous CO2 fixation. Slow gas mass-transfer, poor light distribution and expensive cell harvest are major challenges arising from the cultivation in liquid media. To cope with this, microbes grow as hydrated biofilms that are exposed directly to substrate gases, and that can be dry-harvested.

asi se tam naskyta i vylozene nejaka jeste syntetictejsi cesta, neco ala:
- vyroba renewable vyroba vodiku
- v reverznich fuel cells vyroba amoniaku z vody a vzdusnyho dusiku: https://www.sciencemag.org/...renewable-fuel-made-sun-air-and-water-could-power-globe-without-carbon
- amoniak a vodik vyuzivany pro syntezu bilkovin

SHEFIK: a ted doufam, ze prijde nejaka kritika, protoze me samotnymu prijde konverze 0.9kg -> 1kg zvlastni. znamenalo by to, ze cervi nabiraji svoji hmotu z dalsich vstupu, napada me jen vzduch, nebo voda

YMLADRIS: tadeas to trochu zjednodusuje, chce to trochu vetsi detail, nez hmyz odsoudis :)

zakladem je, ze na kazdej vystup, potrebujes vstupy. (energie, material)

zivej organismus/bunka ma nejakou efektivitu konverze vstupu na nami chteny vystup

ta efektivita konverze je ruzna od organismu/odrudy zvirete (a samozrejme i od vstupu - celuloza je jinak stravitelna, nez moucna kase, u lidi napr. cokolada x zelenina)

tzn. nejjefektivnejsi na konverzi (materialove, zanedbavam dalsi vstupy) by dle logiky melo byt laboratorni maso, protoze tam nemas bazalni spotrebu energie a materialu zbytku organismu a zivis jen mnozeni svalove (nebo jine) bunky s cilem rustu. otazkou je energie nutna na pripravu nakyho zivnyho roztoku, energeticka stimulace pohybu svalu, setup podminek atd. chvili bude trvat, nez se tam dostanem

a pak uz odkazu na FCR na wiki - https://en.m.wikipedia.org/wiki/Feed_conversion_ratio

kde si muzes napr. srovnat FCR drubeziho 1.6 (tzn. 1,6 kg krmiva na kg masa) a FCR hmyzu 0.9-1.1

dulezity je, ze FCR se hmyzu teprve vyviji, neni to desetileti osvojeny hospodareni jako napr. u drubeziho. tzn. muze se jeste vyvijet (i kdyz asi uz ani neni moc kam u pomeru 0.9...)

kdyz to prelozim do diskuze tady, tak pokud vypestujem 0.9kg nejaky plodiny, a je jedno, jestli regenerativne, nebo intenzivnim zemedelstvim, jsme schopny skrz krmeni cervu dostat 1kg vysoce kvalitniho bilkovinnyho "vstupu" pro lidi :)

TADEAS: pro lidi od kompu to samozrejme vzdycky bude fantazie, protoze zvednout prdel a jet nekam presvedcovat sam sebe je proste narocny.

hur dur

od kompu je vsechno tak nejak jedno. kdyz ale clovek zabori ruku po loket do pastviny na farme, kde to jedou par dekad, protoze je to ta puda tak kypra, a na tom samym miste na zaboreni lopaty rozpuli 50 zizal, tak je to proste tak nejak zajimavejsi :D

LINKOS:

rozlisil bych v tomhle nekolik veci

(spis pro jiny lidi nez pro tebe, presvedcovat tvrdohlavy jednotlivce nemam zajem, i kdyz u petra pana se to povedlo, taky me se savorym na zacatku poslal do prdele - zkratka patent na rozum muzes mit, jen je potreba si to lip promyslet, wikipedie a sierraclub bhzl nebudou fungovat na prvni dobrou :) ale pokud chces mit tzv pravdu tak prijemnou zabavu :))


1/ jedna vec je holistic management jako metoda managementu ekosystemu, socialniho aspektu, financi, to je fakt docela siroce ocenovany a prijimany v ty farmarsky komunite, tj. lidma od zvirat, stromu, semen ,)

- clanek/studie k tomu, proc je to predmetem takovejch kontroverzi: [ TADEAS @ Klimaticka zmena // anger is a key adaptive emotional driver of engagement with the climate crisis ]


2/ potencial sekvestrace pud a souvislost s managementem traviny-bylozravci

- jeden z pedologu co se tim zabyva a prezentuje je ratan lal, ma dobry videa, da se skrz to jit k nejakejm dalsim studiim [ TADEAS @ Klimaticka zmena // anger is a key adaptive emotional driver of engagement with the climate crisis ]

- organizace soil4climate kolektuje vyzkumy/monitoring farem, ktery talto operujou: [ TADEAS @ Klimaticka zmena // anger is a key adaptive emotional driver of engagement with the climate crisis ]

- francouzska iniciativa https://www.4p1000.org/ lze se podivat na cem to zakladaj


3/ savoryho nazory na potencial sekvestrace a publicistika s tim spojena

- pro me asi nejmin zajimavej aspekt veci, pokud to privede vic lidi k tomu, ze ten potencial tu je, jen dobre :)

Scientists in California just ran the numbers on what would happen if their state slapped solar panels on 4,000 miles of its canals, including the major California Aqueduct, and the results point to a potentially beautiful partnership. Their feasibility study, published in the journal Nature Sustainability, finds that if applied statewide, the panels would save 63 billion gallons of water from evaporating each year. At the same time, solar panels across California’s exposed canals would provide 13 gigawatts of renewable power annually, about half of the new capacity the state needs to meet its decarbonization goals by the year 2030.
