Sometimes , answering a long - standing trouble is a subject of finding a new view .
Take methane from cattle : For years , people have beentrying to eliminate the gasfrom moo-cow belch in an attempt to restrain the livestock ’s shock on the clime . But they have n’t made a dent . That ’s in part because they were looking at the return from the perspective of a climate scientist , not a sodbuster .
Kathryn Polkoff , conscientious objector - beginner and CEO ofHoofprint Biome , has been thinking about the problem more like a farmer , though .
“ The first time I get wind about this methane problem was beast science 101 , ” Polkoff , who has a PhD in animal skill , told TechCrunch . It was n’t in the context of climate alteration , but of animal health and productiveness .
Polkoff and her cobalt - founder Scott Collins have stumbled upon a fresh manner to qualify a moo-cow ’s microbiome using enzymes , slashing methane while encourage the nutrient available to the cow .
That discovery has clear Hoofprint a $ 15 million Series A round led by SOSV , the startup exclusively state TechCrunch . Other participating investors include AgriZeroNZ , Alexandria Venture Investments , Amazon ’s Climate Pledge Fund , Breakthrough Energy Fellows , Good Growth Capital , Ponderosa Ventures , and Twynam . The new rung will help oneself the troupe trial its enzymes on farms .
“ We ’ve spent thousand of years engender the animal to make them as efficient as potential and to increase the yield , but there have not really been that many effort to change a microbiome , ” she said . “ That ’d be like if you were engineering a car but had never convert the engine — that ’s where all the vigour come from . ”

hoof mark ’s flow linear tweaks the microbiome in a cow ’s rumen and suppresses the growth of microbes that generate methane , a powerful nursery gas that warm the planet 84 meter more than the same amount of carbon dioxide .
Rumen is a “ hodgepodge gathering line , ” enjoin Po Bronson , the SOSV cosmopolitan partner who precede the firm ’s investment in Hoofprint . The stuff cows eat tends to be very toilsome to bear and draw out nutrients from . Over the millennia , kine have develop alongside a complex microbiome in the first stomach that helps check down the eatage , bring out food in the process .
The cow absorbs some of those nutrients , but not all . Another mathematical group of microbes steals some of those nutrients to push their own growth at the expense of the moo-cow ’s , generating methane as a by - ware . “ It ’s a very specific subset of microbes that are making the methane , ” Polkoff say .
hoof-mark ’s enzyme oppress those microbes . The startup will use yeast to make the enzymes , similar to how other industrial enzyme are made , include those used in tall mallow , detergent , and other products .
For Bronson at SOSV , the fact that Hoofprint ’s enzyme are derived from the rumen itself was fundamental . One previous methane - scale down mathematical product , Bovaer , faced awave of disinformationwhen a big food company announced trial in the U.K. in December .
He does n’t think that Hoofprint will confront the same backlash . “ The core group concept is that their merchandise is a natural protein . They cheapen just like any other protein an animal would eat on . They ’re sort of natural to the first stomach . ”
Hoofprint is targeting a 5 % betterment in “ feed efficiency , ” Polkoff said , or how many more pounds a cow can put on for a afford amount of provender .
By ameliorate the efficiency of a cow ’s first stomach , Bronson is confident Hoofprint will be capable to bring home the bacon with farmers where other startups have give out . “ Knocking down methane is table stakes , ” he enunciate . “ To make it a more rich thing is what they will pay for . ”
