FutureFeed has patented red Asparagopsis algae to target this product since its high bromoform content inhibits this product’s biogenesis with at least 80% efficacy. For 10 points each:
[10m] Name this product. Additives like FutureFeed and 3-nitro·oxy·propanol reduce levels of this product by inhibiting the Coenzyme M pathway, blocking enteric fermentation in target animals.
ANSWER: cow methane emissions [accept cattle or dairy or livestock in place of “cow”; accept CH4 in place of “methane”; prompt on methane emissions or enteric methane emissions by asking “from what animals?”; prompt on reducing carbon, greenhouse gas, or GHG emissions] (3-nitrooxypropanol is sold under the brand name Bovaer.)
[10h] Cargill’s SilvAir instead siphons enteric hydrogen with this salt, generating ammonia rather than methane. In some fertilizers, a double salt of ammonium and this nitrogenous salt immobilizes phosphorus to mitigate eutrophication.
ANSWER: calcium nitrate [or Ca(NO3)2; accept calcium ammonium nitrate; prompt on calcium or Ca2+; prompt on nitrate or NO3-; prompt on CAN by asking “what component of CAN?”]
[10e] Berkeley’s Innovative Genomics Institute is co-creating a pill that uses this tool to edit the cow microbiome and disfavor methanogens. IGI was founded by a pioneer of this technology, Jennifer Doudna.
ANSWER: CRISPR-Cas9 gene editing [or Clustered Regularly Interspaced Short Palindromic Repeat editing]
