Beer spoiling bacteria, oh no! But we know now how you’re made, suckers!

64 - Copy

Over 250 years ago today, on 31 December 1759, Arthur Guinness started brewing one of the most loved adult drinks today, the Guinness beer.

As with all food and drink products, beer can be also suffer spoiling due to various bacteria. The genomes of two of these culprits – Megasphaera cerevisiae PAT 1T and Lactobacillus brevis BSO 464 – have been sequenced in 2015 by two different groups.

Funny thing though: the papers that announce the completion of the genome sequencing (see bellow References) do not talk abut the significance of their discovery. The usual template for a biology paper (or as a matter of fact any science paper) is:

Introduction: x is important because y,
Methods and Results: here is what we did to understand x,
Conclusion: now we can better tackle y.

Not these papers, which basically say, in less than a page: “This bacterium spoils beer; here is its genome. You’re welcome!”

Well played, geneticists, well played… And we are, indeed, grateful. Oh, yes, we are…
