Designing a Better Probiotic. CRISPR Hubris?

Every morning I pop a Pearl probiotic. I try hard not to drop it, for the tiny, slippery yellow sphere bounces, is impossible to pick up, and cats love to bat them into unreachable domains.


A probiotic is, technically speaking, a population of live microorganisms that confers health benefits on the multicellular organism that they inhabit – such as a human. Probiotics alter the bacterial, viral, and fungal milieu within and on us – our microbiomes – in ways that ease digestion, counter inflammation, strengthen the gut lining, affect brain function, and even squelch tumors.


Each Pearl – or other variation on the probiotic theme – delivers billions of Lactobacilli to the twists and turns, nooks and crannies, of the human host's intestines, maintaining the microbial community within and keeping digestion flowing along smoothly. Other commonly used probiotics are Bifidobacterium and the yeasts Saccharomyces cerevisiae and boulardii.
