Understanding the human body is a team effort. That's where the Yachtel group comes in.

Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years.

Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program.

Tobacco plants, of course, are grown to make cigarettes.

But tobacco is also used a lot in scientific research.

And a new study shows tobacco can be genetically engineered to churn out large amounts of a commercially important bacterial enzyme known as cellulase. The enzyme has

many industrial uses, including as an agent in the production of biofuel. And even while their

plant machinery is being co-opted as an enzyme-making factory, the plants suffer no reduction in

yield while grown out in the field compared with unaltered plants. That fact is rather

remarkable because you might suspect that when a plant is expending resources to create large

amounts of cellulase, it would struggle to grow. But that's not the case here. The proof-of-concept

study is in the journal Nature Plants. University of Illinois plant biologist Justin McGrath is a co-lead

author of the study. He says the work could lead to lower costs for producing useful proteins

like enzymes and some vaccines. That's because it can be way cheaper to cultivate tobacco

plants in a field than to grow genetically modified yeast and other microbes indoors in large

fermenters. Here's McGrath. Our estimates from this study are that it would cost between 20 cents and

$1 to produce a gram of the cellulase, whereas current methods, depending on the type of method you're
