yeast

Because of these challenges, microbial proteins found in yeast and fungi have gained attention as promising alternatives to meat.

However, some of the lab's scientists are seeking an alternative by creating the RNAs in yeast, which has the potential to slash costs by 10 to 50 times.

Using this same yeast species, first isolated in France in 1950, the researchers also plan to produce an endothelial growth factor called CdtVEGF.

The thick, brown condiment - made primarily from yeast extract - was invented in the Victorian capital of Melbourne more than a century ago as an alternative to the British spread Marmite.

Then back to the grocery for fresh yeast and the good Italian cheese, and finally, at last, to the kitchen.
