Scientists engineer bacteria to make two valuable products from plant fiber
We often look to the smallest lifeforms for help solving the biggest problems: Microbes help make foods and beverages, cure diseases, treat waste and even clean up pollution. Yeast and bacteria can also convert plant sugars into biofuels and chemical.....»»
Shipwrecks teem with underwater life, from microbes to sharks
Humans have sailed the world's oceans for thousands of years, but they haven't all reached port. Researchers estimate that there are some three million shipwrecks worldwide, resting in shallow rivers and bays, coastal waters and the deep ocean. Many.....»»
Genetics of host plants determine what microorganisms they attract, finds study
Plants often develop communities with microorganisms in their roots, which influences plant health and development. Although the recruitment of these microbes is dictated by several factors, it is unclear whether the genetic variation in the host pla.....»»
