key components are made of glass.
The researchers demonstrated that micro-optical glass coatings
can increase the efficiency of solar cells.

Microbe Turns Waste into

The method could be applied to carbon

team of researchers has bioengineered a microbe to efficiently
turn waste into itaconic acid, an industrial chemical
used in plastics and paints.
Producing itaconic acid currently involves fungi feeding on
relatively pure sugars, which can be expensive. The team used
lignin, a waste product from biorefineries and paper mills, to
grow the bacterium Pseudomonas putida for potentially cheaper
itaconic production.
The trick was to separate the mi crobes' growth phase from
itaconic production using dynamic controls. The team de -
signed and deployed a biosensor that triggers the metabolic
pathway for itaconic acid production only after the microbes
consume all the nitrogen that fuels their growth.
The technology could provide additional revenue for biorefineries
by turning lignin into a high-value chemical. One
strain achieved nearly 90% of theoretical yield during the production
phase and could be further optimized. These methods
also could be applied to a range of carbon waste streams.
