Application of vibrational spectroscopies as process analytical techniques for monitoring fermentation and the conversion of lignocellulosic biomass by oleaginous filamentous fungi [PDF]

Microbial Cell Factories
Background Oleaginous filamentous fungi, such as Mucor circinelloides, are capable of accumulating high levels of single cell oil (SCO), making them attractive candidates for the production of biodiesel and other oleochemicals. Lignocellulosic feedstocks

Raman spectroscopy mapping of changes in the organization and relative quantities of cell wall polymers in bast fiber cell walls of flax plants exposed to gravitropic stress

Frontiers in Plant Science, 2022
Flax is an important fiber crop that is subject to lodging. In order to gain more information about the potential role of the bast fiber cell wall in the return to the vertical position, 6-week-old flax plants were subjected to a long-term (6 week ...
