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
