Abstract:
Corynebacterium glutamicum has been mainly used for industrial production of amino acids, and in recent years, it has also been successfully engineered to broaden its range of substrate and product profiles. In particular, C. glutamicum has been engineered to use non-natural sugar substrates (mainly pentoses) derived from hemicellulosic feedstock, which is the second abundant component of lignocellulosic biomass. Engineering of the host in this context can greatly contribute to the development of an economic and sustainable bioprocess. The present review focuses on the recent progress in engineering C. glutamicum towards efficient utilization of pentose sugars derived in hemicellulose and for direct utilization of hemicellulose. In addition, use of C. glutamicum as a biocatalyst for bioconversion of low-value sugars derived from hemicellulose to high-value product has been reviewed.

Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
Types of Advanced Functional Groups
The table below summarizes some of the major functional groups in organic chemistry.

Heat Engines
Whenever we consider heat engines (and associated devices such as refrigerators and heat pumps), we do not use the standard sign convention for heat and work. For convenience, we assume that the symbols Qh, Qc, and W represent only the amounts of heat transferred...
