Book Description
Cis,cis-muconic acid receives increasing interest to be produced from renewables. Catabolic microbial pathways can be tailored to accumulate cis,cis-muconic acid from a range of aromatic compounds. A renewable, sustainable and under-valued resource for aromatics is lignin. In this work, using hydrothermal conversion, lignin was depolymerized into hydrolysates with up to 615 mM aromatic monomer content. Catechol-rich hydrolysates were generated for bioconversion with the previously developed cis,cis-muconic acid producers P. putida MA-9 and C. glutamicum MA-2, whereas hydrolysates were guaiacol-rich for Amycolatopsis sp. MA-2. When grown with glucose as a co-substrate, C. glutamicum MA-2 yielded 2.6 g L⁻¹ (100 % yield) cis,cis-muconic acid from catechol. Towards an even more sustainable process, glucose was then replaced by hemicellulose, a non-food renewable. Hemicellulose, a co-constituent of lignin in lignocellulose, was hydrothermally converted into a mixture of C₅ and C₆ sugars. As hemicellulose was mainly converted into xylose (91 % yield), C. glutamicum MA-2 was engineered to utilize this pentose. Fed-batch bioconversion on a catechol-rich Kraft lignin hydrolysate as well as a hemicellulose hydrolysate using C. glutamicum MA-4 yielded 4 g L⁻¹ muconic acids. As the developed process was non-competitive to feed and food, it is a promising starting point for future application in bio-based industrial settings.

Book Description
Separation and purification processes play a critical role in biorefineries and their optimal selection, design and operation to maximise product yields and improve overall process efficiency. Separations and purifications are necessary for upstream processes as well as in maximising and improving product recovery in downstream processes. These processes account for a significant fraction of the total capital and operating costs and also are highly energy intensive. Consequently, a better understanding of separation and purification processes, current and possible alternative and novel advanced methods is essential for achieving the overall techno-economic feasibility and commercial success of sustainable biorefineries. This book presents a comprehensive overview focused specifically on the present state, future challenges and opportunities for separation and purification methods and technologies in biorefineries. Topics covered include: Equilibrium Separations: Distillation, liquid-liquid extraction and supercritical fluid extraction. Affinity-Based Separations: Adsorption, ion exchange, and simulated moving bed technologies. Membrane Based Separations: Microfiltration, ultrafiltration and diafiltration, nanofiltration, membrane pervaporation, and membrane distillation. Solid-liquid Separations: Conventional filtration and solid-liquid extraction. Hybrid/Integrated Reaction-Separation Systems: Membrane bioreactors, extractive fermentation, reactive distillation and reactive absorption. For each of these processes, the fundamental principles and design aspects are presented, followed by a detailed discussion and specific examples of applications in biorefineries. Each chapter also considers the market needs, industrial challenges, future opportunities, and economic importance of the separation and purification methods.
