Abstract
GABA (Gamma-aminobutyric acid), a crucial neurotransmitter in the central nervous system, has gained significant attention in recent years due to its extensive benefits for human health. The review focused on recent advances in the biosynthesis and production of GABA. To begin with, the investigation evaluates GABA-producing strains and metabolic pathways, focusing on microbial sources such as Lactic Acid Bacteria, Escherichia coli, and Corynebacterium glutamicum. The metabolic pathways of GABA are elaborated upon, including the GABA shunt and critical enzymes involved in its synthesis. Next, strategies to enhance microbial GABA production are discussed, including optimization of fermentation factors, different fermentation methods such as co-culture strategy and two-step fermentation, and modification of the GABA metabolic pathway. The review also explores methods for determining glutamate (Glu) and GABA levels, emphasizing the importance of accurate quantification. Furthermore, a comprehensive market analysis and prospects are provided, highlighting current trends, potential applications, and challenges in the GABA industry. Overall, this review serves as a valuable resource for researchers and industrialists working on GABA advancements, focusing on its efficient synthesis processes and various applications, and providing novel ideas and approaches to improve GABA yield and quality.
期刊介绍：
Bioresources and Bioprocessing (BIOB) is a peer-reviewed open access journal published under the brand SpringerOpen. BIOB aims at providing an international academic platform for exchanging views on and promoting research to support bioresource development, processing and utilization in a sustainable manner. As an application-oriented research journal, BIOB covers not only the application and management of bioresource technology but also the design and development of bioprocesses that will lead to new and sustainable production processes. BIOB publishes original and review articles on most topics relating to bioresource and bioprocess engineering, including: -Biochemical and microbiological engineering -Biocatalysis and biotransformation -Biosynthesis and metabolic engineering -Bioprocess and biosystems engineering -Bioenergy and biorefinery -Cell culture and biomedical engineering -Food, agricultural and marine biotechnology -Bioseparation and biopurification engineering -Bioremediation and environmental biotechnology
