Abstract
Trends in the dynamically developing application of biocatalysis for the synthesis and modification of polymers over the past 5 years are considered, with an emphasis on the production of biodegradable, biocompatible and functional polymeric materials oriented to medical applications. The possibilities of using enzymes not only as catalysts for polymerization but also for the preparation of monomers for polymerization or oligomers for block copolymerization are considered. Special attention is paid to the prospects and existing limitations of biocatalytic production of new synthetic biopolymers based on natural compounds and monomers from biomass, which can lead to a huge variety of functional biomaterials. The existing experience and perspectives for the integration of bio- and chemocatalysis in this area are discussed.

Li JX, Xu J, Ruan JC, Meng HM, Su H, Han XF, Lu M, Li FL, Wang SA. Disrupting a phospholipase A 2 gene increasing lipid accumulation in the oleaginous yeast Yarrowia lipolytica. J Appl Microbiol 2020; 130:100-108. [PMID: 32648664 DOI: 10.1111/jam.14779] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2020] [Revised: 06/26/2020] [Accepted: 07/04/2020] [Indexed: 02/05/2023]
Abstract
AIMS Phospholipase A2 (PLA2 ) is a diverse superfamily that hydrolyzes fatty acyl ester bonds at the sn-2 position of phospholipids. The correlation between phospholipid metabolism and the anabolism of neutral lipids remains unclear in yeasts. This study aims to explore the effects of PLA2 on lipid accumulation in the oleaginous yeast Yarrowia lipolytica. METHODS AND RESULTS This study identified an actively expressed phospholipase A2 gene (PLA2-3, YAIL0_E16060g) in Y. lipolytica by quantitative PCR analysis. The gene PLA2-3 was disrupted in the strain po1gΔKu70 by homologous recombination and in the strain po1g-G3 by a CRISPR-Cas9 system, which caused an increase in stress sensitivity while the cell growth was not altered under fermentative conditions. Lipid production was performed in both flasks and bioreactors. The results showed that the lipid titre and lipid content were improved over 25% and 8-30%, respectively, in PLA2-3 disrupted strains compared to the controls. CONCLUSIONS Disruption of the phospholipase PLA2-3 gene could effectively improve lipid production in Y. lipolytica. SIGNIFICANCE AND IMPACT OF THE STUDY This study presented a strategy on improving the lipid production of oleaginous yeasts and a similar strategy might be used in other oleaginous microbes.
