Abstract
Phospholipids are distinctive, adaptable molecules that are crucial to numerous biological systems. Additionally, their various architectures and amphiphilic characteristics support their unrivaled crucial functions in scientific and industrial applications. Due to their enormous potential for use in the fields of medicine, food, cosmetics, and health, structured phospholipids, which are modified phospholipids, have garnered increased attention. Traditional extraction methods, however, are pricy, resource-intensive, and low-yielding. The process of enzyme-catalyzed conversion is effective for producing several types of structured phospholipase. However, most frequently employed catalytic procedures involve biphasic systems with organic solvents, which have a relatively large mass transfer resistance and are susceptible to solvent residues and environmental effects due to the hydrophobic nature of phospholipids. Therefore, the adoption of innovative, successful, and environmentally friendly enzyme-catalyzed conversion systems provides a new development route in the field of structured phospholipids processing. Several innovative catalytic reaction systems are discussed in this mini-review, including aqueous-solid system, mixed micelle system, water-in-oil microemulsion system, Pickering emulsion system, novel solvent system, three-liquid-phase system, and supercritical carbon dioxide solvent system. However, there is still a glaring need for a thorough examination of these systems for the enzymatic synthesis of structural phospholipids. In terms of the materials utilized, applicability, benefits and drawbacks, and comparative effectiveness of each system, this research establishes further conditions for the system's selection. To create more effective biocatalytic processes, it is still important to build green biocatalytic processes with improved performance. KEY POINTS: • The latest catalytic systems of phospholipase D are thoroughly summarized. • The various systems are contrasted, and their traits are enumerated. • Different catalytic systems' areas of applicability and limitations are discussed.

Abstract
Phosphatidylserine (PS) has been widely used in the fields of food and medicine, among others, owing to its unique chemical structure and health benefits. However, the phospholipase D (PLD)-mediated enzymatic production of PS remains a challenge due to the low transphosphatidylation activity of PLD. Therefore, in the present study, we designed a maltose-binding protein (MBP) tag and a PLD co-expression method to achieve the expression of soluble PLD in Escherichia coli. A "reconstruct substrate pocket" strategy was then proposed based on the catalytic mechanism and molecular dynamics simulation, expanding the substrate pocket and manipulating the coordination of l-Ser within the active site. The best mutant (SrMBPPLDMu6) exhibited a 2.04-fold higher transphosphatidylation/hydrolysis ratio than the wild-type Furthermore, under optimal conditions, Mu6 produced 58.6 g/L PS with 77.2% conversion, within 12 h on a 3 L scale, which demonstrates the potential of the proposed method for industrial application.

JOURNAL OF ENVIRONMENTAL MANAGEMENT 2021; 290:112627. [PMID: 33991767 DOI: 10.1016/j.jenvman.2021.112627] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 04/10/2021] [Accepted: 04/11/2021] [Indexed: 05/08/2023]
Abstract
Due to increasing anthropogenic activities, especially industry and transport, the fossil fuel demand and consumption have increased proportionally, causing serious environmental issues. This attracted researchers and scientists to develop new alternative energy sources. Therefore, this review covers the biofuel production potential and challenges related to various feedstocks and advances in process technologies. It has been concluded that the biofuels such as biodiesel, ethanol, bio-oil, syngas, Fischer-Tropsch H2, and methane produced from crop plant residues, micro- and macroalgae and other biomass wastes using thermo-bio-chemical processes are an eco-friendly route for an energy source. Biofuels production and their uses in industries and transportation considerably minimize fossil fuel dependence. Literature analysis showed that biofuels generated from energy crops and microalgae could be the most efficient and attractive process. Recent progress in the field of biofuels using genetic engineering has larger perspectives in commercial-scale production. However, its large-scale production is still challenging; hence, to resolve this problem, it is essential to convert biomass in biofuels by developing novel technology to increase biofuel production to fulfil the current and future energy demand.

Two-step modification of silica for efficient adsorption of phosphatidylcholine in water and application in phospholipase D-catalyzed transphosphatidylation. Biotechnol Prog 2019; 36:e2949. [PMID: 31845503 DOI: 10.1002/btpr.2949] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 12/08/2019] [Accepted: 12/10/2019] [Indexed: 11/09/2022]
Abstract
An efficient and green aqueous-solid system was introduced for phospholipase D-mediated transphosphatidylation. γ-(2,3-epoxypropoxy) propytrimethoxysilane was covalently bound to silica and esterified by acetic acid, which acted as an anchor molecule to facilitate the adsorption of phosphatidylcholine (PC) in aqueous solutions. Obtained silica-adsorbed PC was successfully used for transphosphatidylation to produce phosphatidylserine (PS). The PC loading and PS yield reached 98.8 and 98.3%, respectively. A new model was proposed to illustrate the adsorption and enzymatic processes. Moreover, this aqueous-solid system provides a promising way for the continuous production. Four kinds of phospholipids were biosynthesized in the pack-bed reactor. The stability of the aqueous-solid system was excellent, as demonstrated by its use 30 times without any loss of the productivity. The product was eluted by coconut oil and manufactured into microcapsules. Toxic agents were completely avoided in the whole production process.
