Description

Aureobasidium pullulans strain and application thereof in synthesis of 2, 5-dihydroxymethylfuran
Technical Field
The invention belongs to the technical field of biochemistry, and particularly relates to an aureobasidium pullulans strain and application thereof in catalyzing selective reduction synthesis of 2, 5-dihydroxymethylfuran by 5-hydroxymethylfurfural.
Background
With the deepening of sustainable development concepts of green energy resources for replacing petroleum resources and environmental protection alternatives in the chemical industry, the biomass energy and the biotechnology occupy more and more critical positions in the current generation with increasingly severe resource and environmental problems. 5-Hydroxymethylfurfural (HMF) is considered to be the most valuable and potential bio-based platform chemical to replace the basic chemicals in the petrochemical industry. Is a byproduct of the lignin pretreatment process and is produced by the dehydration of hexoses (mainly glucose). The research on 5-hydroxymethylfurfural is mainly based on two important reasons: on the one hand, HMF in the biologically pretreated hydrolysate inhibits the growth of many microorganisms and has some toxic effects, thereby affecting the yield and efficiency of the subsequent fermentative synthesis of chemicals and fuels. On the other hand, because the HMF molecule is provided with a plurality of high-activity functional groups such as aldehyde group, hydroxymethyl and carbon-carbon double bond, a series of furan aromatic compounds can be generated by catalytic oxidation reduction. When the aldehyde group on the ring is reduced to hydroxyl, 2, 5-furandimethanol (2, 5-bis-hydroxymethyluran, BHMF) which is the reduction product of HMF is obtained. BHMF, as a diol with high added value, is a key bridge compound in organic synthesis, and has wide application in fine chemical synthesis, preparation research of novel functionalized polyether, polyurethane and multi-heterocyclic compounds of medicines. BHMF is also a new fuel oil which is raised in recent years, has high energy density and is equivalent to gasoline; the boiling point is high, the volatility is low, and the loss caused by storage and use is small; the water absorption in the air is stable and is not easy; the production raw material can be biomass such as cellulose and the like, can reduce the dependence on fossil energy and food, reduce the production cost and is beneficial to protecting the environment (Tetrahedron,2008,64(27): 6358-.
The chemical conversion method mainly uses metal catalyst to catalyze selective reduction of HMF, and is prepared by selective Catalytic Transfer Hydrogenation (CTH) under high-pressure hydrogen, for example, Mingwei Ma et al propose a one-step method to prepare catalyst for catalytic transfer hydrogenation reaction, and reduce Cu 2 (OH) 2 CO 3/AlOOH in situ to prepare catalyst nano-Cu/AlOOH, and react at 160 ℃ for 9h, wherein the HMF conversion rate is more than 99%, the BHMF yield also reaches 89.09%, the heterogeneous catalyst has higher catalytic activity and stability due to the stability of zero-valent copper in the catalyst and the stability of catalyst nanoparticles (Molecular Catalysis,2019,467,52-60), Yanfu Ma et al adopt surfactant-assisted coprecipitation/hydrothermal crystallization method to prepare rare earth metal doped 2 of ZrO 2, so that Co is loaded and used as catalyst, the catalyst has high flammability for preparing BHF in water, the BHMF and hydrogen, the BHMF is prepared by using surfactant-assisted coprecipitation method, the hydrothermal method, and the catalyst has high selectivity of hydrogen, high hydrogen-alcohol preparation, high hydrogen-selective catalyst preparation, high hydrogen-hydrocarbon-alcohol preparation, high hydrogen-selective catalyst-donor-stable reaction cost is improved by the prior art, and the high hydrogen-production safety of hydrogen-resistant catalyst (hydrogen-resistant catalyst) and hydrogen-resistant catalyst, and hydrogen-resistant catalyst is also has the problems of high in the processes of catalytic transfer hydrogenation reaction, such as high flammability, high hydrogen-resistant catalyst, high-resistant catalyst (hydrogen-resistant catalyst, high hydrogen-resistant catalyst.
The biological catalyst can be used for converting and generating the BHMF by taking the HMF as a substrate under mild reaction conditions, has high yield and high selectivity, and simultaneously keeps high chemical purity and low by-product. However, since 5-hydroxymethylfurfural has toxic effects on microbial cells, most microbes have low substrate tolerance concentration on HMF and low catalytic conversion rate of HMF. Therefore, the screening of the obtained microorganism which can tolerate high-concentration HMF, has high conversion speed and good selectivity is particularly important for establishing a biological catalysis path for synthesizing BHMF by taking HMF as a raw material.
