Abstract

A synchronous microbe fermentation process for producing hendecane 1,11-dicarboxylic acid (DC13) with high output from n-tridecane (nC13) features that after the mutational strain resultant from Candidatropicalis is inoculated to culture medium whose matrix is different normal alkanes containing C11-C18, its main action is to grow thallus within 28 hrs, generating a certain quantity of biatomic acid by controlling pH value under 6.8, then to generate acid while growing a certain amount of thallus in 28-60 hrs by controlling pH value under 7.3, and finally to quickly generate different biatomic acids after 60 hrs by controlling pH value to 7.5-7.8. When the process is used to produce DC13 by fermentation in 2.5 cu.m fermentator, the DC13 content is high up to 205 g/l in 161 hrs, the transform rate is 94% and the purity of DC13 is 96-97%.

Description

Producing undecane-1 by microbe simultaneous fermentation from n-tridecane, 11-dicarboxylic acid method
The present invention relates to the method that the synchronous fermentation n-paraffins of microorganism is produced the long-chain alpha, omega-dibasic acid, n-tridecane (nC especially ferments 13) high yield undecane 1,11-dicarboxylic acid (DC 13) method.
C 10Above long-chain biatomic acid is a synthetic senior spices on the chemical industry, senior nylon engineering plastic, high-grade clothing nylon hot-melt adhesive, high temperature dielectric medium, high grade paint, the important source material of lubricating oil additive and cold-resistant plasticizer etc.Especially tridecanyldicarboxylic acid (DC 13) and 15 carbon dicarboxylic acid (DC 15), they are respectively the important source material of synthetic daily spices astrotone and famous and precious spices muskone.
C 10Above long-chain biatomic acid at occurring in nature Individual existence not, has only a few diprotic acid to split from vegetables oil to be situated between and produces, for example sebacic acid (DC 10) can split to be situated between from castor seeds oil and produce; DC 13Can from rapeseed oil, extracting go out the glycerine eruciate again with the production of ozone oxidation method; DC 15Can split to be situated between from the cranial nerve acid the malania oleifera oil and produce.But they all are subjected to the restriction of farmland and weather, far can not satisfy the demand.So far yet there are not economically viable synthetic route and method on the chemical industry.Microbiologist's applied bioengineering technology is utilized the diprotic acid of the normal paraffin production respective chain length in the microbial fermentation oil, has remedied the deficiency on the chemical industry, has opened up the new source of long-chain biatomic acid.
Before the seventies, the various countries scientist sends out the research that alcohol is produced diprotic acid to microorganism, only be in theoretical research stage, the diprotic acid that produces and accumulate also all is the following short chain diprotic acid of ten carbon, after the seventies, enter the applied research stage, by a large amount of induction mutation of bacterium screenings, cultivate a collection of new mutant bacterial strain, can be from ten long-chain biatomic acids that the normal alkane generation more than the carbon is identical with the matrix chain length with accumulation, and, make accumulation several grams from the outset of diprotic acid in every liter of fermented liquid by constantly cultivating and metabolic regulation is studied, tens grams, tens grams are brought up to about present more than 100 grams and two hectograms.
Since the eighties, the research of diprotic acid enters the Small Scale Industry production phase, and several patent documentations that have actual production to be worth occurred.Chinese patent 87105445.0, CN1046757A, CN1092108A and CN1130685A propose to produce the method for long-chain alpha, omega-dibasic acid respectively, particularly distinguish high yield DC 16, DC 17, DC 15And DC 12Method.In 16 liters of automatic controlling tank, fermented DC 5 days 16Be 123g/L, fermented DC 6 days 17Be 133g/L, at 2.5m 3In the general form fermentor tank, fermented DC 6 days 15Be 178g/L, at 3m 3In the fermentor tank, send out alcohol 5 days, DC 12Be 145g/L.
To DC 13Research, Nippon Mining Co., Ltd.'s industry that takes the lead in is amplified, and builds up in 1984 to produce 200 tons DC per year 13The industrial fermentation device, and put into production.Chinese patent CN1071951A proposes a kind of method of asynchronous microbiological fermentative production long-chain alpha, omega-dibasic acid, especially produces DC 13Method.Its method is to carry out in two steps, and according to experimental example 4, the first step is cultured 600 liters of strain liquids to be inserted n-tridecane (nC is housed 13) 3m of 1775 liters of 125 liters and substratum 3In the fermentor tank (being that liquid amount is 83%), PH is 4.5 ± 0.1 in control, and thalline is cultivated in breeding, and 24 hours, cell concentration reached 8.7% (wet bacterium is heavy); Second goes on foot, and adds the nC of 20% (V/V) 13, transfer PH to 7.8 ± 0.1, change the fermentation and acid stage over to, fermented DC 72 hours 13Reach 98.2g/L, continue fermentation 72 hours, produce acid and reach 166.3g/L (beginning to fermentation ends totally 168 hours from inoculation), transformation efficiency is 84%.
The objective of the invention is to propose another kind utilizes the synchronous fermentation n-paraffins of microorganism to produce C 11-C 18The method of long-chain alpha, omega-dibasic acid, especially high yield DC 13Method.
The used bacterial strain of the present invention is candida tropicalis (Candida tropicalis) P-12-242, be to produce the candida tropicalis of mixed dicarboxylic acid (referring to " microorganism journal " 20 (1): 88-93 with a strain oxidation normal alkane, 1980) be starting strain, by nitrous acid and ultraviolet repeatedly repeatedly mutagenesis screening cultivate, can be from C 11-C 18Various single normal alkane and mix normal alkane, especially n-tridecane, the dicarboxylic acid of high production ground production respective chain length.Candida tropicalis P-12-242 (hereinafter to be referred as P-12-242) is deposited in China Committee for Culture Collection of Microorganisms common micro-organisms center, and preserving number is: CGMCC NO..
