Example Embodiment

[0027] Example 1: The method for using corn soaking water to produce glutamic acid in a biotin sub-appropriate fermentation process includes the following steps:

[0028] (1) Precipitation: The fresh corn soaking water is deposited in the storage tank for 24 hours;

[0029] (2) Removal of sediment: Open the bottom valve of the storage tank to remove sediment, and judge the amount of discharged material through the sight cup in front of the bottom valve. When the sight cup has no floc, the discharge is complete;

[0030] (3) Delivery: Pump the corn soaking water from the precipitation to the storage tank of the fermentation ingredients station for standby;

[0031] (4) Ingredients: According to the ratio, weigh various raw materials and dissolve them to form a fermentation medium;

[0032] The raw material ratio of the fermentation medium is as follows: starch hydrolyzed sugar: 130g / L; corn soaking water: 100ml / L; sugarcane molasses: 1.5g / L; disodium hydrogen phosphate: 1.6g / L; potassium...

Abstract

The invention discloses a method for producing glutamic acid from corn immersing water in a biotin-suboptimal fermentation process. The innovation of the method is that: a fermentation culture medium is prepared from the corn immersing water instead of corn steep liquor in the biotin-suboptimal fermentation process, so that the glutamic acid is produced by fermenting. The process is convenient tooperate and water-saving and energy-saving, is favorable for reducing the fermenting cost of the glutamic acid and is suitable to be popularized comprehensively in the production. By the method, primary water for batching can be saved, the energy consumed by the further evaporation concentration of the corn immersing water also can be saved, the problems of environmental pollution and energy consumption which are caused by producing the corn steep liquor (powder) by utilizing the corn immersing water are solved, and the acid-producing rate and saccharic acid conversion rate of the glutamic acid are improved simultaneously.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for producing glutamic acid by using corn soaking water instead of corn steep liquor in a biotin sub-quantity fermentation process. Background technique [0002] A large amount of soaking water will be produced in the production process of corn starch, its dry matter content accounts for about 7% to 9%, and its pH value is 3.9 to 4.1. The main components of bioavailability are glucose, various amino acids and trace elements. Biotin, riboflavin, vitamin B1, etc. necessary for life activities. The traditional method of using corn soaking water is to further evaporate and concentrate to produce corn steep liquor or spray it to produce corn steep liquor powder after concentration, which not only consumes a lot of energy, but also pollutes the environment. [0003] Corn steep liquor is an important raw material for glutamic acid biotin sub-quantity fermentation proce...
