Problems solved by technology

[0002] Due to the high content of bamboo non-cell wall substances (starch, reducing sugar, protein, fat, minerals, etc.), it is very easy to mildew during storage, processing and use, which affects its use value.
Due to the limitations of the internal structure of bamboo, the traditional anti-mildew method of bamboo cannot achieve the ideal anti-mildew effect

Embodiment 1

[0030] The specific steps are:

[0031] Step 1: harvest fresh moso bamboo, remove the sundries on the bamboo stem, and cut the moso bamboo into bamboo sections with a standard length of about 2.0 meters according to the specific use;

[0032] Step 2: Process the bamboo segments into bamboo strips on the bamboo breaking machine, and send them to the four-sided planer for rough planing. The rough planed bamboo strips have a specification of 2000mm×25mm×6mm (length×width×thickness), and they are ready for use;

[0033] Step 3: Take 24 grams of potato dextrose medium (PDb) and 20 grams of agar (Agar) into a 2000 ml glass bottle, add 1000 ml of distilled water, stir well, put it into Harvey for sterilization; take it out after 2 hours, Pour into a white plate, cool for 15 minutes, and when the culture solution is solid, cover it and put it in the incubator for later use;

[0034] Step 4: Check the condition of the solid medium in the white plate of the incubator every day. If the ...

Abstract

The invention discloses a method for preventing mildew of bamboo by using Aspergillus flavus. Taking advantage of the fact that Aspergillus flavus can consume more starch and reducing sugar than ordinary molds within a certain period of time, and will not significantly reduce the physical and mechanical properties of bamboo itself, inoculate Aspergillus flavus on bamboo to promote The starch and reducing sugar inside the bamboo are rapidly reduced, and finally the dark mold spots on the surface of the bamboo are removed by bleaching, and the beautiful color of the bamboo surface is restored. This technology includes the cultivation technology of Aspergillus flavus, the inoculation technology of Aspergillus flavus, the sterilization technology of Aspergillus flavus, and the bleaching technology of moldy bamboo. According to ASTM:? D4445-03? (Standard test method for the effect of fungicides on undried wood mildew and discoloration (laboratory method)) to verify the mildew resistance of bamboo: the bamboo is pre-stained with Aspergillus flavus and then bleached, and its mildew resistance is significantly improved. There was no mold growth during the 30 day test period.

Description

technical field [0001] The invention specifically relates to a method for preventing bamboo from mildew by using Aspergillus flavus. Background technique [0002] Due to the high content of non-cell wall substances (starch, reducing sugar, protein, fat, minerals, etc.) in bamboo, it is very easy to mildew during storage, transportation, processing and use, which affects its use value. Due to the limitations of the internal structure of bamboo, the traditional anti-mildew method of bamboo cannot achieve the desired anti-mildew effect. [0003] The proposed patent application takes advantage of the fact that Aspergillus flavus can consume more starch and reducing sugar than ordinary molds within a specified period of time, and inoculates Aspergillus flavus on bamboo to promote the rapid decline of starch and reducing sugar inside the bamboo. The bamboo treated with mold can be bleached to completely remove the dark mold spots on the surface of the bamboo and restore the beaut...
