Microbial growth on the surface of a valve of a voice prosthesis and optionally the cartridge or ring supporting the valve, is inhibited by providing antimicrobial activity at a level sufficient to retard growth of a microbial film by dispersing an inorganic antimicrobial agent such as silver oxide or an organic antimicrobial agent such as triclosan or butyl paraben dispersed in a medical grade silicone elastomer. The valve, ring or cartridge is in contact with body fluids containing microorganisms and nutrients therefor. The antimicrobial surface can interfere with or inhibit the growth of a biofilm, bacterial layer or a yeast layer. The body of the prosthesis may also contain an antimicrobial surface as long as it is non-toxic to the tissue it contacts.

The invention discloses a test tube bulblet reproduction method of lilium leucanthum, belonging to the field of biology. The invention aims to provide the test tube bulblet reproduction method of lilium leucanthum, so as to solve the problem that existing common methods for lily tissue cultivation cause slow growing of seedlings of lilium leucanthum. The method comprises steps of sterilizing of scale explants, inducing the test tube bulblet, expanding and root growing of the test tube bulblet, and germinating and growing of the bulblet. A bulblet induction culture medium comprises a base culture medium and hormones, wherein the base culture medium is prepared from a MS base culture solution, 60g / L of sucrose, 0.5g / L of arginine phosphokinase, 0.5g / L of glutamine, 2g / L of active carbon, 6g / L of agar, 500mg / L of dithiothreitol and 300-800mg / L of butylparaben. The test tube bulblet reproduction method of lilium leucanthum has the advantages of high reproduction coefficient, short cultivation cycle, high efficiency, high transplant survival rate, convenient transportation, easy operation and low cost.

The present invention discloses an anticorrosion and preservation compound preparation. The compound preparation comprises the following components in parts by weight: 1-5 parts of epsilon-polylysine, 1-5 parts of butylparaben and 0.2-0.8 part of rosemary essence oil, 5-20 parts of chitooligosaccharides and 1-5 parts of EDTA disodium. The present invention also discloses an application of the anticorrosion and preservation compound preparation in the anticorrosion of low-temperature meat products. Compared with the prior art, the compound preparation is simple in preparation, very good in the thermal stability, and favorable for heat treatment of prodcuts before leaving the factory, reduces the number of initial bacteria when leaving the factory and prolongs the shelf life of the products. In addition, the compound preparation is convenient in use and wide in application range, and has great practical significances to expand the bacterium inhibition spectrum, exert the best effects and conform to the development trend of food additives.

The invention discloses an environment-friendly anti-mildew treatment method for bamboo, which comprises the steps of S1 ultrasonic treatment of bamboo to remove green and yellow, the ultrasonic frequency is 50KHz-100KHz, the ultrasonic power is 400-800W, and the ultrasonic temperature is 20-80°C; S2 Use sodium acetate and butylparaben or sodium diacetate and butylparaben or sodium diacetate and propylparaben to prepare compound antifungal agent; S3 uses No. 58 food paraffin, 2‑hydroxy‑1, 4 naphthoquinone, Tween 60 and distilled water are used to configure compound paraffin wax emulsion; the present invention utilizes the thermal effect and mechanical effect of ultrasonic wave to destroy starch and inclusions in bamboo, and combines food-grade anti-fungal agent and food-grade paraffin wax. Bamboo materials can not only be applied to anti-mildew treatment of common daily-use bamboo products such as bamboo barrels, bamboo chopsticks, bamboo cutting boards, bamboo toothbrushes, etc., but also can greatly improve the dimensional stability, mechanical properties, hardness and wear resistance of bamboo materials. and hydrophobicity.
