(5)实验方法：(5) Experimental method:
①实验样片的预处理：将制成的各组样片侵入75％乙醇中,消毒30min取出,室温下自然干燥过夜后,移入干燥器0.5h,称重量至恒重,记录初始质量。① Pretreatment of experimental samples: Invade each group of samples in 75% ethanol, sterilize them for 30 minutes, take them out, dry them naturally at room temperature overnight, then transfer them to a desiccator for 0.5 hours, weigh them to a constant weight, and record the initial mass.
②倒板：将基础无碳源琼脂培养基加热溶化倒进平皿,每平皿培养基深度8～10mm；② Pour plate: Heat and melt the basic carbon-free agar medium and pour it into a plate, the depth of each plate is 8-10mm;
③接种：在生物安全柜内将第3组的各样片分别置于无菌平皿内,再用美术喷枪分别将0.2ml霉菌悬液喷于各样片表面；③Inoculation: Place the samples of the third group in sterile plates in the biological safety cabinet, and then spray 0.2ml of mold suspension on the surface of each sample with an art spray gun;
④加实验样片：将染菌的各样片静置1min后以无菌程序将其置于预先制备好的平皿培养基表面,同时做不染菌对照组和零对照组。每组3皿,每皿2片。要避免样片之间、样片与平皿之间接触；④ Adding test samples: Let the samples contaminated with bacteria stand for 1 min, and then place them on the surface of the pre-prepared culture medium in a sterile procedure. 3 dishes in each group, 2 slices in each dish. Avoid contact between samples, between samples and plates;
⑤培养：将接种好的第3组及不接种的第2组平皿用胶带封好,置霉菌培养箱中。保持培养箱30℃,相对湿度>90％,培养28天。培养箱每周换气1次。零对照平皿在实验室自然放置。每周取出1片试样称重并做好记录；⑤Cultivation: Seal the plates of the inoculated third group and the uninoculated second group with adhesive tape, and put them in the mold incubator. Keep the incubator at 30°C, relative humidity >90%, and cultivate for 28 days. The incubator was ventilated once a week. The zero control plate is naturally placed in the laboratory. Take out one piece of sample every week, weigh it and make a record;
⑥质量损失率测定：取出样片，用75％的酒精消毒,然后用85℃的蒸馏水清洗后,在干燥器中干燥直到恒重,称量并记录此时各样品的质量,计算质量损失率；⑥ Determination of mass loss rate: Take out the sample, disinfect with 75% alcohol, then wash with 85°C distilled water, dry in a desiccator until constant weight, weigh and record the mass of each sample at this time, and calculate the mass loss rate;
质量损失率是评价样品生物降解性能的重要指标之一,它等于试样生物降解试验后平均质量损失除以原始试样的平均质量的百分率,计算公式如下：The mass loss rate is one of the important indicators for evaluating the biodegradation performance of the sample, which is equal to the percentage of the average mass loss of the sample after the biodegradation test divided by the average mass of the original sample, and the calculation formula is as follows:
D＝(m0-mt)/m0×100％D=(m0 -mt )/m0 ×100%
式中m0为试样原始质量；mt为试样降解后的质量。In the formula, m0 is the original mass of the sample; mt is the mass of the sample after degradation.
样品降解后质量损失率越大,其生物降解性越好，本发明实施例1、2、3、4制备的缓冲包装材料的质量损失率的结果见表1.The greater the mass loss rate after the sample is degraded, the better its biodegradability. The results of the mass loss rate of the cushioning packaging materials prepared in Examples 1, 2, 3, and 4 of the present invention are shown in Table 1.
表1质量损失率测定结果Table 1 Mass loss rate measurement results
