通过滤纸片法和液体培养比浊法对食醋、蒜醋提取液、蒜水提取液的抑菌作用进行研究,结果表明:食醋对细菌具有较强的抑制作用,对真菌的抑制作用较弱,低浓度(3.2×10-4)食醋无抑菌作用。蒜水提取液和蒜醋提取液对细菌、真菌都有较强... 通过滤纸片法和液体培养比浊法对食醋、蒜醋提取液、蒜水提取液的抑菌作用进行研究,结果表明:食醋对细菌具有较强的抑制作用,对真菌的抑制作用较弱,低浓度(3.2×10-4)食醋无抑菌作用。蒜水提取液和蒜醋提取液对细菌、真菌都有较强的抑制作用,但蒜醋提取液抑菌活性略逊于蒜水提取液。 展开更多

Garlic peel,as the raw material,was modified by loading with zirconium(IV),exhibiting quite good uptaking behaviour for fluoride anion.The adsorption experiments were carried out in batch shaking vessels,and the process was strongly dependent on the pH value.The adsorption fits Langmuir model well,and the maximum adsorption capacities at equilibrium pH 2 and 6 are evaluated to be 1.10 and 0.89 mol(fluoride)/kg of Zr-loaded garlic peel gel,respectively.The evaluation of effects of coexisting anions such as nitrate,sulfate and phosphate shows that nitrate and sulfate have no negative effect on the adsorption of fluoride,while phosphate has a little effect.Adsorption kinetics of fluoride is well described by pseudo-second-order rate equation,and the corresponding adsorption rate constant is calculated to be 3.25×10?3 g/(mg·min). 展开更多

This study evaluated the germination of six crops, including four mutant lines of barley (Hordium vulgate L.) (1-9-3, 150-2-3, 1-1-200 and 150-1-5), wheat (Triticum aestivum L.) and garden cress (Lipidium sativum L.). This experiment was conducted in laboratory at room temperature. Oil extracted from crude oil contaminated soil was added to sand used in different concentrations (0%, 2%, 4%, 6%, 8% and 10%). 10 seeds of each crop were sown in ptri-dishes with different treatments separately. For Each treatment four replicates were used in completely randomized design, germination percent was calculated, after one week, shoot and root length were measured. Data were statistically analyzed using MINTAB version 12. The results show that barley mutant line (150-2-3) was significantly different from other entries in germination percent, shoot and root length except mutant line 150-1-5 in germination percent. Results demonstrated that the mutant line 150-2-3 was promising to remediate crude oil contaminated soil. 展开更多
