reuteri 1 × 108 CFU/ml for 2 h (37 °C, 5% CO2). In the SE PT4 infected group, explants were treated with culture medium containing Salmonella Enteritidis PT4 at a concentration of 1 × 107 CFU/ml, incubated for 2 h (37 °C, 5% CO2). In the pre-treatment experimental...
rosea AUMC15121, at 1107 CFU/ml, effectively managed R. solani-induced root and basal stem rot in lucky bamboo, demonstrating superiority over the fungicide Moncut and providing a chemical-free approach to disease control. This report also details the initial isolation and identification of ...
盆栽试验结果显示，添加108 cfu/mL 真菌，土壤pH 值比对照显著降低了0.35个单位；对碎米荠幼苗生长无不良影响，平均株高为7.4 cm ，平均根长为9.6 cm ，平均生物量为2.9 g ，均高于对照；土壤中有效硒的含量显著提高，活硒率最高达到2 4.8%，而有效镉的含量显著降低，抑镉率达到24.7%；碎米荠地上/...
Under optimized conditions, the peak current response of the LIP sensor showed a linear relationship with the logarithmic value of LGG concentration in the range from 101 to 109 CFU mL−1 and a detection limit of 5 CFU mL−1. The proposed LIP sensor has achieved efficient, ultrasensitive,...
pylori strain 1 at a concentration of 108 colony-forming units (CFU) in 1 mL, another group was treated with H. pylori strain 2 at the same concentration, and the third group received 1 mL of saline as the control group via gavage administration. After a duration of 73 weeks, all ...
The capability to supply exopolysaccharides was screened in chosen lactic acid micro organism (LAB) isolates. Production of natural acids in the spontaneous fermentation dropped the pH to 4.0 ± 0.3. The group of presumptiveLABreached 8.37 ± 0.01 log colony forming models (CFU)/mL by day 8 of...
(3)GES-1细胞与Hp共同培养,取处于对数生长期的GES-1细胞0.25%胰酶消化后进行细胞计数,将1×106个GES-1细胞铺于底面积为25 cm2细胞的培养瓶中,用无抗生素含10%FBS的RPMI-1640培养基常规培养过夜,次日晨用无抗生素含10%FBS的RPMI-1640培养液调节Hp浓度为1×108CFU/mL,按细胞与细菌比例为1:1分别加入Hp,置于...
We added 2.5% L.P dy-1 (4 × 108 cfu/mL) to the barley flour with seven-times deionized water to ferment at 30 ℃ for 24 h. After centrifugation (8, 000 ×g for 20 min), the supernatant of the fermented liquid was dried with vacuum freeze drier (Marin Christ, Germany) and ...
Turbidity assay: Turbidity were determined by using 0.1mL of suspensions of P. aeruginosa bacteria (Standard 27853 ATCC) and sample from patients with burns (3×108 CFU/mL) in tubes containing 10mL of BHI solution and the same amounts of Kefir. Tubes were mixed using a vortex for 60 s ...
A.3.3成果计算:菌落数(CFU)/件=2个平皿菌落数平均值×10。第119页A.4合格原则A.4.1消毒合格原则:细菌总数≤20cfu/件。A.4.2灭菌合格原则:未检出细菌(无菌检查合格)。A.5致病菌检测A.5.1应在可疑经软式内镜诊断操作导致感染时进行检测。A.5.2检测办法:在进行细菌总数检测旳同步,取混匀旳待检样品0.2ml,分别...
