Bacillus subtilis B6-1 was used as an original strain for mutagenic treatment and a defined medium was used as the selective medium. A mutant named B. subtilis W003 was isolated after three serial ultraviolet (UV) irradiations and one diethyl sulfate (DES) treatment. The ?-PGA yield on a rotary shaker was enhanced from 10.9 g/L in parental strain to 20.5 g/L in the mutant. It was illustrated by single factor experiments that the optimal carbon and nitrogen sources were glucose and (NH4)2SO4 respectively. The optimal fermentation medium was achieved by orthogonal test. In the optimal medium, a ?-PGA yield of 45.3 g/L was obtained after 36 h cultivation.

AlM: To study the clinical effect of the application of microscopic pterygium resection combined with different concentration of mitomycin C ( MMC) .
METHODS:A total of 110 cases of pterygium patients (120 eyes) were randomly divided into control group (58 eyes) and observation group (62 eyes) according to the odd and even number method. The control group adopted the pterygium resection combined 0. 3mg/mL MMC, and the observation group was given pterygium resection combined 0. 2mg/mL MMC. The cure rate and the recurrence rate, eyesight before and after the treatment, two groups of cornea and sclera wound healing situation, the incidence of postoperative complications were compared.
RESULTS: The cure rate and recurrence rate of the control group was 84. 5% and 15. 5% respectively, and the observation group was 93. 6% and 6. 5% respectively, the differences were statistically significant (P<0. 05). There were statistical differences of vision of the two groups before and after treatment (P<0. 05), and there were no statistical differences of the two groups between the two groups after treatment (P>0. 05). The cornea, sclera, wound healing time of the observation group were less than the control group, and there were statistical differences between the two groups ( P < 0. 05 ). The incidence of complications was 13. 8% in the control group and 3. 2% in observation group, with statistically significant difference (P<0. 05).

Objective To evaluate the performance of energy discriminating dosimeter and compare the impact of the assessment results. Methods CTLD-J4000 energy discriminating dosimeter was irradiated with different energy photons, and the differences covered by the dosimeters were used. Density filtering materials have different filtering effects on photons, and the ratio curve of the readings to the photon energy was fitted to identify the photon energy. Results The coincidence between the non-filter/light filter of the CTLD-J4000 energy discrimination dosimeter and the manufacturer's reference value was better than that of the non-filter/re-filter. The latter had higher deviation values at 48 keV(12.8%)and 83 keV(15.5%), respectively. Using the average scale factor, the maximum energy response deviation was 23.5%. Conclusion Using a discriminating dosimeter can better identify the ray energy, thereby reducing the energy response error caused by using the average scale factor.
