A novel alkaliphilic, halotolerant, rod-shaped bacterium, designated strain YIM CH208(T), was isolated from a soda lake in Yunnan, south-west China. The taxonomy of strain YIM CH208(T) was investigated by a polyphasic approach. Strain YIM CH208(T) was Gram-negative, strictly aerobic and non-motile and formed red colonies. Optimal growth conditions were(More)
A Gram-negative, facultatively anaerobic, short rod-shaped, heterotrophic bacterium, designated strain YIM D21(T), was isolated from a salt mine in Yunnan province, south-west China. Strain YIM D21(T) formed cream-yellow colonies, was non-motile and moderately halophilic, and tolerated NaCl concentrations of 1-15% (w/v), with optimum growth at 5-10 % (w/v).(More)
Two rod-shaped, non-motile bacteria were isolated from two separate salt mines in Yunnan, south-western China. These strains, designated YIM D15(T) and YIM J21(T), were Gram-negative and moderately halophilic. The two strains required 6-10 % NaCl (w/v; optimal) for growth. The DNA G+C contents of strains YIM D15(T) and YIM J21(T) were 49.0 mol% and 48.4(More)
Two Gram-stain negative, moderately halophilic, aerobic, motile bacteria, designated strains YIM QH88T and YIM QH103, were isolated from the Qiaohou salt mine in Yunnan, southwest China. Cells of the strains were observed to be rod-shaped and produce creamy-coloured colonies. Growth of the two strains was observed at 10–45 °C (optimum 25–37 °C), at pH(More)
Although Halomonas phages belonging to the families Myoviridae and Siphoviridae have been reported, no virulent Halomonas siphoviruses are known. In this study, a virulent bacteriophage, QHHSV-1, of the family Siphoviridae that specifically infects H. ventosae QH52-2 was isolated from the Qiaohou salt mine. Restriction analysis indicated that QHHSV-1 is a(More)
A facultatively anaerobic, Gram-staining-negative, pale red-pigmented, non-motile, rod-shaped, moderately halophilic bacterium, designated strain YIM J14(T), was isolated from a sediment sample from a salt mine in Yunnan, south-western China. Growth occurred at NaCl concentrations of between 2 % and 15 % (w/v) and optimally with 5-9 % NaCl. The optimum(More)
Morus nigra has a long history of medicinal use in Chinese medicine, but the study on it is limited, the flavonoids are one of the main biological active substances. In this study, the Morus nigra flavonoids were extracted by ultrasonic and antioxidant activities both in vitro and in vivo were measured. The results showed that hydroxyl radicals clearance(More)
While much is known about the microbial diversity in some hypersaline environments, little is known about those of salt mine tunnel soils. The objective of this study was to conduct a comprehensive phylogenetic comparison of the archaeal and bacterial communities present in Yipinglang salt mine (YPL) and Qiaohou salt mine (QH) tunnels differing in salinity(More)
A novel, moderately halophilic, rod-shaped bacterium, designated strain YIM D17(T), was isolated from a sample of sediment from a salt mine in Yunnan, south-western China. The taxonomy of strain YIM D17(T) was investigated using a polyphasic approach. Strain YIM D17(T) was Gram-stain-negative, strictly aerobic and non-motile and formed pink colonies on(More)
OBJECTIVE To investigate the changes in the activity of Escherichia coli asparaginase (L-asp) and the concentration of asparagines (ASN) in the plasma of the acute lymphoblastic leukemia (ALL) children receiving L-asp containing chemotherapeutic protocol to explore more reasonable usage of L-asp in the treatment of childhood ALL. METHODS L-asp containing(More)
