In order to study the effects of long-term different fertilization on microbial community functional diversity in arable black. soil, we examined microbial metabolic activities in two soil la- yers (0-20 cm, 20-40 cm) under four treatments (CK, NPK, M, MNPK) from a 35-year continuous fertilization field at the Ministry of Agriculture Key Field Observation(More)
In this study, determination of heavy metal parameters and microbiological characterization of marine sediments obtained from two heavily polluted sites and one low-grade contaminated reference station at Jiaozhou Bay in China were carried out. The microbial communities found in the sampled marine sediments were studied using PCR-DGGE (denaturing gradient(More)
The effect of mixed culture on the anti-fungi activity of marine microbes metabolites was evaluated. Based on optimization of monoculture, orthogonal design was used to approach the optimal region of the medium composition of mixed fermentation. The mixed culture showing anti-fungi activity of marine microbes was enriched obviously, compared with(More)
