Fermentation of paocai is a dynamic process the microbial community structure, and interaction between structure physicochemical factors endows with unique taste flavor. The study bacterial fungal changes driving mechanism induced in showing that Pseudomonas belonging to Proteobacteria Lactobacillus Firmicutes were dominant bacteria fermentation. correlation analysis showed titratable acid was ...

Today’s rapid development of powerful tools for gene expression analysis provides unprecedented resources for elucidating complex molecular events. The objective of this work has been to apply, combine and evaluate tools for analysis of differential gene expression using atherosclerosis as a model system. First, an optimised solid-phase protocol for representational difference analysis (RDA) wa...

The Qiantang River is a typical freshwater ecosystem that acts as an irreplaceable water source in Zhejiang Province in southeastern China. However, the effects of environmental factors on the bacterial community of this freshwater ecosystem have not been determined. In this study, seven sediment samples were collected along the river. Their bacterial communities were identified using 454 high-...

Soil microorganisms are greatly affected by their microenvironment. To reveal the influence of different land use patterns on composition and diversity soil bacterial fungal communities, this study analyzed microbial (bacteria fungi) community under (vegetable land, wasteland, woodland, cultivated land) based 16S rRNA, 18S high-throughput sequencing method in Taojia River Basin. Spearman analys...

The relationship between the diatom taxa preserved in surface lake sediments and environmental variables Dongping Lake was explored using multivariate statistical methods. analysis showed that eutrophicated all seasons. Transparency, chlorophyll a (Chla) total phosphorus (TP) were dominant factors spring summer, NH4+-N chemical oxygen demand (COD) autumn winter. Sixteen genera 43 species of fou...

Keystone taxa play an important role in soil nutrient cycling and crop growth can be influenced by tillage. We investigated the composition of keystone their relationships with properties under different long-term tillage practices. Four treatments (i.e., CT, conventional tillage; NT, no mulch; RT, reduced SS, subsoiling mulch) were maintained for twenty-one years. Co-occurrence network (CoNet)...

Soil properties affect plant growth and cause variation in leaf functional traits. Lycium ruthenicum Murray is one of the desert dominant shrubs halophytes lower reaches Heihe River, Northwest China. We analyzed trade-off relationships 14 traits eight L. populations growing at varying distances from river discussed effects that soil have on The results showed that: Lower nitrogen (N) content in...

Random amplified polymorphic DNA (RAPD) markers were used to study the spatial genetic structure in two populations (Bolarque and Entrepeñas) of endangered cliff specialist Antirrhinum microphyllum Rothm. (Scrophulariaceae). Mantel tests found no significant linear correlations between geographic and genetic data. However, redundancy analysis (RDA) models developed using the spatial data as the...

OBJECTIVE Current dietary guidelines recommend adequate intake of magnesium (310-420 mg daily) in order to maintain health and lower the risk of cardiovascular disease. Recent evidence from animal and clinical studies suggests that magnesium may be associated with inflammatory processes. The objective of this study was to determine whether dietary magnesium consumption is associated with C-reac...

Understanding patterns in forest communities and its driving factors play a critical role ecological studies. In view of this, present study attempts to understand the environmental anthropogenic towards shaping species diversity composition along altitudinal gradient (700–3800 m asl) Indian western Himalaya. A total 51 tree (28 families) were recorded; Pinaceae (5) Fagaceae rich families. ?-di...
