Bacterial cellulose is produced by several species of Acetobacter and because of its unique properties; it has advantages over plant cellulose. Today, this biopolymer has numerous applications at many industrial fields. In this research, samples from different sources of Iran were collected and cultivated in an enrichment liquid medium for growth of acetic acid bacteria. After purification the ...

Advancement of Nucleic Acid-Based Tools for Monitoring In Situ Reductive Dechlorination Vangelas, K., E. Edwards, F. Loeffler, B.B. Looney. Paper No: WSRC-STI-2006-00332, 23 pp, Nov 2006 Regulatory protocols generally recognize that destructive processes are the most effective mechanisms that support natural attenuation of chlorinated solvents. In many cases, these destructive processes will be...

Tauco is one kind of traditional fermented food from Indonesia. processed soybean paste with a salty taste andcommonly has yellow and black color. Generally, tauco used as spice or seasoning in various daily dishes. The study aimsto find identify the bacteria that produced fibrinolytic enzymes tauco. sample this research sixdifferent manufacturers. Two tests have to do study: proteolytic test S...

Background and Aim: Prolonged stress causes deleterious effects on both the organism its microbiota. In this study, we examined of exposure to variable frequency ultrasound (US) gut microbiota-liver-brain axis mice. Materials Methods: This study was conducted 20 mature clinically healthy sexually naive C57BL/6J male mice (42–45 days old). Group 1 (Normal) consisted intact (n = 10). 2 (Stress) s...

Free fatty acid (FFA) is one of the pathogenic factors in acne vulgaris. However, how FFAs interact with skin microbiome and host immunity still unclear. To clarify this, we comprehensively investigated lesions developed a novel mouse model. First, measured severity amounts (C12-C24) healthy- acne-forehead (50 females, aged 20-40 years). The total palmitic (PA) were weakly correlated number inf...

Inflammatory bowel diseases (IBD) are chronic conditions arising from an intricate interplay of genetics and environmental factors, associated with gut dysbiosis, inflammation, permeability. In this study, we investigated whether the inflammatory potential diet is microbiota profile, permeability in forty patients IBD clinical remission. The dietary index (DII) score was used to assess diet. fe...

This study sought to clarify the composition of soil fungal and bacterial communities along an elevation gradient in arid montane ecosystem as well influence environmental factors (soil properties, climate, topography, plant diversity) upon microbial community structures. Four vegetation types—montane desert steppe (mean elevation: 1761 m), shrub 2077 subalpine coniferous forest 2485 2903 m)—we...

The treatment of rural sewage has become an important part environmental protection. In this study, a novel waterwheel-rotating biological contactor (WRBC) system, with intensified biofilm and high-shock load resistance, was applied to treat sewage. When the COD concentration actual fluctuated between 79–530 mg/L, removal efficiency 41.3–94.5%, NH4+-N always reach 100% TN changed 14.3–86.2%, wh...

BACKGROUND Staphylococcus aureus is a common and significant pathogen in cystic fibrosis. We sought to determine if quantitative PCR (qPCR) and 16S rRNA gene sequencing could provide a rapid, culture-independent approach to the identification of S. aureus airway infections. METHODS We examined the sensitivity and specificity of two qPCR assays, targeting the femA and 16S rRNA gene, using cult...
