Environmental parameters drive phenotypic and genotypic frequency variations in microbial communities and thus control the extent and structure of microbial diversity. We tested the extent to which microbial community composition changes are controlled by shifting physiochemical properties within a hypersaline lagoon. We sequenced four sediment metagenomes from the Coorong, South Australia from...

Background and Aim: Swimming in non-standard and unhygienic pools is one of the important health problems, which results in transmission of disease in swimmers. In case of unhygienic pools, diseases such as conjunctivitis, swimmer foot itching, skin diseases, typhoid disease, trachoma and fungal diseases may occur. The present study was aimed to evaluate the microbial and physicochemical circu...

Microbial cells are producers of natural polymers present in plant cells. Production of pullulan (an extracellular microbial polysaccharide) by Aureobasidium pullularia pullulans (P. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. Pullulan formation obeyed a growth and non-growth associated term. PHB (polyhydroxybutyrates) an intracellular biopo...

Background and Objectives: Each patient has renal failure in any dialysis with high water volume, which is in direct contact with the patient's blood. The presence of any chemical and microbial contamination in water used in homodynamic devices can be very dangerous for these patients. The purpose of this study was to determine the efficiency of reverse osmosis open systems in improving the wat...

In this study, the addition of microbial transglutaminase (MTG) and lipase in quark cheese samples was studied during storage (21 d). Four types were made using 3 different levels MTG (T1, 0.1 g/L; T2, 0.2 T3, 0.3 g/L) 0.02 0.04 0.06 g/L), one without any treatment as a control sample. The physicochemical, textural, microbial, sensory properties monitored at 1, 7, 14, 21 d period. results showe...

there has been a gradual shift of focus from the study of rule systems, which have increasingly been regarded as impoverished, … to the study of systems of principles, which appear to occupy a much more central position in determining the character and variety of possible human languages. there is a set of absolute universals, notions and principles existing in ug which do not vary from one ...

The present study aimed to characterize five commercial honeys available in the Portuguese market in respect to their floral origins, physicochemical parameters and microbial safety and commercial quality assessment. Pollen profile, colour, moisture content, ash, acidity, electrical conductivity, pH, reducing sugars, apparent sucrose and HMF were the parameters analysed in each honey sample. Ae...

AIMS This study investigates changes in microbiological and physicochemical parameters during large-scale, thermophilic composting of a single batch of municipal organic waste. The inter-relationships between the microbial biomass and community structure as well as several physicochemical parameters and estimates of maturation were evaluated. METHODS AND RESULTS Analyses of signature fatty ac...

Dormancy is an essential strategy for microorganisms to cope with environmental stress. However, global ecosystem models typically ignore microbial dormancy, resulting in notable model uncertainties. To facilitate the consideration of dormancy in these large-scale models, we propose a new microbial physiology component that works for a wide range of substrate availabilities. This new model is b...
