The aim of this paper was to synthesize and characterize microbial chitosan thin films for potential piezoelectric application. Microbial derived from the Aspergillus oryzae fungus via extraction deacetylation. Chitosan film characterized its surface morphology, chemical properties, tensile strength, topography. For application as a material, characteristics were presented in terms electromecha...

Introduction: Microbial contamination prediction through detecting the indicator bacteria in natural waters is the first health and environmental step for preventing the transmission of water-associated diseases. This study was designed to determine the correlation between Escherichia coli as the indicator bacterium, on the one hand, and Salmonella and Shigella Spp. As the pathogenic bacteria, ...

MOTIVATION Characterizing the diversity of microbial communities and understanding the environmental factors that influence community diversity are central tenets of microbial ecology. The development and application of cultivation independent molecular tools has allowed for rapid surveying of microbial community composition at unprecedented resolutions and frequencies. There is a growing need ...

Drawing on a long history in macroecology, correlation analysis of microbiome datasets is becoming a common practice for identifying relationships or shared ecological niches among bacterial taxa. However, many of the statistical issues that plague such analyses in macroscale communities remain unresolved for microbial communities. Here, we discuss problems in the analysis of microbial species ...

BACKGROUND If a fixed stress is applied to the three-dimensional z-axis of a solid material, followed by heating, the amount of thermal expansion increases according to a fixed coefficient of thermal expansion. When expansion is plotted against temperature, the transition temperature at which the physical properties of the material change is at the apex of the curve. The composition of a microb...

The objective of this study was the in vitro evaluation of the effect of a cell-free microbial supernatant, produced by a luxS-positive Salmonella enterica ser. Typhimurium strain, on the single-cell growth kinetic behavior of two strains of S. enterica (serotypes Enteritidis and Typhimurium) and a methicillin-resistant Staphylococcus aureus strain. The single-cell lag time (λ) of the pathogens...

in order to complete the microbial control of the sawthoothed beetle by the fungus beauvaria bassiana (isolate 441c) in ipm program of stored date, 9 edible and commercial vegetable oils including canola, soybean, sesame, corn, coconut, grape seed, olive, sunflower and almond were investigated to formulate the fungus. results showed that b. bassiana formulated with sesame oil was the most suita...

Background & Aims of the Study: Given the importance of microbial contamination in creating food-borne diseases, this study was conducted to assess level of microbial contamination of pastry creams in Hamedan, Iran. Materials and Methods: Totally, 80 samples were randomly collected from the confectioneries and analyzed for microbial contamination according to Iranian nati...
