Estimating and comparing microbial diversity are statistically challenging due to limited sampling and possible sequencing errors for low-frequency counts, producing spurious singletons. The inflated singleton count seriously affects statistical analysis and inferences about microbial diversity. Previous statistical approaches to tackle the sequencing errors generally require different parametr...
The most common used methods for water disinfection were chemicals like chlorine, ozonation, ultraviolet radiation, membrane processes, etc. Water disinfection using irradiation techniques is new in water treatment industry which has been developed recently. The aim of the present study was to investigate radio frequency (RF) efficiency for the inactivation of total coliform (TC), fecal colifor...
milk and dairy products are important components of a balanced diet. milk does have distinct physicochemical, biological and microbial characteristics. the bacterial contamination of milk not only reduces the nutritional quality but its consumption threatens health of the society. in this study, 100 pasteurized milk samples were collected randomly from tabriz city, northwestern and were analyze...
Background and purpose: There is a high risk of pathogen contamination in poor quality cosmetic products that are illegally smuggled into our country. Such contaminations can be easily passed to consumers and endanger their health. In this study the microbial contamination were investigated in some nonstandard moisturizing creams found in poor quality markets and standard creams from drug store...
Background. Fresh vegetables such as tomato should have low microbial population for safe consumption and long storage life. The aerobic bacterial count (ABC) and coliform bacterial count (CBC), yeast, and mold population are the most widely used microbial indicators in fresh vegetables which should be lower than 4 log CFU g-1 for safe consumption. The stages of the supply chain, postharvest ha...
The study was conducted in Addis Ababa town, central Ethiopia. To assess the general milk handling practice, determine physicochemical properties and evaluate the microbial quality of raw cow milk produced through the milk sheds found in the town. A cross sectional study was conducted in the study area and then purposively based on dairy potential three sub cities i.e., Akaki-Kality, Nifas Silk...
this study investigated of antibacterial and antioxidant activity of garlic and lemon extract (1.5 %) on the quality and shelf life of fillet, vacuum-packaged rainbow trout (oncorhynchus mykiss) during refrigerated storage. were studied by monitoring the microbiological (totalviable count, psycrotrophic), chemical (tba), ph and sensory changes for a period of 20 days in (0, 5, 10, 15 and 20). e...
background: although enteral feeding solutions are used to reduce the morbidity and mortality in many malnourished and hospitalized patients, microbial contamination of these products may lead to severe infections, especially in immune suppressed ones. the aim of this study was to evaluate the microbiological quality of commercial enteral feedings in two hospital settings in shiraz. methods: tw...
Background and objectives: Swimming is one of the most popular sport fields and entertainments that has considerable benefits for human health, but on the other hand microbial water contamination in swimming pools through transmission and spread of infectious diseases is a significant threat against public health. In this study, microbial water quality of all public swimming pools in Tehran wer...
Using natural extracts, as a source of anti-microbial, to improve the quality of fish is increasing. In this study, the ethanolic extract of orange (Citrus sinensis L.) was used due to having this property. Agar dilution method was employed in order to determine the minimum inhibitory concentration (MIC) of the ethanolic extract of orange peel on Pseudomonas aeruginosa, E. coli and Aeromonas hy...
