Nomuraea rileyi (Farlow) Samson is an entomopathogenic fungus capable of producing a variety of enzymes including proteases and chitinases. Protease derived from microorganisms such as fungi, bacteria, and yeast has established wide spread applications in fields such as in the food, detergent and other industries. This study investigates the strategy for partial purification and characterizatio...

Abstract Keratinase is a robust enzyme that produced in the presence of keratin substrates. This has been recognized for its applications waste management, leather and detergent industries. Our group isolated potential keratinase producing strain Bacillus aerius NSMk2 from poultry dump soil, hide dehairing stain removal have studied. Considering commercial applicability keratinase, present stud...

Protease executes a large variety of functions and it has many biotechnological applications. It represents as one of the third largest group of industrial enzyme and finds its applications in detergents, leather industry, pharmaceutical industry etc. Among the different vegetable waste products, peel of Manihot esculenta (Tapioca/ cassava) was used as substrates for the production of protease ...

The objective of this study was to characterize Salmonella enterica contamination on carcasses in two large U.S. commercial pork processing plants. The carcasses were sampled at three points, before scalding (prescald), after dehairing/polishing but before evisceration (preevisceration), and after chilling (chilled final). The overall prevalences of Salmonella on carcasses at these three sampli...

In order to evaluate the relationships between deck level, body surface temperature and carcass damages after a short journey (30 min), 10 deliveries of Italian heavy pigs, including a total of 1400 animals from one farm, were examined. Within 5 min after the arrival at the abattoir, the vehicles were unloaded. Environmental temperature and relative humidity were recorded and a Temperature Humi...

Introduction Beef carcasses, which are initially sterile, become contaminated with bacterial pathogens via transmission of organisms from the exterior of the live animal, and/or from the environment, to the product surface. Extensive contamination, or abusive conditions that allow bacteria to reproduce, increase risk for presence of pathogenic bacteria and formation of toxins in food (Sofos et ...

Alkaline crude enzymes from the viscera of the Tunisian barbel (Barbus callensis) were extracted and characterized. Proteolytic crude extract from barbel viscera was active and stable in alkaline solution. The optimum pH and temperature were 11.0 and 55 °C, respectively, using casein as a substrate. The crude alkaline protease was extremely stable in the pH range of 5.0-12.0. Zymography activit...

Among different types of controlling systems, the ON/OFF digital relative humidity control was used for measuring electrical properties of cashmere fibers to make the ambient relative humidity fixed. To achieve this goal the required hardware and software were designed and fabricated. The electrical resistance of fine and coarse hair cashmere fiber was measured by charge and discharge condenser...

Mohair from Angora goats has been produced in the United States since the introduction of these animals from Turkey in 1849. Cashmere on Texas meat goats was reported in 1973, but domestic interest in commercial production did not occur until the mid-1980s. Since 1982, the average prices of U.S.-produced mohair and cashmere (de-haired) have ranged from $1.81 to $9.48/kg and approximately $55 to...
