Drying Pickering o/w emulsions has been considered as a promising strategy to produce oil microcapsules, long their quality parameters can be preserved over storage. In this sense, it is shown an interesting alternative preserve the of roasted coffee oil, valuable agroindustrial byproduct. Thus, freeze- and spray-dried chitosan-based were evaluated 30 days storage at 25 °C together with non-enc...

The L-forms of Clostridium perfringens were first reported by Dienes (1950). He described this form as minute, soft, pleomorphic colonies which developed when C. perfringens were grown on penicillin-treated horse serum agar plates. The reversion of L-colonies to bacterial forms has not been reported for C. perfringens. They have been observed in strains of Proteus (Dienes, 1949), Salmonellae (W...

When two different strains of swarming Proteus mirabilis encounter one another on an agar plate, swarming ceases and a visible line of demarcation forms. This boundary region is known as the Dienes line and is associated with the formation of rounded cells. While the Dienes line appears to be the product of distinction between self and nonself, many aspects of its formation and function are unc...

An assessment of three simple methods of typing Proteus strains is described. The methods chosen were biochemical typing, bacteriocine typing, and typing by means of the Dienes phenomenon. Dienes typing was deemed to be superior to biochemical typing and bacteriocine typing.A brief discussion on the relationship between the Dienes phenomenon and bacteriocine production is appended.

The aim of this study was to compare the effects of solvent and ultrasound-assisted extraction methods with supercritical fluid extraction on antioxidant activity of loquat (Eriobotrya japonica Lindl.) fruit skin extract in stability of soybean oil at 25°C. Oxidative stability alterations of soybean oils containing 400 (SEA) and 1000 ppm (SEB) of ethanol extract, 400 (SSA) and 1000 ppm (SSB) of...

The effect of long-term administration of alcohol and cigarette smoke independently and both in combination on lipid peroxidation and antioxidant enzymes, such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione-S-transferase (GST) was studied in liver, kidney, heart and lungs of albino rats. The levels of peroxidation products viz., malondialdehyde, hyd...
