considering the potential benefits of edible coatings and films for storage of food materials, effect of edible calcium alginate film on shelf life of frozen lamb muscles was studied in the present research. microbial analyses including total microorganisms count and psychrophilic bacteria count and chemical analyses such as total volatile nitrogen (tvn) and moisture content determination were ...

Introduction: Nanotechnology is one of great important part of technology. Nanoparticles can be used in different applications for industrial, medical, military and personal use. The objectives of this study were preparation of chitosan –ZnO nanocomposite films via a simple method and investigation of antibacterial activity of them. Methods: Chitosan –ZnO nanocomposites were prep...

In the present research the antimicrobial activity of two active packaging materials on the spoilage microbiota of fresh salmon fillets was tested. A PET-coated film (PET: Polyethylene Terephthalate) containing lysozyme and lactoferrin was tested in parallel with a carvacrol-coextruded multilayer film. Salmon fillet samples were stored up to four days at 0 and 5 ̋C, comparatively. The carvacrol...

INTRODUCTION Blepharitis and meibomian gland dysfunction are chronic inflammatory conditions with overlapping pathophysiology and symptomatology. Both microbial infection and seborrhea contribute to the pathophysiology and both may benefit from treatment with tea tree oil (TTO). We evaluated the therapeutic effect of eyelids scrubbing with TTO in a group of patients with lid margin disease. M...

The upflow anaerobic sludge blanket (UASB) reactor has been used successfully treat a variety of wastewaters. The aim of this review is to synthesize and analyze information on how the process of granulation is affected by environmental and operational conditions in the reactor. The factors reviewed are strength of substrate, nutrients, multivalent cations and heavy metals, exocellular polymer,...

Pilgrim Hot Springs has a known shallow geothermal reservoir with temperatures approaching 91 ̊C in the top 100 meters of the system that underlies the main hot springs area of 1.5 km. The deeper reservoir is less understood with similar temperatures at the basement surface 320 meters directly beneath the hot springs. The aspect of this research is to create a stratigraphic model and delineate p...

High-rate anaerobic digestion can be applied in upflow anaerobic sludge blanket reactors for the treatment of various wastewaters. In upflow anaerobic sludge blanket reactors, sludge retention time is increased by a natural immobilization mechanism (viz. the formation of a granular type of sludge). When this sludge is cultivated on acid-containing wastewater, the granules mainly consist of an a...
