background: fillet is a popular part of chicken carcass which its high perishability is an economic problem. the present research was designed to study the microbial, chemical, and sensorial properties of chicken fillets coated by gelatin-carboxymethyl cellulose (cmc) film containing essential oil (eo) of bene (pistacia atlantica). methods: the chicken fillets were coated by gelatin-cmc film co...

An integrated system of two-stage microbial fuel cells (MFCs) and immobilized biological aerated filters (I-BAFs) was used to treat palm oil mill effluent (POME) at laboratory scale. By replacing the conventional two-stage up-flow anaerobic sludge blanket (UASB) with a newly proposed upflow membrane-less microbial fuel cell (UML-MFC) in the integrated system, significant improvements on NH(3)-N...

Kinneyia are a class of microbially mediated sedimentary fossils. Characterized by clearly defined ripple structures, Kinneyia are generally found in areas that were formally littoral habitats and covered by microbial mats. To date, there has been no conclusive explanation of the processes involved in the formation of these fossils. Microbial mats behave like viscoelastic fluids. We propose tha...

the effect of enzymatic treatment time of microbial transglutaminase (mtgase) on the characteristics of whey protein isolate (wpi) films was investigated. results shown that the properties of mtgase-treated films were affected by increasing the enzymatic treatment time. enzymatic treatment at lower incubation time, i.e. for 1 h, significantly resulted in higher values of tensile strength (ts) a...

the main objective of this study was to produce ldpe active films containing metallic nanoparticles (ag, zno and cuo) and to investigate their physical, mechanical and anti-microbial characteristics. three types of metallic nanoparticles at concentrations of 1% (w/w) were added to low density polyethylene (ldpe) and the films were prepared using melt extrusion technique. sem results indicated r...

Microbial mass can be said to occur in one of two states; as 'flocs' frcely suspended in an aqueous medium, or as a 'film' adhering to a support surface. Industrial fermenter configurations, at least since the development of deep-tank fermentation, have almost invariably been based on the use of microbial flocs, and the occurrence of a visible microbial film during fermentation is generally avo...

The effects of poly(lactic acid) (PLA)-based film with inorganic antimicrobial nano-TiO₂ and nano-Ag on the physicochemical and microbial quality of Tremella aurantialba stored at 4 ± 1 °C for 16 days was investigated. Rosemary essential oil (REO, 9 wt %) was added into PLA film as plasticizer. Low-density polyethylene (LDPE) and PLA film was used as the controls. The experiment measured physic...

Research was conducted in a certified organic apple (Malus x domestica Borkh.) orchard in 2000 to determine the effect of organic pest management techniques on pest control, apple yields and microbial populations on harvested apples. In Experiment I, apple colouring bags, sticky red spheres, kaolin particle film, kaolin particle film plus sticky red spheres, or colouring bags plus sticky red sp...
