Effects of gamma irradiation and storage time on the Chemical and Sensory quality of ostrich meat stored at 4 ̊C were evaluated in this study. Irradiation increased (P<0.05) the intensity of lipid oxidation, irradiation odor and loss of color and sensory quality in aerobic packages. No significant differences in pH value of ostrich meat were observed due to irradiation. Considering the sensory a...

--We assayed restriction-site differences in mitochondrial DNA (mtDNA) within and among populations of the Ostrich (Struthio camelus) throughout much of its African distribution. Little genetic diversity was evident among samples drawn from localities throughout southern Africa (S.c. australis), while deep divisions in the mtDNA gene tree exist between representatives of the eastern (S.c. molyb...

Clostridium difficileisa binding warm-positive rod and anaerobic organism, which was first described in 1935 as Bacillus difficile. Epidemiology of CDI has changed considerably on 2000. Occurrence and severity of the disease  including ulcerative colitis(inflammation of the colon), colectomy(colon section) and mortality had increased. Recent studies have reported Clostridium difficile prevalenc...

Oxygen (O2) consumption and carbon dioxide (CO2) excretion of ostrich embryos were studied on 45 ostrich eggs in various stages of development. A closed respirometry system was used for eggs subjected to ≤ 10 days of incubation, while an open flow system was used for older eggs. A total of 102 measurements were made and repeat measurements on the same egg were treated as independent during stat...

________________________________________________________________________________ Abstract The objective was to determine the growth responses of Black Neck ostrich chicks to different dietary levels of L-carnitine in pre-starter diets. Thirty-two day-old ostrich chicks were randomly divided into four treatments with four replicates, each containing two chicks. All birds received the same basal ...

The complete mitochondrial DNA (mtDNA) molecule of the ostrich, Struthio camelus, was sequenced. The size of the molecule is 16,591 nucleotides. Since the ostrich represents the paleognathous birds, comparison with the mtDNA of the neognathous chicken, the only avian species reported so far in databases, made it possible to identify common and, probably, general avian mtDNA characteristics. Rel...

Municipal compost sample was pyrolyzed to produce compost char as a sorbent for removing the herbicide atrazine from solution. The compost-based char was compared with an activated carbon derived from corn stillage. When compost was pyrolyzed, the char yield was greater than 45% when heated under air, and 52% when heated under N2. In contrast, when the corn stillage was pyrolyzed under N2, the ...

This review critically examines char conversion kinetics in oxidizing or reducing atmosphere. In kinetic analysis the devolatilization of biomass and the conversion of char are usually investigated by means of separate experiments, although some kinetic models are also available of biomass combustion. The large majority of the char conversion kinetics consists of a global reaction with activati...
