Hydrogels are introduced to modem medicine as novel materials suitable for a variety ofbiomedical applications. Studying hydrogels as novel biomaterials has become a fast-developingand exciting research field during the last two decades. These interesting biomaterials have found awide range of application including contact lenses, vehicles for drug delivery and scaffold in tissueengineering and...

Little is known on physicochemical and biochemical characteristics of "Pecorino" Abruzzese cheese in L'Aquila province, an artisanal cheese produced from ewe raw full-cream milk. Three batches of inland "Pecorino" Abruzzese cheese were examined for microbiological, compositional, biochemical and sensory characteristics at the aim of isolating and storing in a bacterial collection, indigenous st...

This work evaluated the microbiological and physicochemical quality of Minas Frescal cheese sanitized with ozonated water at concentration of 2 mg.L-1 for 1 or 2 minutes. No counts of Enterobacteriaceae, Staphylococcus sp. and total and thermotolerants coliforms were found in the samples. Additionally, significant microbial reductions were observed for ozonated samples and the lowest counts wer...

The present study aimed to characterize five commercial honeys available in the Portuguese market in respect to their floral origins, physicochemical parameters and microbial safety and commercial quality assessment. Pollen profile, colour, moisture content, ash, acidity, electrical conductivity, pH, reducing sugars, apparent sucrose and HMF were the parameters analysed in each honey sample. Ae...

Microbial sulfate reduction (SR) is a dominant process of organic matter mineralization in sulfate-rich anoxic environments at neutral pH. Recent studies have demonstrated SR in low pH environments, but investigations on the microbial activity at variable pH and CO2 partial pressure are still lacking. In this study, the effect of pH and pCO2 on microbial activity was investigated by incubation ...

Thermal characteristics of egg white proteins (EWP) may differ in the presence of saccharides. Therefore, the influence of saccharides including carboxymethyl cellulose (CMC), pectin, sucrose and maltodextrin and heating time on physicochemical characteristics of EWP as a whole were studied. Investigation of Heat Coagulation Time (HCT), solubility, turbidity and protein secondary structure of h...

This work was designed to determine the effect of poultry droppings on diesel contaminated soil and evaluate its physiochemical properties. In this study, different ratios of diesel contaminated soil and poultry droppings have been used as raw materials. The mixture of diesel contaminated soil and poultry droppings were allowed to composting process for 40 days. The physicochemical parameters l...
