Evaluation of autochthonous subsp. strain as a candidate starter culture in white-brined cheese.

Unlabelled: subsp. NCCB100539 isolated from an artisanal raw ewe's milk cheese was evaluated as a potential starter culture in white-brined cheese. As a safety criteria, the cytotoxicity of the viable and heat-killed cells and CFE of this strain were determined on Caco-2 cell line by MTT assay.

Effects of high hydrostatic pressure on antimicrobial protein stability and the rheological and shelf-life properties of donkey milk.

The effects of high hydrostatic pressure (HHP) and heat treatments on antimicrobial protein stability and on the physico-chemical, microbiological, rheological and shelf-life properties of donkey milk were investigated. Although heat treatment at 75°C for 2 min resulted in 1.50 log CFU ml microbial inactivation, losses in activities of lysozyme (58%) and lactoferrin (82%) were observed due to whey protein denaturation.

Use of yeast isolates of cheese origin as adjunct culture in Beyaz cheese: Influence on sensorial, textural and quality characteristics.

Unlabelled: The effects of various yeast species isolated from raw-milk cheese were evaluated in Beyaz cheese. Four batches of cheeses were produced, in which the control cheese involved only commercial starter culture while YL, DH and KL cheeses were produced with the incorporation of individual and , respectively. The chemical composition, microbial counts, sensory attributes, volatile compounds and textural properties of cheeses were determined on days 1, 30, and 60 during the ripening period.

Use of kefir and buttermilk to produce an innovative quark cheese.

Quark cheese is a fermented soft fresh cheese categorised under acid-rennet coagulated cheeses. In this study, alternative raw materials such as kefir and yayik buttermilk were used to produce Quark cheese in comparison with the cheese produced by the acidification of skim milk with mesophilic lactic culture. Samples were kept individually under 35 °C and 100 °C for coagulum formation.

Effect of inulin polymerization degree on various properties of synbiotic fermented milk including Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12.

The effects of inulin degree of polymerization (DP) on the viabilities of Lactobacillus acidophilus La-5 and Bifidobacterium animalis Bb-12 and on some parameters of fermented milk, such as microbiological, rheological, biochemical, and sensory properties, were investigated during 30 d of storage. Samples were produced using L. acidophilus La-5 and B.

Protease and lipase activities of fungal and bacterial strains derived from an artisanal raw ewe's milk cheese.

We previously identified the microbiota present during cheese ripening and observed high protease and lipase activity in Divle Cave cheese. To determine the contribution of individual isolates to enzyme activities, we investigated a range of species representing this microbiota for their proteolytic and lipolytic ability. In total, 17 fungal, 5 yeast and 18 bacterial strains, previously isolated from Divle Cave cheese, were assessed.

A genomic survey of proteases in Aspergilli.

Background: Proteases can hydrolyze peptides in aqueous environments. This property has made proteases the most important industrial enzymes by taking up about 60% of the total enzyme market. Microorganisms are the main sources for industrial protease production due to their high yield and a wide range of biochemical properties.
