Background: Malga cheeses are made in artisanal and seasonal dairies located in the Alps. This study was carried out to determine microbial diversity and sensorial properties of Malga cheese from Trentino (Italy) after long-term ageing period. The effects of adding the Fermalga Bacterial Pools (FBP) on microbiota biodiversity of cheese were also evaluated. Methods: Populations of Lactic Acid B...
To investigate the possibility to carry pathogen bacteria in turkey flocks via cryopreserved semen, research was carried out 1) to investigate the microbial contamination of fresh and frozen thawed turkey semen and 2) to evaluate the effect of the freezing-thawing process on the survival of 3 serovars of Salmonella spp. experimentally inoculated in turkey semen. Five pools of semen diluted 4-fo...
For decades, microorganisms in beet sugar production have been studied using culture-based methods. However, these methods are not sufficient to describe such a complex bacterial community. In this study, therefore, an amplicon-based sequencing technique (Illumina MiSeq platform) was applied characterize the community and its dynamics extraction area juice purification station of Austrian plant...
To contribute to the identification of methanogens, methanotrophs and sulfate-reducing bacteria (SRB) in microbial communities from the 13 degrees N (East Pacific Rise) and Rainbow (Mid-Atlantic Ridge) hydrothermal vent fields, we investigated the diversity of mcrA, pmoA and dsrAB genes sequences. Clone libraries were obtained using DNA isolated from fragments of diffuse vents, sediment and in ...
Ubiquitous bacteria from the genus Oleispira drive oil degradation in the largest environment on Earth, the cold and deep sea. Here we report the genome sequence of Oleispira antarctica and show that compared with Alcanivorax borkumensis--the paradigm of mesophilic hydrocarbonoclastic bacteria--O. antarctica has a larger genome that has witnessed massive gene-transfer events. We identify an arr...
In this study, the effects of grape seed flour on the physical-chemical properties, microbiological and sensory properties of Turkish dry fermented sausage, sucuk, was investigated. After the sausages produced with beef, beef fat, sheep tail fat and spices, they were ripened for 14 d. Then they were vacuum-packaged and stored for 80 d at 4℃. The effects of grape seed flour (GSF; 0%, 0.75%, 1.5%...
Seventy polyfloral honeys including commercial samples obtained from supermarkets, harvested from apiaries and purchased in bulk were initially examined for total antibacterial activity. From each sample, numbers of aerobic mesophilic bacteria, total coliforms, moulds and yeasts were determined and the presence of Salmonella spp., Shigella spp., Clostridium sulfite-reducers, Paenibacillus larva...
Mozzarella cheese can be considered by far the world’s most popular Italian dairy product. Extending shelf life of mozzarella is an important issue in industry due to high risk contamination several bacteria species, including spoilage pseudomonads. In this work, active packaging was prepared coating traditional polyethylene terephthalate (PET) containers “ovoline” with a food-grade resin mixed...
