Surface mycobiota on Argentinean dry fermented sausages

International Journal of Food Microbiology

Abstract

The diversity of the mycobiota community occurring on the surface of fermented dry sausages and in the environment of the processing plants was studied. The manufacturing plants (five in total) were located in three different areas of southern Buenos Aires province (Argentina). Samples were collected from two types of fermented sausages (short and long ripening time) at two times of the year (winter and summer) and at different types of plants (artisanal and industrial). A total of 342 samples were examined and 822 isolates belonging to six genera and 16 fungal species were identified. In most cases, Penicillium was the genus most frequently isolated. Penicillium nalgiovense, P. nordicum, P. solitum and P. chrysogenum were the most abundant species. The characteristics of the plants and the season were the influencing factors on the composition of the mycobiota. Under conditions of high humidity and in ripening rooms with reduced ventilation, Mucor racemosus was most prevalent. Eurotium amstelodami and Aspergillus spp were detected mainly during the summer when the temperature was higher. A high number of species isolated from the surface of the sausage was also isolated from air samples. Geotrichum candidum, Alternaria infecto...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
