Interactions between inhibition factors on microbial stability of fruit-based systems

Abstract

Measurement of metabolic CO2 by head space gas chromatography was used in the preparation of shelf-life maps of fruit-based systems. The systems analysed, all of which were peach-based, differed with respect to aw (0.995, 0.934 and 0.890), pH (3.02, 3.60 and 4.09) and benzoic acid concentration (0, 100 and 200 ppm). The test microorganism was a strain of Saccharomyces cerevisiae isolated from spoiled soft-drinks and chosen for its characteristic of multiple resistance. Three different thermal treatments were applied (54 degrees C for 15 min, 58 degrees C for 8 min, 63 degrees C for 3 min) to the systems and their effectiveness was evaluated in relation to the untreated controls. In contrast with observations for osmotolerant species, the relative preservative effectiveness on the test strain decreased with reducing aw and showed only a slight synergistic action with thermal treatment. Besides, the aw of the systems interacted synergistically with the thermal treatment effectiveness in a manner differing from that described for osmotolerant species.

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.
