Abstract

Four species of bifidobacteria were evaluated for growth, viability, and proteolytic activity in whole camel milk, and comparison was made with whole cow milk. Growth of all species in either whole milk was characterized by the appearance of two logarithmic phases following anaerobic incubation at 37 degrees C for 36 h. The growth rate of Bifidobacterium longum 15,707 was higher in camel milk than in bovine milk and was higher for Bifidobacterium angulatum 27,535 in bovine milk than in camel milk. Bifidobacterium bifidum 2715 and Bifidobacterium breve 2258 showed the same trend as B. angulatum 27,535 after 16 h of postinoculation. Viable counts of all species except B. bifidum 2715 increased in the fermented whole milks during the first 3 d of storage at 4 degrees C. However, such counts did not change in unfermented milk, except for B. longum 15,707, which showed an increase in viable counts after 12 d of storage. Viability of all species in both fermented and unfermented milks was unaffected during refrigerated storage for 15 d. All species except B. longum 15,707 showed higher proteolytic activity in fermented camel milk than in bovine milk. However, proteolytic activity of all species except B. breve 2258 started at d 9 in ...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.
