Abstract

For the screening of bioactive compounds and study of global distribution, a selective isolation method for Planomonospora strains by centrifugation from soil is examined. Planomonospora strains produced characteristic sporangia on the humic acid-trace salts gellan gum medium (pH 9.0) so that this genus was readily recognized on the isolation plate. High yields of motile spores were obtained by using a flooding solution containing 0.1% skim milk in 5 mM N-cyclohexyl-2-amino-ethanesulfonic acid (pH 9.0) followed by incubating the preparation at 32 degreesC for 90 min, centrifuging it at 1000 x g for 10 min, and further incubation at 32 degreesC for 60 min after centrifugation. By combining the techniques described above, we isolated 246 Planomonospora strains from 137 of the 1200 soil samples examined. Ninety-four percent of these strains were recovered from neutral to slightly alkaline soils (pH 7.0 to 9.0). Strains of P. venezuelensis group were obtained from 13 soil samples (1.1%), which were collected in Bolivia, Cyprus, Egypt, Greece, India, Japan, New Caledonia, and Turkey. Strains of this group appear widely distributed in the soil of tropical to temperate regions. To our knowledge, this is the first record that strains o...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.
