Oxytetracycline which is derived from Streptomyces rimosus, inhibits a wide range of bacteria and is industrially important. The underlying biosynthetic processes are complex and hinder rational engineering, so industrial manufacturing currently relies on classical mutants for production. While the biochemistry...
After performing the second filtration with a cell strainer, the single-cell suspension was stained with fluorescein diacetate (FDA) at 14 mM final concentration for 3 min on ice and the number and activity of cells was calculated with microscope (ZEISS Axioscope A1). The protoplasts with a...
Mountains are among the most sensitive ecosystems to climate change, and one of the most evident signs of climate-related effect is the continuous net loss
As confirmed by microscopic inspection (Supplementary Fig. 1a, b), S. venezuelae initiates differentiation after ca. 12–14 h of growth when grown in liquid MYM medium, which is mainly marked by fragmentation of vegetative hyphae. After ca. 16–18 h of incubation, spores begin to be ...
installation for preparing a slurry filtration process is mainly by example, and to operate the facility.in this installation comprising a device (1) for a unit load of mud, (3) drying the mud flow, a separator (4,5), a thermal treatment chamber (7).a hot gas cyclone (8), and a ...
The removal of carbon dioxide from the atmosphere by the marine biological pump is a key regulator of Earth’s climate; however, the ocean also serves as a large source of nitrous oxide, a potent greenhouse gas and ozone-depleting substance. Although bio
Experimental evidence has shown that graphene oxide (GO) can be impermeable to liquids, vapors and gases, while it allows a fast permeation of water molecules. Theoretical studies to understand the filtration mechanisms come mostly from water desalination, while very few works have been dedicated to...
Raw, half-refined or refined vegetable oil is used for the production. In the case of using raw or half-refined vegetable oil, it must first undergo a pre-treatment process that consists of degumming and neutralization. Degumming has purpose to remove gummy substances mainly on the basis of ...

Progression from adenoma to invasive carcinoma requires accumulation of mutations starting with the Adenomatous Polyposis Coli (Apc) gene. NF-κB signalling is a key element in cancer, mainly related to the activity of IKKβ. IKKα kinase also participates in this process by mechanisms that are ...
