The aim of the work was selection cultures Bacillus spp. and Lactobacillus promising for use as probiotics. Samples chicken droppings (250 samples) research were collected in period 2020 from clinically healthy chickens (age 28-48 days). poultry farms various scales methods keeping (large-scale industrial farms, homestead farms) Vinnytsia, Zhytomyr, Kyiv, Kharkiv, Cherkasy, Chernihiv regions. A...

The biological effects of ribonucleases (RNases), such as the control of the blood vessels growth, the toxicity towards tumour cells and antiviral activity, require a detailed explanation. One of the most intriguing properties of RNases which can contribute to their biological effects is the ability to form dimers, which facilitates efficient RNA hydrolysis and the evasion of ribonuclease inhib...

Gram positive aerobic or facultatively anaerobic spore forming gram positive bacilli were first identified by Christian Gottfried Ehrenberg in 1885 and were later classified by Ferdinand Cohn in to a separate genus Bacillus [1]. Aerobic spore forming gram positive bacteria are commonly referred to as ASB’s and includes members of Bacillus spp which are basically saprophytes living as thermophil...

A biocathode was designed by the modification of a carbon nanotube (CNT) gas-diffusion electrode with bilirubin oxidase from Bacillus pumilus, achieving high current densities up to 3 mA cm(-2) for the reduction of O2 from air. A membraneless air-breathing hydrogen biofuel cell was designed by combination of this cathode with a functionalized CNT-based hydrogenase anode.

The antibacterial activity of Bulbophyllum neilgherrense was tested against five species of bacteria, viz., Escherichia coli, Staphylococcus aureus, Bacillus pumilus, Pseudomonas aeruginosa and Pseudomonas putida Aqueous, ethanolic and chloroform soluble extracts of leaf and pseudobulb (5.50 w/v) were screened for their antibacterial potential. The zone of inhibition was seen to be largest when...
