Complexation of Uranium by Cells and S-Layer Sheets of Bacillus sphaericus JG-A12

2005

ABSTRACT Bacillus sphaericus JG-A12 is a natural isolate recovered from a uranium mining waste pile near the town of Johanngeorgenstadt in Saxony, Germany. The cells of this strain are enveloped by a highly ordered crystalline proteinaceous surface layer (S-layer) possessing an ability to bind uranium and other heavy metals. Purified and recrystallized S-layer proteins were shown to be phosphorylated by phosphoprotein-specific staining, inductive coupled plasma mass spectrometry analysis, and a colorimetric method. We used extended X-ray absorption fine-structure (EXAFS) spectroscopy to determine the structural parameters of the uranium complexes formed by purified and recrystallized S-laye…

Hydrolytic enzyme activity of Paenibacillus sp. strain B2 and effects of the antagonistic bacterium on cell integrity of two soil-borne pathogenic fu…

2000

Paenibacillus sp. strain B2, isolated from the mycorrhizosphere of Sorghum bicolor and having an antagonistic activity towards soil-borne fungal pathogens, possessed extracellular cellulolytic, proteolytic, chitinolytic and pectinolytic enzyme activities. The eventual role of these lytic enzymes in cellular interactions between Paenibacillus sp. strain B2 and Phytophthora parasitica and Fusariumoxysporum was investigated by electron microscopy and molecular cytology. Electron microscopic observations showed that the presence of Paenibacillus sp. strain B2 resulted in disorganisation of cell walls and/or cell contents of P. parasitica and F. oxysporum. However, when P. parasitica was treated…

Działanie pelargoniowego olejku eterycznego na Bacillus spp.

2018

Pelargonia pachnąca (Pelargonium graveolens) jest aromatycznym krzewem posiadającym jasnozielone, owłosione, miękkie w dotyku, karbowane liście i małe, różowe kwiaty. Należy do rodzaju Pelargonium (Geraniaceae) i liczy ponad 250 gatunków. Olejek eteryczny pozyskiwany z pelargonii jest bardzo ceniony nie tylko przez przemysł perfumeryjny czy aromaterapię, ale także przez przemysł spożywczy, kosmetyczny jak i farmację. Roczną produkcję olejku szacuje się na 300 ton. Liczne badania wskazują na jego silne właściwości przeciwbakteryjne, przeciwwirusowe, przeciwbólowe czy przeciwzapalne. Celem przeprowadzonych badań było określenie aktywności olejku pelargoniowego wobec Bacillus spp. Zebrano jedn…
