Four enzymes were separated from an extracellular preparation of Bacillus polymyxa by carboxymethylcellulose column chromatography. The pH optima were 8.3 to 8.5, 8.7 to 8.9, 9.2 to 9.4, and 9.5 to 9.6. All of the enzymes required calcium ion for maximum activity, whereas strontium ion was only partially effective in stimulating activity. Cobalt was the only other cation tested which was effect...

We used corn seeds from maize (Zea mays L.) of the Dnieper 196 SV hybrid to analyze pre-sowing seed bacterization and treatment with biogenic silicon that could be promising in growing hybrids. The chlorophyll content leaves plants gradually increased growth phases reached its maximum phase milky ripeness grain under presowing Paenibacillus polymyxa KB Biogenic Silicon (BSi). yield during both ...
