Effects of Lysinibacillus sphaericus on Physicomechanical and Chemical Performance of OPC Blended with Natural Tuff and Pulverized Fly Ash

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022
This paper reports study findings on the use of Lysinibacillus sphaericus (at 1.0 × 107 cells/ml concentration) to enhance and improve the physicomechanical and chemical properties of blended Ordinary Portland Cement (OPC). Blending was done separately with pulverized fly ash (PFA) and natural pozzolana (volcanic tuff) at substitution levels of 10%, 20%

Increasing the Bioavailability of Phosphate by Using Microorganisms

International Journal of Agronomy, Volume 2022, Issue 1, 2022., 2022
Phosphorous (P) is a nonrenewable and one of the most important macronutrients for all living organisms. The formation of complexes with cations such as Al, Fe, and Ca reduces the solubility of P leading to limiting the absorption of P by plants. Therefore, we need to apply excessive amounts of P through conventional fertilizers.

The mechanism of thiosulfate oxidation by Thiobacillus thiooxidans 8085

, 1999
Growth of Thiobacillus thiooxidans 8085 on 9K medium containing thiosulfate instead of sulfur, as the sole energy source, was successfully attained. The optimum growth pH was maintained at 5.0 during cultivation. The cultivation period for T. thiooxidans on thiosulfate was 4-5 days at 28$\sp{\circ}$C.
