Descrizione

Descrizione generale

Magnesium sulfate heptahydrate is the hydrated salt of magnesium. The spin-Hamiltonian parameters of the (Cu(H₂O)₆)²⁺ complex in magnesium sulfate heptahydrate have been determined by electron spin resonance (ESR) spectral studies. Raman spectra of 10 hydrated and anhydrous forms of magnesium sulfates have been reported. Their crystal structure and space groups have been evaluated by Raman and XRD (X-ray diffraction) studies.

Applicazioni

• Optimization of the fermentation media and growth conditions of Bacillus velezensis BHZ-29: This research utilizes Magnesium sulfate heptahydrate as a crucial micronutrient in the optimized growth medium for Bacillus velezensis, enhancing its bioactivity and efficacy in agricultural biocontrol applications (Shi et al., 2024).


• Research on and Model Analysis of Flexural Mechanical Properties of Basic Magnesium Sulfate Cement Concrete Beams: The study focuses on the use of Magnesium sulfate heptahydrate in the production of magnesium sulfate cement, a material noted for its improved flexural strength and durability, which is critical for sustainable construction practices (Mei et al., 2024).


• Antimicrobial Activity of Bacillus amyloliquefaciens BS4 against Gram-Negative Pathogenic Bacteria: Magnesium sulfate heptahydrate is used here as a component of the growth medium to enhance the production of antimicrobial compounds, illustrating its role in supporting microbial activity with potential applications in biotechnology and pharmaceuticals (Palacios-Rodriguez et al., 2024).
