General description
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.[1] 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.[2]
Application
- 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).
