Summary
Calcium enrichment in edible mushrooms enhances their health benefits and nutritional value. Moderate calcium levels boost mushroom growth and beneficial metabolites, making them a valuable food source.
Area of Science:
- Food Science
- Mycology
- Nutritional Biochemistry
Background:
- Calcium is vital for biological functions like blood pressure regulation and bone health.
- Edible mushrooms can be cultivated to be rich sources of calcium.
- Calcium enrichment converts inorganic calcium into organic metabolites within mushrooms.
Purpose of the Study:
- To review the impact of calcium enrichment on edible mushroom growth and metabolites.
- To elucidate the mechanisms behind calcium accumulation in mushrooms.
- To guide the cultivation of mushrooms with enhanced biological activities and calcium content.
Main Methods:
- Literature review of studies on calcium-enriched edible mushrooms.
- Analysis of calcium sources (CaCO3, CaCl2, Ca(NO3)2) used in cultivation.
- Examination of effects of varying calcium levels on mushroom growth and metabolite production.
Main Results:
- Low calcium levels generally promote edible mushroom production.
- High calcium concentrations can inhibit mushroom growth.
- Moderate calcium enrichment enhances key metabolites like phenolics, flavonoids, and polysaccharides.
Conclusions:
- Calcium enrichment is a viable strategy to improve the nutritional and biological value of edible mushrooms.
- Understanding calcium uptake mechanisms allows for optimized cultivation for health benefits.
- Calcium-enriched mushrooms offer significant potential for the food industry.

01:27Feedback Regulation of Calcium Concentration
3.4K
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

4.6K
Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Basidiomycota is a diverse phylum of fungi that includes ecologically significant decomposers such as white rot fungi, symbionts like mycorrhizal fungi, plant pathogens such as rusts and smuts, and edible species like Agaricus bisporus (the common button mushroom). These fungi play crucial roles in nutrient cycling, symbiotic relationships, and even human health. Their defining feature is the basidium, a microscopic club-shaped structure responsible for producing basidiospores.Fruiting Bodies...
