γ-PGA (Gamma-poly-glutamic acid)

by Master, posted in γ-PGA

γ-PGA (Gamma-poly-glutamic acid) is a natural occurring, multi-functional, and biodegradable biopolymer. It is produced through fermentation by Bacillus subtilis using glutamic acid.

PGA is consists of glutamic acid monomers crosslinked between α-amino and γ-carboxyl groups, and the molecular weight of PGA is usually between 100~1000 kDa.

It is water-soluble, edible and non-toxic towards human, and is environment friendly. It has broad applications in the fields of medicine, food, cosmetics, and water treatment.

Bacillus subtilis can improve soil structure, widely used in bacterial fertilizer

by Master, posted in Bacillus subtilis

Bacillus subtilis forms a probiotic environment in the soil, promotes the formation of agglomerates, improves soil fertility and water retention, increases soil porosity, and promotes root growth. Specifically, it accelerates the mineralization of nutrients and changes nutrients from ineffective and slow-acting states to effective and fast-acting states. At the same time, it accelerates the humification of nutrients, secretes phytase, degrades most of the phytate in the soil; produces auxin, stimulates the growth of crops, and improves the survival rate and emergence rate of seeds.

Bacillus subtilis is widely used in biological fertilizers. When applied to crops or soil, it can colonize in the rhizosphere or in vivo of crops, and has a specific fertilizer effect.

Bacillus subtilis can induce plant resistance

by Master, posted in Uncategorized

Bacillus subtilis can directly inhibit plant pathogens, and enhance the disease resistance of plants by inducing their own disease resistance potential.

For example, Bacillus subtilis, a biocontrol bacterium against rice sheath blight, can induce the activity of enzymes (POD, PPO and SOD) related to disease resistance in rice sheath cells to increase, and achieve disease resistance.

Bacillus subtilis can boost immunity and promote growth

by Master, posted in Uncategorized

Bacillus subtilis can secrete active substances, activate the plant defense system, enhance the immunity and disease resistance of crops, and reduce or eliminate the damage of pathogenic bacteria to plants.

It can also promote the growth and development of a variety of plant seeds, seedlings and roots, and enhance the disease resistance of plants, thereby indirectly reducing the occurrence of diseases. Such as increase the formation of auxins such as indole acetic acid, stimulate crop root development, and enhance photosynthesis. At the same time, it converts the substances that are difficult to absorb in the soil into substances that are easy to be absorbed by crops, promotes the absorption and utilization of nutrients by crops, and improves the utilization rate of fertilizers.

Bacillus subtilis can produce antibacterial substances

by Master, posted in Uncategorized

Bacillus subtilis can produce a variety of substances with bacteriostatic and bacteriolytic effects during the growth process, such as subtilisin, organic acids, antibacterial proteins, etc.

These substances can inhibit the growth and reproduction of pathogenic bacteria, and even destroy the bacterial structure and kill pathogenic bacteria.

Therefore, Bacillus subtilis has a good effect on the control of soil diseases such as stubble and root rot.

Competition for nutritional and spatial sites of Bacillus subtilis

by Master, posted in Bacillus subtilis

The competition of Bacillus subtilis mainly includes nutrient competition and spatial site competition. It can multiply and colonize rapidly and in large quantities in the rhizosphere, body surface or body of plants and in the soil, effectively repelling, preventing and interfering with the colonization and infection of plant pathogenic microorganisms on plants, so as to achieve the effect of bacteriostasis and disease prevention .

Bacillus subtilis against has excellent control effect against rice blast, powdery mildew & gray mold of Watermelon, cucumber, strawberry, tomato and other crops, potato late blight, soybean, rape sclerotinia, root rot and other fungal diseases of crops such as melons, cereals and Panax notoginseng.
