Photosynthetic bacteria: a natural gift of a 'live fertilizer factory'

——How ancient microorganisms reshape modern agriculture and ecology

? The 'living fossil' of the origin of life

      Photosynthetic bacteria (PSB) are one of the oldest microorganisms on Earth, existing in ancient atmospheres filled with methane and hydrogen sulfide. They have a "dual survival system": they can use light energy for photosynthesis in anaerobic environments, as well as decompose organic matter under aerobic dark conditions. This unique metabolic ability makes it a "geochemical engine" driving the carbon, nitrogen, and sulfur cycles.   

      One gram of soil can contain hundreds of millions of photosynthetic bacteria, which naturally inhabit paddy fields, swamps, lakes, and maintain ecological balance by degrading substances such as sulfides and ammonia. Its bacterial cells are rich in 60% -65% high-quality protein, B vitamins, coenzyme Q10 and other active substances, serving as both a "nutrient bank" for plants and an "antidote" for soil.

?  The Quartet of Agricultural Revolution

1. Green engine for increasing production and improving quality

      Root explosiveness: secretes hormones such as indole-3-acetic acid and cytokinins to stimulate root growth. The experiment showed that the use of photosynthetic bacteria increased the root weight of sweet potatoes by 79% and the number of soybean nodules by 38%.   

      Photosynthetic Accelerator: After foliar spraying, the microbial community accumulates CO ₂ on the plant surface, increasing soybean chlorophyll content by 25.8%, rice yield by 10.48%, and melon sugar content by 1-10 points.   

      Extreme case: Millet growers in Ruicheng, Shanxi Province discovered that after spraying the microbial agent, the ears appeared 2 days earlier, the ears were full and resistant to lodging, and the income increased by 200 yuan per mu.

2. Microbial Corps for Soil Remediation

Photosynthetic bacteria can reconstruct soil microecology:

      Probiotic amplification: The number of nitrogen fixing bacteria and rhizobia increases by 50% -100%, forming a "symbiotic fortress".   

      Inhibition of harmful bacteria: Reduction of filamentous fungi by 60% -85%, preventing and controlling soil borne diseases from the root.   

      Saline alkali land reversal: Decomposing phytic acid salts releases phosphorus and potassium, increasing the efficiency of saline alkali land restoration by 40% and significantly improving soil particle structure.

3. Natural vaccines for plant immunity

      Disease resistance: Inducing plants to develop systemic resistance, delaying the onset of tobacco mosaic virus by 2 days, and reducing dry matter loss caused by the disease by 85%.   

      Resilience: Spraying microbial agents and brown sugar can resist the cold of late spring; Maintain crop vitality under drought and salt stress.

4. The 'cleaner' of the ecological chain

      Straw returning savior: Applying 5-7.5 liters of bacterial solution per hectare on rice straw returning plots can neutralize the organic acids produced by decomposition and solve the problem of "root burning".   

      Heavy metal sniper: In the Chongzhou experiment in Sichuan, the cadmium content in rice decreased from 0.33mg/kg to 0.05mg/kg, a decrease of 85%.

?  The 'invisible guardian' of aquaculture

      Water purification: Absorb ammonia nitrogen and nitrite to solve the problem of algae deposition in ponds. The case shows that after spraying bacterial solution for 2 days, nitrite decreased from 0.15mg/L to the safe value.   

      Fish fry guardian: After the use of Lingbao fish pond in Henan, the hatching survival rate of fish fry jumped from 20% to 50%, and the sediment at the bottom of the pond decreased by 90%.   

      Ecological bait: The bacterial protein content exceeds 60%, making it a high-quality natural feed for filter feeding fish.

method

      Seed mixing: Soak the seeds in a 200 fold dilution solution for 4-8 hours (6 hours for cucumber and 4 hours for chili).   

      Spraying: Spray 200-300 times the liquid on the leaves, operate on cloudy days or in the evening, avoid UV inactivation.   

      Root irrigation: During the planting period, irrigate with 150 times the amount of liquid, 10ml per plant, to prevent and control bacterial wilt.   

>Taboo:

>Avoid mixing with copper agents, streptomycin, and alkaline pesticides

>The initial use effect of the disease is better than that during the outbreak period

>If it rains within 4 hours, it needs to be sprayed again

Data Express:

|Crop | Usage | Yield Increase | Quality Improvement|

|--------|------------|----------|------------------------|  

|Sweet potato | Spraying throughout the entire growth period | 78.6% | Starch content increased by 0.3%|

|Cucumber | Planting and root irrigation | 33% | Extended storage period by 5 days|

|Rice | Spraying during tillering stage | 10.48% | Cadmium residue ↓ 85%|

|Fish pond | Monthly sprinkling | -- | Fish fry survival rate increases by 150%|

?  Future Outlook: Ecological Link from Farmland to Planet

      The Xinjiang Academy of Agricultural Sciences has established the world's largest library of photosynthetic bacteria strains (containing 1532 strains, including 25 new species from around the world), which is promoting the technology of manure resource utilization - converting livestock and poultry wastewater into microbial fertilizers, achieving a "planting and breeding cycle". With the development of genomics, strains such as KC14-1 with multiple disease resistance genes will unlock the potential for integrated applications of "nitrogen fixation disease suppression repair".
