Acetobacter is an obligatory aerobic, nitrogen-fixing bacteria. It can fix atmospheric nitrogen in the roots, stems, and leaves of sugar-producing crops like sugarcane, sweet potatoes, and others. It is an acid-producing microbe. It produces growth hormones such as Indole Acetic Acid (IAA) and Gibberellic acid, which promote root proliferation and increase the number of rootlets, resulting in phosphate solubilisation and mineral and water uptake. All of these promote cane growth and sugar recovery in the cane.

Acetobacter can fix a considerable quantity of nitrogen in the range of 10–15 kg N/acre in soil and reduce the use of nitrogen fertiliser by up to 25%. It also converts non-available forms of micronutrients into available forms and increases the crop yield by 10–12%.

Benefits of Acetobacter Biofertilizer

  • The formulation improves crop germination, early emergence, and root development by increasing nitrogen availability for the plant.
  • It increases yield and quality by 10–12%.
  • It improves the physical and chemical properties of soil with aeration and water retention.

Mechanism of Action

Acetobacter has a symbiotic relationship with a variety of plants, including sugarcane and coffee. It colonises their internal tissues and promotes plant growth by producing growth hormones and by converting inorganic nutrients into organic form. All the nitrogen-fixing bacteria contain an enzyme called the nitrogenase enzyme. The nitrogenase enzyme catalyses the ATP-dependent reduction of N2 to NH3 (ammonia). Acetobacter fixes nitrogen under aerobic conditions. It requires oxygen to produce the large amounts of ATP required for
nitrogen fixation.

Target Crops of Acetobacter

Sugarcane, Sweet Potato, Cassava etc.

Application of Acetobacter

  • Soil application: Mix 2.0 litres of Acetobacter biofertilizer formulation with 50 kg of well decomposed organic manure/FYM/vermicompost. Keep the mixture under shade for one week and then broadcast it to the field (furrows).
  • Through the irrigation channel, take 1 litre of formulation and 500 gm of molasses (gur) in 100 litres of water.
  • Mix thoroughly and store for three days, stirring two to three times daily. Irrigate one acre with this 100-litre solution via irrigation channel.
  • Seed Treatment: Apply 100 ml of Acetobacter formulation per 1 kg of seeds. After being uniformly wet, shake them gently to form a uniform layer of culture coating. Then dry the seeds in the shade for 20–25 minutes.
