What is PSB Photosynthetic bacteria?
PSB (Photosynthetic bacteria), just as the name suggests, are a special and unique class of microorganisms that has the ability to convert light energy into chemical energy using their light-absorbing pigments and reaction centres.
What is PSB in Aquaculture?
Photosynthesis Bacteria (PSB) helps in the health management of the aquaculture and benefits the aquatic life like shrimps or fish. It also helps degrade organic waste and keeps the pond bottom clean. The bacterial cell wall of these bacteria is more digestible.
What is an example of photosynthetic bacterium?
Examples of photosynthetic bacteria are Cyanobacteria, Chlorobi (green sulfur bacteria), Proteobacteria (also known as purple bacteria), and Chloroflexi (filamentous bacteria also known as green non-sulfur bacteria), Proteobacteria (also known as purple bacteria), etc.
Where can you find photosynthetic bacteria?
Photosynthetic bacteria are prokaryotes that are capable of carrying out photosynthesis. They are widely distributed occupying several habitats like soil, lakes, paddy fields, oceans, rivers, and activated sludge (Koblížek et al. 2006; Okubo et al. 2006).
How do you use PSB bacteria?
Use of Bio Fertilizers – Phosphorus Solublising Bacteria PSB – YouTube
What is PSB Fertiliser?
PSB can be used for all crops including paddy, millets, oilseeds, pulses and vegetables. Methods recommended for application are: ☛ Seed treatment ☛ Seedling dipping ☛ Soil application Seed treatment: Same as described for Rhizobium.
How do you create a PSB culture?
Whisk an egg, two tablespoons of fish sauce, and half tablespoon of msg. Add two tablespoons of the eggy-fishy mixture to a 1.25lt plastic bottle and shake it up with the water sample. Bathe in sun for 2-4 weeks. The resulting colour will depend on what PSB is present and the duration of the sun bathing.
What is the benefit of photosynthetic bacteria?
Photosynthetic bacteria have developed an extraordinary metabolic versatility. They can transform light energy into biochemically useful energy but also grow with or without oxygen, via aerobic or anaerobic respirations.
What are the two types of photosynthetic bacteria?
Phototrophy is the process by which organisms trap light energy (photons) and store it as chemical energy in the form of ATP and/or reducing power in NADPH. There are two major types of phototrophy: chlorophyll-based chlorophototrophy and rhodopsin-based retinalophototrophy.
What is the most common photosynthetic bacteria?
Purple bacteria are probably the most widely studied photosynthetic bacteria, being used for all sorts of scientific endeavors including theories on possible microbiological life on other planets.
How do you apply PSB to soil?
Dosage: Suspension of one kg in 10 to 15 litre of water for treating of seedlings for one acre. Soil application: Mix 3-5 kg inoculant with 50 kg finely powdered FYM. Broad cast this mixture at the time of last ploughing. Note : In case of PSB, best results are obtained when applied with well decomposed organic manure.
How do you prepare PSB bacteria?
Phosphate Solubilizing Bacteria (PSB) – English – YouTube
What is the function of PSB?
Phosphate solubilizing bacteria (PSB) are the main contributors of plant nutrition in agriculture and could play a pivotal role in making soluble phosphorus available to plants (Khan et al., 2010).
Which of the following are example of PSB?
Many different strains of these bacteria have been identified as PSB, including Pantoea agglomerans (P5), Microbacterium laevaniformans (P7) and Pseudomonas putida (P13) strains are highly efficient insoluble phosphate solubilizers.
Is photosynthetic bacteria good for plants?
Photosynthetic bacteria (PSB) have been extensively used in agriculture to promote plant growth and to improve crop quality. Their potential application in plant disease management, however, is largely overlooked.
How do photosynthetic bacteria grow?
In the photosynthetic bacteria anaerobic fermentation cultivation process, organic acid salt is taken as main carbon source, 0.25-2.00g/L molasses is added in culture medium, so that pH value of culture is stabilized to be in the range applicable to photosynthetic bacteria growth, cell concentration of the cultured …
How do you use PSB fertilizer?
How do you identify phosphate solubilizing bacteria?
For P-solubilizing ability determination, the isolates were screened by culturing at 28°C on the media supplemented either lecithin (Po culture medium) or Ca3(PO4)2 (Pi culture medium). When the colonies appeared in 4–5 days, those causing a clear phosphate-solubilizing zone were selected out for further calculation.
