Analysis of phosphate solubilizing bacteria in soil

Therefore, only to increase the planting area of domestic kiwifruit is difficult to fully meet the domestic demand. Burkholderia is known as N-fixing bacteria and exhibited antifungal activity Stephen and Jisha, ; Mubarik et al.

Growth Law of the Kiwifruit and the Effect of Microorganisms on the Growth of Plants Growth law of kiwifruit Because of its rich nutrients, kiwifruit is no longer used as a kind of people's daily consumption of fruit, and it has been gradually developed into a new type of health food.

Four treatments were administered to air-dried and sieved 2 cm purple soil Table 2: The pH value of soil is 5. Observation of the presence of N2-fixing, P- and K-solubilizing bacteria was accorded to Perez et al. In contrast to our triple inoculation with B. In recent years, microbial fertilizer has become more and more widely used in agricultural applications.

While the total amount of phosphorus is 0. With the extensive and long-term use of chemical fertilizers and pesticides in agricultural production, there are a lot of pollutants in the soil which are difficult to be degraded. The US biofertilizers market is segmented by microorganisms into rhizobium, azotobacter, azospirillum, blue-green algae, phosphate solubilizing bacteria, mycorrhiza, and other microorganisms.

Since biofertilizers are often stored under non-ideal conditions e. Phylogenetic analysis was performed using Mega 5. Current chemical production process cannot utilize rock phosphate rich in impurities such as ferrous, silica, magnesium, etc.

For determining the best concentration of N-source to accelerate multiplication of microflora for accelerated solubilization of RP-P, different N levels should be tested. Biotechnological solubilization of rock phosphate on media containing agro-industrial wastes.

An un-inoculated tube is used as a control. Organic waste material is collected and sorted out to remove unwanted substances. The available zinc, iron, copper and manganese were recorded higher in forest land use systems with maximum values being 3.

Dried organic matter along with rock phosphate is transferred into a composting unit. The needs of P and K in plants are usually obtained through fertilizer application. A pot experiment then examined its effects of this complex inoculant on soil microflora, soil N2-fixation, P- and K-solubility and kiwifruit growth under four treatments.

Whereas the size of the colony increased up to 3 days of incubation and with no considerable change thereafter, up to 7 days of incubation. Fourth, the preferred embodiment of the present invention use all types of rock phosphate available across the globe to produce high quality organic phosphate.

Correlation coefficient was calculated for the data wherever necessary. P ratio and mineralization potential in spiked soil. The biochemical characteristics of these three isolates are presented in Table 1. Because most arid and semi-arid soil regimes are deficient in phosphorus, phosphatic fertilizers are required to replenish the phosphorus demanded by crop plants.

An agar medium is prepared where in rock phosphate is the sole phosphorous source. After incubation, the white, translucent, convex colonies with high mucilage were isolated and pure cultures were maintained after sub culturing on the same medium.

The experiment is performed three times to ensure consistent replication. Through the comparative analysis, it can be seen that the growth and development of the experimental group with beneficial microorganisms in the soil was better than that of the control group, and the disease resistance was better, which could absorb the elements such as Nitrogen NPhosphorous PPotassium K and so on.

The final pH of the supernatant was measured and the P2O5 liberated was estimated by the method given in [ 12 ]. As further shown in FIG.

Crop plants are uprooted at different growth stages and brought to the laboratory in pre-sterilized polythene bags. Several strains of potassium solubilizing bacteria, such as Pseudomonas, Burkholderia, Acidothiobacillus ferroxidans, Bacillus mucilogenosus, B.

Rhizhobium and Bradyrhizobium, J.soil attached to the root. Rhizosphere: rest of the soil. Roots • SDSGE-PA analysis on the isolated bacteria An assay for screening for phosphate solubilizing bacteria is still in development.

Conclusion. Single bacteria colonies are picked from the. The Effects of Different Insoluble Phosphate Media on Phosphate Solubilizing Bacteria from Mendocino Terrace Soil Danielle Naiman1, Alex Aaring2, Shi Wang2, Bryson Cwick2, Romy Chakraborty2 Transfer-to-Excellence Research Experiences.

Phosphate solubilizing bacteria are able to solubilize phosphate and made it isolating the bacteria at some point soil samplings. All bacteria were isolated and using Pikovskaya (PVK) agar [9]. The qualitative analysis of phosphate solubilisation potential of selected Phosphate Soluble Bacteria.

A soil survey was conducted at Doda district in the month of April to assess the various physico-chemical and biological properties of the soil.

Composite surface soil samples () were collected at a. ABSTRACT: Application of phosphate-solubilizing bacteria (PSB) has been shown to promote plant growth and development in the field and under controlled environmental conditions.

The effects of PSB on microbial activity and soil.
