Phosphate solubilizing bacteria from subtropical soil and their tricalcium phosphate solubilizing abilities

Abstract: Many soils have the problem of high phosphate retention values (> 85%) thus P is not available for plants. The activity of phosphate solubilizing microbes (PSM) is able to facilitate the availability of phosphorus in the soil. The ability of each microbe to dissolve inorganic phosphate varies and depends on the type of microbe and the microbial growth factors. In nature, almost all forms of life are surrounded by various types of sounds and they also interact with these sounds. Previous research found that the soil that had been applied with the murottal Al-Qur’an sound for 2 hours per day for 7 days increased the total population of soil microbes 23.08% more than without applying murottal sound. This research was carried out in the laboratory of the Faculty of Agriculture, University of Muhammadiyah Sumatera Utara from April to August 2019. This treatment was sounds on 9 rhizosphere of corn, were put into the box. The sounds were treat every morning during 2 hours at 08.00 -10.00 o’clock and compared with 9 rhizosphere of corn was not treated with sounds. The result showed that sound treatment affected the growth of phosphate solubilizing microbes and all microbes that were not pathogenic to plans.

TL;DR: A new DNA polymorphism assay based on the amplification of random DNA segments with single primers of arbitrary nucleotide sequence is described, suggesting that these polymorphisms be called RAPD markers, after Random Amplified Polymorphic DNA.
