Isolation and characterization of beneficial endophytic bacteria from Oryza Sativa cultivated in acid sulfate soil
Abstract: Pyrite (FeS2) oxidation in acid sulfate soil led to high acidity and aluminium (Al) and/or iron (Fe) toxicity to the plant. This problem causes nutrient deficiency and root inhibition, which retards plant nutrient uptake efficiency for growth. Plant-microbe interaction is one of the most i...
