- Description
- The significant surge in population, combined with the degradation of the environment, has imposed substantial stress on worldwide food newlinesecurity. The concerning pace of population growth, along with escalating environmental harm due to heightened industrialization, newlinehas indeed exerted considerable pressure on the global food provision. Considering the existing situation, the sustainable approach to enhance agricultural yield and facilitate environmental bioremediation entails utilizing endophytes that reside within plants. Endophytic microorganisms possessing the capacity to promote plant growth and exert biocontrol can significantly boost plant development amidst fluctuating environmental factors, both biotic and abiotic in nature. The current research aimed to extract bacterial and fungal endophytes from Alternanthera philoxeroides and newlineAlternanthera paranichoides and evaluate their potential for enhancing plant growth and controlling pests. Among the isolated newlineendophytic bacteria, Klebsiella pneumoniae exhibited various characteristics conducive to plant growth, leading to enhanced newlinegermination and vegetative growth in Vigna unguiculata plants. The isolate exhibited good Indoleacetic acid (IAA) production newline(48.752.95 g/mL) and potassium solubilization (2.130.07 ppm). The IAA production by K. pneumoniae was further enhanced by 4- fold using the RSM optimization to 195.662.51 g/mL. The newlineendophytic bacteria Bacillus amyloliquefaciens and Bacillus subtilis newlineshowed good extracellular enzyme production and antimicrobial activity along with plant growth promotion. The endophytic bacterium B. amyloliquefaciens showed good newlinebiosurfactant production and bioremediation efficiency. The strain displayed notable resistance to Cr and Pb concentrations upto 2000 mg/L. It was found to possess maximum metal removal efficiency for Pb, 92.3% at pH 9 and 86.2 at 25 oC.
