Antimicrobial Mitigation via Saponin Intervention on Escherichia coli and Growth and Development of Hydroponic Lettuce

Various saponins have demonstrated allelochemical effects such as bactericidal impacts well antimycotic activity against some plant pathogenic fungi, thereby acting to benefit growth and development. A commercial saponin solution was evaluated for Escherichia coli of lettuce ( Lactuca sativa ) in a hydroponic system. E. (P4, P13, P68) inoculum at final concentration 10 8 colony-forming units (cfu)/mL added 130 L fertilized recirculating nutrient film technique (NFT) system used grow ‘Rex’ lettuce. After 5 weeks the NFT system, populations were lowest inoculated treatment that did not contain any addition (0.89 log cfu/mL) when compared with all other treatments P < 0.001). The containing 100 µg·mL −1 extract had an population 4.61 cfu/mL after higher than 25 or less 0.0001). Thus, observed concentrations. Plant also inhibited by increasing Fresh dry shoot weight both uninoculated without Lettuce head diameter smaller exposed concentrations 50 leaves tested potential travel systemically edible portions plant. No found this manner. It concluded steroidal extracted from mojave yucca Yucca schidigera are acceptable compound use mitigation fertilizer due its ineffectiveness bactericide negative impact on growth.
