“…Biosurfactants are low molecular weight surfaceactive compounds widely produced by bacteria, yeast, and fungi. Biosurfactant produced by PGPR, effectively employed for oil recovery, improving soil quality by removing hydrocarbons as well as heavy metals, 70,71 plant-microbe interaction, pharmaceutical, cosmetics, petroleum, and food industries. 72 In the present study, Zea mays growth promotion was evaluated by considering the vegetative plant growth parameters as root and shoot length, fresh, dry root and shoot weight, and dry root and shoot weight ratio.…”

Multiple plant growth-promoting attributes with N-acyl homoserine lactone (AHL)-mediated quorum sensing exhibiting bacterial strains can help plants to withstand varying abiotic and biotic stress conditions for improving the plant health and productivity. In total, 306 bacterial isolates were isolated from diverse locations and sites. In our exploration, bacterial isolates were screened based on AHL production, plant growth-promoting attributes, abiotic stress tolerance, and antagonistic activity against phytopathogenic fungi. Among the screened 306 isolates, 4 (11VPKHP4, 7VP51.8, P51.10, NBRI N7) were selected based on their efficiency in AHL production, biofilm formation, enduring different abiotic stress conditions, exhibiting plant growth-promoting attributes, and antagonistic activity. Based on 16S rRNA gene sequencing analyses of the selected 4 isolates belong to Pseudomonas genera. Selected isolates 11VPKHP4, 7VP51.8, P51.10, and NBRI N7 were also proficient in biosurfactant production, emulsification, suggesting that all isolates fabricate emulsifiers. The plant growth promotion potential of selected 4 bacterial isolates showed significant growth enhancement in all the vegetative parameters of Zea mays under control as well as drought stress condition. Biochemical parameters and defense enzymes under drought stress conditions were also modulated in the PGPR treated plants as compared to their uninoculated respective controls. With quorum sensing, multiple PGPR attributes, stress tolerance, biofilm formation, and EPS production the selected isolates have the potential to facilitate enhanced plant growth, rhizosphere colonization, maintenance of soil moisture content under normal and diverse stresses.

“…The biosurfactant produced by Pseudomonas spp. is a low molecular weight biosurfactant was identified as the amphiphilic surface-active glycolipids (rhamnolipids) that consisting of hydrophobic and hydrophilic molecules [13]. According Gumel [14] Pseudomonas putida can growth in medium fatty acid C8:0 and C18: 1 as carbon and ammonium as nitrogen source that found in waste palm oil effluent.…”

The purpose of this study to determine effect of bio-emulsifier from Pseudomonas putida as feed supplement on the performance of broiler chickens. The experiment was divided in two phases. In phase 1: test of oil bubbles formation in water using bio-emulsifier, and phase 2 : in vivo test bio-emulsifier in animal. 200 one-day-old male and female broiler strain Cobb were used. On d 14, chicks were separated by sex and placed in 40 pens, sex separate (100 males or 100 females) and randomly assigned 4 treatments and 5 replicates of 5 birds each for 14 d (21d-35 d). The diets were based of corn, concentrate and rice bran meal and supplemented with: 0, 0.5,1 and 1.5 g/kg bio-emulsifier. The observed parameters were feed intake (FI), average daily gain (ADG), and feed conversion ratio (FCR). Result of experiment 1: as expected, supplementation of bio-emulsifier was increased small oil bubbles formation in medium oil in water, whereas in experiment 2 showed FI, ADG and FCR unaffected by dietary supplementation with bio-emulsifier on broiler at finisher phase (week 4 and 5) (P>0.05) and did not decrease on broiler performance. The results give new information that bio-emulsifier from Pseudomonas putida could potentially as a new alternative feed additive in the future on broiler performance.

“…Elakkiya et al (2020) produced rhamnolipid (0.34 mg/mL) from cassava solid waste using Pseudomonas aerugimosa TEN01 and achieved highest oil recovery 14.28% using biosurfactant based silver nanoparticle which was similar to chemically produced silver nanoparticle. Haloi et al (2020) have used Pseudomonas sp. TMB2 (KX661384) for production of 2.8 ± 0.5 g/L rhamnolipid and reported overall 27.11% oil recovery efficiency with an additional 16.7% recovery after secondary brine flooding from rock plug NH1.…”
