It is purposed that total amount of carbon in the form of methane hydrates is almost twice the carbon content in all the fossil fuel reserves put together, and hence these are supposed to be the future potential energy resource. This paper investigates the laboratory investigations on effect of a biosurfactant rhamnolipid on methane hydrate formation kinetics. Rhamnolipid was produced by Pseudomonas aeruginosa strain A11. The presence of P. aeruginosa has been reported in Gulf of Mexico gas hydrate samples. Biosurfactant reduced the surface tension of water from 72 to 36 mN/m with CMC of 70 mg/L. The biosurfactant dose is studied at two different concentrations in the solution at 100 and 1000 ppm. Kinetic of hydrate formation and growth is compared at 0, 100, and 1000 ppm of rhamnolipid showing that rhamnolipid acts as a hydrate promoter at these concentrations. Thus, small dosages of rhamnolipids produced by P. aeruginosa strain A11 must clearly affect the gas hydrate formation kinetics in natural sites (as in Gulf of Mexico).&lt;/p&gt;</style></abstract><custom3><style face="normal" font="default" size="100%">&lt;p&gt;Indian&lt;/p&gt;</style></custom3></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Sakpal, Amrapali</style></author><author><style face="normal" font="default" size="100%">Haq, Nazrul</style></author><author><style face="normal" font="default" size="100%">Dasgupta, Santanu</style></author><author><style face="normal" font="default" size="100%">Alanazi, Fars</style></author><author><style face="normal" font="default" size="100%">Alsarra, Ibrahim A.</style></author><author><style face="normal" font="default" size="100%">Alam, Mahboob</style></author><author><style face="normal" font="default" size="100%">Dastager, Syed G.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Novel biosurfactant assisted biodegradation of polystyrene by Actinomycetes and its chemical understanding</style></title><secondary-title><style face="normal" font="default" size="100%">Polymer Degradation and Stability</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Biodegradation</style></keyword><keyword><style  face="normal" font="default" size="100%">Fatty alkene biosurfactant</style></keyword><keyword><style  face="normal" font="default" size="100%">Glutamicibacter sp.</style></keyword><keyword><style  face="normal" font="default" size="100%">Polystyrene</style></keyword><keyword><style  face="normal" font="default" size="100%">Rhamnolipid</style></keyword><keyword><style  face="normal" font="default" size="100%">Rhodococcus sp.</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2026</style></year><pub-dates><date><style  face="normal" font="default" size="100%">APR</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">246</style></volume><pages><style face="normal" font="default" size="100%">111946</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;
	The current study highlights the effective biodegradation of polystyrene by two actinobacterial strains, Glutamicibacter sp. K-1 and Rhodococcus sp. BG-30. FT-IR, Raman spectroscopy, and GPC data showed the degradation pattern of polystyrene. Additionally, GC-MS analysis showed that strain K-1 produced a variety of degradation by-products, including alkanes, 2,4-Di-ter-butyl phenol, 2-propenoic acid, tridecyl ester, and dibutyl phthalate, while strain BG-30 produced a greater amount of alkenes, phthalic acid, and isobutyl octyl esters. GPC detected a drop in polystyrene's average molecular weight (Mn), which suggests chain scission of the polymer. Changes in polystyrene's roughness and other morphological properties were shown by AFM and FE-SEM. The effects of a conventional rhamnolipid and a novel thermostable biosurfactant fatty alkene (0.1 % each) on the breakdown of polystyrene were examined. Strain K-1 and BG-30 resulted in increasing the degradation of polystyrene to 12 % (w/w) and 16 % (w/w), respectively in the presence of fatty alkene biosurfactant, there was 10 % (w/w) and 8 % (w/w), degradation in presence of rhamnolipid. To the best of our knowledge, degradation of polystyrene by Glutamicibacter sp. has been reported as a newly identified strain and use of a novel biosurfactant together revealed their potential in biodegradation of plastic to mitigate the plastic pollution using microbial resources.&lt;/p&gt;
