“…Polylactic acid-degrading ability in microorganisms are not widely distributed as PLA degraders are less discovered than other types of plastic degrading microorganisms (Nishida and Tokiwa, 1993;Pranamuda et al, 1997;Suyama et al, 1998;Tokiwa et al, 2009). Actinobacteria are among the few microorganisms with potential for PLA degradation (Jarerat et al, 2002Sukkhum et al, 2009aSukkhum et al, ,b, 2011Sukkhum et al, , 2012Chomchoei et al, 2011;Konkit et al, 2012;Penkhrue et al, 2015Penkhrue et al, , 2018Panyachanakul et al, 2017Panyachanakul et al, , 2019. PLA-degrading actinobacteria are affiliated with 26 species in 11 genera namely Actinomadura, Amycolatopsis, Kibdelosporangium, Micromonospora, Nonomuraea, Pseudonocardia, Saccharothrix, Streptoalloteichus, Streptomyces, Thermomonospora, and Thermopolyspora ( Table 1).…”

“…PDLLA-degrading enzyme production of 766.33 U/mL with 15.97 U/mL•h of enzyme productivity were achieved with the optimum fermentation conditions of 0.25 vvm aeration, 170 rpm agitation and 45 • C incubation temperature for 48 h in batch fermentation using 5L stirrer fermenter. Recently, a scaleup for PLA degrading enzyme production by A. keratinilytica T16-1 in a 5L stirred tank bioreactor was carried out under batch condition (Panyachanakul et al, 2019). The best condition for PLA degradation was an agitation speed of 50 rpm at 60 • C under a controlled pH of 8.0.…”

“…Moreover, the shear force of the impeller stimulated the breakdown of bioplastic structures. Panyachanakul et al [22] also found that agitation in the stirrer fermenter positively impacted the degradation of bioplastics. Lomthong et al [14] reported that increasing the agitation rate in the stirrer reactor to 200 rpm accelerated the degradation of PLA polymer (100 g/L) by up to 68 %.…”

“…Esterase and lipase are important hydrolytic enzymes that can cleave the internal ester bonds of these polyesters. In addition to both of these enzymes, proteases can degrade the members of the poly(α-hydroxy acid) family as a result of the α-ester linkages in their backbone [14]. These degradation products (i.e., PLA, PGA, and PLGA) can enter the Krebs cycle and be eliminated from the body as carbon dioxide (CO 2 ) and water, resulting in the high biocompatibility of aliphatic polyesters [12].…”
