The improper disposal and degradation of plastics causes the formation spread micro nano-sized plastic particles in ecosystem. widespread presence these nanoplastics leads to their accumulation biotic abiotic components environment, thereby affecting cellular metabolic functions organisms. Despite being classified as xenobiotic agents, information about sources exposure related reproductive health is limited. Micro nano during early developmental stages can cause abnormal embryonic development. It trigger neurotoxicity inflammatory responses well developing embryo. In development, a comprehensive study role pluripotency, gastrulation, multi-differentiation potential scarce. Due ethical concerns associated with direct use human embryos, pluripotent cells its 3D vitro models (with cell lines) are an alternative source for effective research. Thus, Embryoid body (EB) model provides platform conducting embryotoxicity Pluripotent stem such induced derived embryoid bodies (EBs) serve robust that mimics characteristics similar embryos. EB Accordingly, this review discusses significance Further, we also evaluated possible sources/routes microplastic generation analyzed surface chemistry cytotoxic effects reported till date.

Isolation and Identification of Bacterial Strains Colonizing the Surface of Biodegradable Polymers

Microorganisms, Journal Year: 2025, Volume and Issue: 13(3), P. 609 - 609

Published: March 6, 2025

Plastics play a key role in every sector of the economy, being used manufacturing products fields health, food packaging, and agriculture. Their mismanagement poses serious threat to ecosystems and, general, human life. For this reason, particular attention has been paid last decade use biodegradable polymers (BPs) as an alternative classic plastics. In study, we aimed identify bacterial strains able colonize surface five BPs: poly(butylene succinate) (PBS), succinate-co-butylene adipate) (PBSA), poly(ε-caprolactone), (PCL), poly(3-hydroxybutyrate) (PHB), poly(lactic acid) (PLA). experiment, mesocosms were designed ad hoc mimic conditions which can be found marine environments: i. suspended water column; ii. laying over gravel; iii. under gravel. Four samples taken (3, 4, 10, 12 months from start experiment) BPs incubated above-mentioned three conditions. Our results demonstrated that bacteria belonging Proteobacteria, Actinobacteria, Firmicutes, Bacillota, Bacteroidota, Cyanobacteria phyla most frequent colonizers surfaces analysis, could responsible for their degradation, resulting evolution strategies degrade plastics through secretion specific enzymes.
