Isolations and Characterization of Novel Bacterial Species from Cyprinus Carpio and Its Use in Biodegradation of Polystyrene with Emphasis on SDG 3 for Ensuring Healthy Lives and Well-Being for All Humans and Animals
AI summary Read the abstract
Novel bacterial species isolated from the gastrointestinal tract of common carp (Cyprinus carpio) were identified via 16S rRNA sequencing and tested for polystyrene biodegradation capability, with findings supporting the potential of gut microbiome bacteria as probiotics for plastic bioremediation.
Objective: This research aims to investigate the feasibility of employing beneficial bacterial species present in the gastrointestinal tract (GIT) of common carp (Cyprinus carpio) in order to biodegrade microplastics (MP), which can provide healthy lives for both humans and animals. Theoretical framework: the main concept in this research is that the bacterial communities found in (GIT) of both people and animals can produce beneficial effects. Microorganisms that are beneficial to the host and are typically found in GIT are generally referred to as probiotics: Method: The 16S rRNA sequencing method was utilized to determine the species present in the bacterial community of Cyprinus carpio. The novel species Hafnia parallel UUNT_MP29 was utilized to conduct the biodegradation investigation. PS was used as the sole source of carbon. Discussion and the Results: During the PS batch experiment, this strain reached its highest point on the fifteenth day, displaying an incubation rate of 1.3x108 CFU/mL. Following that, the microbe entered a stationary phase, which it remained in until the experiment was finished on the 20th. According to the results, this strain appears to be a new indigenous variation capable of biodegrading PS compounds. Originality/Value: This study contributes to the existing body of knowledge by discovering bacterial species from common carp that have the potential to degrade PS. The possible application of Hafnia paralvei UUNT_MP29 in the rehabilitation of wastewater polluted by microplastics demonstrates the significance and utility of this research.

Biodegradation of Polystyrene by Hafnia paralvei: A Novel Isolate from the Gastrointestinal Tract of Common Carp
AI summary Read the abstract
Scientists found a new gut bacterium in carp (a fish that feeds on the bottom, where plastic waste accumulates) that can break down polystyrene, a common plastic found in food containers and packaging, eating away nearly 17% of it in just 16 days. This matters because microplastics are increasingly found in our water, food, and even our bodies, and discovering natural bacteria that can break down plastic waste could lead to new tools for cleaning up pollution before it reaches our plates.
