Project description:In addition, a quantitative analysis of the Paracoccus sp. P-2 proteome identified 3,052 proteins, with 2,705 exhibiting significant differential abundance (FC ≥ 1.5 or FC ≤ 0.6667, and P-value ≤ 0.05) following deltamethrin exposure. Among them, many up-regulated differentially expressed proteins were enriched in carbohydrate and energy metabolism pathways, indicating that Paracoccus sp. P-2 enhances its basal metabolic activity in response to deltamethrin-induced stress. More importantly, enzymes be-longing to hydrolases, decarboxylases, and those involved in multiple xenobiotic met-abolic pathways were upregulated and are likely to participate in the degradation of deltamethrin. This study elucidates the impact of deltamethrin on bacterial metabo-lism and its degradation mechanism by Paracoccus sp. P-2, providing crucial insights and microbial resources for researching pyrethroid biodegradation.
