The present invention provides a Paracoccus aminovorans BM109 strain (Accession number KCTC 15059BP) having excellent removal of trimethylamine (TMA) or trimethylamine N-oxide (TMAO), and a pharmaceutical composition for preventing or treating diseases caused by TMA or TMAO, a health functional food composition for preventing or improving diseases caused by TMA or TMAO, and a feed composition for preventing or improving diseases caused by TMA or TMAO, including the strain as an active ingredient.

A genetically modified prokaryotic cell comprising: at least one of the following: i. an addition, deletion and/or alteration of at least one gene to promote to taurine production; and ii. an addition, deletion and/or alteration of at least one gene related to taurine cellular transportation; and at least one of the following polynucleotide sequences: i. a vanin (vnn) polynucleotide sequence selected from the group consisting of: vanin-1 (vnn1), wherein said vnn1 polynucleotide sequence has at least 70% sequence coverage to SEQ 3 or SEQ 98, and at least 70% sequence identity to SEQ 3 or SEQ 98; vanin-2 (vnn2), wherein said vnn2 polynucleotide sequence has at least 70% sequence coverage to SEQ 100, and at least 70% sequence identity to SEQ 100; and vanin-3 (vnn3), wherein said vnn3 polynucleotide sequence has at least 70% sequence coverage to SEQ 141, and at least 70% sequence identity to SEQ 141; ii. a cysteamine dioxygenase (ado) polynucleotide sequence which has at least 70% sequence coverage to SEQ 1, and at least 70% sequence identity to SEQ 1; and iii. a flavin-containing monooxygenase 1 (fmo1) polynucleotide sequence which has at least 70% sequence coverage to SEQ 5 or SEQ 99, and at least 70% of sequence identity to SEQ 5 or SEQ 99.

The present invention introduces an innovative approach for the manipulation of microorganisms to generate colored bioplastics. This is achieved by concurrently expressing genes responsible for pigment production and genes involved in bioplastic synthesis within a microbial host. These genes can be synthesized, obtained from a different host through cloning, or naturally occurring within the host organism. The resultant color compounds become encapsulated within the extended bioplastic polymers within the cells, resulting in the formation of naturally pigmented bioplastics.
