Zobellella denitrificans is a gram-negative, facultatively anaerobic, heterotrophic and denitrifying bacterium from the genus of Zobellella which has been isolated from sediments from a mangrove ecosystems from Miaoli County in Taiwan. [1] [2] [3] [4] [5]
Recent research on Z. denitrificans ZD1 has highlighted its versatile applications in biotechnology and aquaculture. This salt-tolerant strain can produce high poly(3-hydroxybutyrate) (PHB), a biodegradable biopolymer, from various organic waste sources, including synthetic crude glycerol, saline wastewater, and municipal wastewater. [6] It can also grow on other agro-industrial wastewaters to produce PHB, including sugary waste slurry, cheese whey wastewater, food waste fermentation liquid, and fishmeal wastewater. [7] This non-sterile PHB production process offers a low-cost strategy for recycling organic waste into valuable bioplastics, reducing reliance on petrochemical-based plastics.
Furthermore, Z. denitrificans ZD1 shows potential as a multifunctional feed ingredient for aquaculture. [8] When utilized as single-cell protein (SCP) rich in PHB, ZD1 can enhance the growth, immune response, and gut microbiome health of various aquatic species. [7] [8] [9] PHB and its intermediates exhibit antimicrobial properties against common aquaculture pathogens, providing an alternative to traditional antibiotics. [10] [11] [12] This dual capability of Z. denitrificans ZD1 to produce bioplastics and serve as a sustainable feed ingredient supports its promising role in addressing environmental challenges in aquaculture.
