“…Although pathogenic Vibrio strains are hazards for coastal systems (5,(8)(9)(10), most Vibrio strains are harmless (5). Vibrios are present in a great variety of aquatic environments from coastal areas to the deep sea (2,5), indicating that they occupy a wide range of environmental niches.…”

Vibrio spp. are ubiquitous marine bacteria with high metabolism flexibility and genome plasticity. Previous studies have revealed the dynamics of planktonic vibrios in relation to environmental forces, such as temperature and salinity. However, little is known about Vibrio ecology in benthic environments. Here, we elucidate the abundance, diversity, and spatial distribution of Vibrio spp. in sediments of the Chinese marginal seas, with a wide spatial range from north to south covering the Yellow Sea (YS), East China Sea (ECS), and South China Sea (SCS). Quantitative analysis showed that Vibrio spp. were most abundant in the SCS (ϳ9.04 ϫ 10 5 copies/g) compared to the YS (ϳ1.00 ϫ 10 5 copies/g) and ECS (ϳ8.86 ϫ 10 5 copies/g). Vibrio community compositions derived from Illumina sequencing of Vibrio-specific 16S rRNA genes varied significantly between sampling areas, which was reflected by a strong distance-decay pattern. The spatial distribution of Vibrio was governed by a joint effect of spatial and environmental factors (especially temperature, salinity, and SiO 3 2Ϫ ), and their respective pure effects explained only a small fraction of the community variation. Moreover, we identified the most prominent operational taxonomic units (OTUs) that were partitioned in these sea areas. Whereas Vibrionaceae OTU20 and Photobacterium lipolyticum were prevalent in the YS, Vibrio gigantis and Photobacterium piscicola, and P. piscicola, Photobacterium lutimaris, and Photobacterium alginatilyticum were prevalent in the ECS and SCS, respectively. Our study demonstrated clear spatial heterogeneity of Vibrio spp. in sediments of the Chinese marginal seas, laying a foundation for fully understanding the marine Vibrio ecology and the ecological roles of the species. IMPORTANCE Vibrio is an important component of natural marine microbial populations in terms of pathogenicity and roles in carbon cycling. Compared to the marine pelagic environment, our knowledge of the diversity and distribution pattern of Vibrio spp. in sediment is limited. Here, we show higher Vibrio abundance in Chinese marginal seas than in other studied sediments. There was a clear spatial differentiation of Vibrio abundance and community composition in different sea areas. The benthic Vibrio community displayed a strong distance-decay pattern across a wide spatial range, which was formed under the combined effects of spatial and environmental factors. These results provide deep insights into the ecological dynamics of Vibrio and its environmental controls, facilitating a more comprehensive understanding of the marine Vibrio ecology.

“…Nevertheless, many reports have not found any correlation between temperature and/or salinity and Vibrio density [41,47,48], suggesting that this parameter can be related with other physicochemical parameters [41]. Organic matter and nutrient enriched environments support high Vibrio densities [49] that may be related to anthropogenic activities.…”

Vibrio spp.: Life Strategies, Ecology, and Risks in a Changing Environment

et al. 2022

Vibrios are ubiquitous bacteria in aquatic systems, especially marine ones, and belong to the Gammaproteobacteria class, the most diverse class of Gram-negative bacteria. The main objective of this review is to update the information regarding the ecology of Vibrio species, and contribute to the discussion of their potential risk in a changing environment. As heterotrophic organisms, Vibrio spp. live freely in aquatic environments, from marine depths to the surface of the water column, and frequently may be associated with micro- and macroalgae, invertebrates, and vertebrates such as fish, or live in symbiosis. Some Vibrio spp. are pathogenic to humans and animals, and there is evidence that infections caused by vibrios are increasing in the world. This rise may be related to global changes in human behavior (increases in tourism, maritime traffic, consumption of seafood, aquaculture production, water demand, pollution), and temperature. Most likely in the future, Vibrio spp. in water and in seafood will be monitored in order to safeguard human and animal health. Regulators of the microbiological quality of water (marine and freshwater) and food for human and animal consumption, professionals involved in marine and freshwater production chains, consumers and users of aquatic resources, and health professionals will be challenged to anticipate and mitigate new risks.

“…Setelah diketahui komposisi bakteri pada sampel yang diperkaya, maka dapat ditentukan golongan bakteri yang berpotensi sebagai agen remediasi perairan Sungai Citarum, khususnya wilayah hilir Muara Gembong. Meskipun studi ini mengidentifikasi komunitas bakteri pada sampel air yang telah diperkaya, secara alaminya Gammaproteobacteria menjadi kelas dominan yang ditemui di sepanjang estuari (Ghosh & Bhadury, 2018;Ibekwe et al, 2016;Jeffries et al, 2016;Nakatsu et al, 2019;Wang et al, 2016;) Kelimpahan bakteri Vibrio di wilayah estuari berkaitan erat dengan efek antropogenik, terutama pada meningkatnya jumlah nutrisi dan bahan organik (Costa et al, 2010). Bakteri Vibrio di perairan laut memiliki peran dalam fiksasi nitrogen (West et al, 1985) dan degradasi polutan organik spesifik (West et al, 1983), sehingga sangat mendukung dalam pemulihan perairan terhadap pencemaran lingkungan.…”

Perairan Sungai Citarum banyak memperoleh limpasan limbah antropogenik dari darat yang dapat menimbulkan pencemaran lingkungan. Untuk mengatasi masalah pencemaran tersebut, bakteri dapat dimanfaatkan sebagai agen bioremediasi. Hingga saat ini belum tersedia informasi komunitas bakteri di Perairan Sungai Citarum, khususnya dari wilayah hilir Muara Gembong. Penelitian ini bertujuan untuk mengidentifikasi komunitas, kelimpahan, dan keanekaragaman bakteri dari Perairan Muara Gembong yang telah diperkaya dengan pendekatan metagenomik, serta analisis fungsional dengan melihat profil protein yang dimiliki dari bakteri yang teridentifikasi yang berpotensi sebagai agen bioremediasi. Pengambilan sampel air dilakukan di dua lokasi (A1 dan A2) dengan karateristik perairan yang berbeda. Sampel air estuari diperkaya dengan 0,2x Nutrient Broth. Sekuensing dilakukan dengan metode Next Generation Sequencing (NGS) menggunakan amplikon sekuensing platform Novaseq Illumina, dengan primer 16S rRNA region V3-V4 (341F dan 806R). Hasil identifikasi menunjukkan terdapat 37 genera, 19 famili, 13 ordo, 7 kelas, dan 4 filum bakteri dengan 49 OTU untuk sampel A1 dan 48 OTU untuk sampel A2. Kelimpahan tertinggi diperoleh pada kelas Gammaproteobacteria (99,82%) yang didominasi oleh genus Vibrio. Keanekaragaman bakteri pada kedua sampel diperkaya ini tergolong sedang dengan tingkat dominasi tinggi. Analisis fungsional menunjukkan kemampuan bakteri yang teridentifikasi mampu mendegradasi benzoat, dioxin, asam lemak, metana, naftalen, nitrotoluen, PAH, dan sulfur dengan protein dan enzim yang terlibat dalam metabolisme tersebut. Penelitian ini menunjukkan bakteri yang teridentifikasi pada Perairan Muara Gembong mempunyai potensi bioremediasi untuk cemaran lingkungan, seperti polutan organik dari logam berat.
