Antibiotic and Heavy Metal Co-Resistant Strain Isolated from Enrichment Culture of Marine Sediments, with Potential for Environmental Bioremediation Applications. Antibiotics (Basel) 2023; 12:1379. [PMID: 37760676 PMCID: PMC10526090 DOI: 10.3390/antibiotics12091379] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Revised: 08/20/2023] [Accepted: 08/28/2023] [Indexed: 09/29/2023] Open
Abstract
Antibiotics and heavy metals have caused serious contamination of the environment and even resulted in public health concerns. It has therefore become even more urgent to adopt a sustainable approach to combating these polluted environments. In this paper, we investigated the microbial community of marine sediment samples after 255 days of enrichment culture under Cu (II) and lincomycin stress and ZC255 was the most resistant strain obtained. The 16S rRNA gene sequence confirmed that it belonged to the genus Rossellomorea. Strain ZC255 was resistant to 12 kinds of antibiotics, and had a superior tolerance to Cu (II), Pb (II), Ni (II), Zn (II), Cr (III), and Cd (II). Moreover, it exhibits strong bioremoval ability of Cu and lincomycin. The removal efficiency of Cu (II) and lincomycin can achieve 651 mg/g biomass and 32.5 mg/g biomass, respectively. Strain ZC255 was a promising isolate for pollution bioremediation applications.

Microbial Diversity in the Indian Ocean Sediments: An Insight into the Distribution and Associated Factors. Curr Microbiol 2022; 79:115. [PMID: 35195780 DOI: 10.1007/s00284-022-02801-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2021] [Accepted: 11/23/2021] [Indexed: 11/03/2022]
Abstract
Indian Ocean is the third largest oceanic division of the world and shelter to a huge microbial diversity. These microbes play an important role in the metabolism of carbon, sulfur, nitrogen, and phosphorus in the ocean water. They are also major contributors of carbon fixing and sequestration, as much as terrestrial plants to achieve CO2 emissions reduction. The prokaryotic community in the East Indian Ocean primarily comprises of heterotrophic bacteria like Alphaproteobacteria and Gammaproteobacteria, followed by Firmicutes and Actinobacteria. The Arabian Sea and the Bay of Bengal are typically characterized by presence of vast areas of oxygen minimum zones (OMZs) and have been witnessing a shift in the microbial diversity due to the changing conditions in the ocean water. Several canonical correspondence analyses reveal temperature, salinity, and phosphate levels as crucial environmental factors in propelling the distribution of diazotrophs. The viral consortia are dominated by the Caudovirales, an order of tailed bacteriophages. Due to the rapid change in the environmental factors such as topography, temperature, and sunlight contributing toward climate change, their role in sustaining the chemical composition of the ocean can be drastically affected especially with the evidence of several bacterial and fungal communities responding to latitudinal and temperature change. Therefore, we aim to critically review the status of microbial diversity in Indian Ocean to predict their response toward climate change as they are the sentinels of change in marine life and to understand the dynamics of microbial communities in the various locations of Indian Ocean.

Tang X, Yu L, Yi Y, Wang J, Wang S, Meng C, Liu S, Hao Y, Zhang Y, Cao X, Jian H, Xiao X. Phylogenomic analysis reveals a two-stage process of the evolutionary transition of Shewanella from the upper ocean to the hadal zone. Environ Microbiol 2020; 23:744-756. [PMID: 32657519 DOI: 10.1111/1462-2920.15162] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 06/21/2020] [Accepted: 07/10/2020] [Indexed: 12/17/2022]
Abstract
Shewanella strains are characterized by versatile metabolic capabilities, resulting in their wide distribution in the ocean at different depths. Considering that particle sedimentation is an important dynamic process in the ocean, we hypothesized that hadal Shewanella species evolved from the upper ocean. In this study, we isolated three novel Shewanella strains from deep-sea sediments in the Southwest Indian Ocean. Genome sequencing indicated that strains YLB-06 and YLB-08 represent two novel species in the genus Shewanella. Through phylogenomic analysis, we showed that speciation and genomic changes in marine Shewanella strains are related to water depth. We further confirmed the aforementioned hypothesis and revealed a two-stage process of the evolutionary transition of Shewanella from the upper ocean to the hadal zone by comparative genomics and gene gain/loss analysis. Finally, the transcriptomic analysis demonstrated that recently obtained genes are strictly repressed and may thus play a minor role in the response to environmental changes.

Singh P, Raghukumar C, Parvatkar RR, Mascarenhas-Pereira MBL. Heavy metal tolerance in the psychrotolerant Cryptococcus sp. isolated from deep-sea sediments of the Central Indian Basin. Yeast 2013; 30:93-101. [PMID: 23456725 DOI: 10.1002/yea.2943] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2012] [Accepted: 01/21/2013] [Indexed: 11/10/2022] Open
Abstract
A deep-sea isolate of the psychrotolerant yeast Cryptococcus sp. (NIOCC#PY13) obtained from polymetallic nodule-bearing sediments of the Central Indian Basin was examined for its capacity to grow in the presence of various concentrations of the heavy metal salts i.e., ZnSO4 , CuSO4 , Pb(CH3 COO)2 and CdCl2 . It demonstrated considerable growth in the presence of 100 mg/l concentrations of the above-mentioned four heavy metal salts both at 30°C and 15°C. This strain tolerated comparatively higher levels of these four metal salts than other deep-sea and terrestrial yeast isolates belonging to Cryptococcus, Rhodotorula, Rhodosporidium and Sporidiobolus spp. Optimum pH for growth of this isolate was in the range of 6-8 in the presence of heavy metal salts at these two temperatures. Scanning electron microscopic (SEM) studies exhibited altered cell surface morphology of the cells under the influence of heavy metals compared to that with control. The adsorption of heavy metals to the cells was demonstrated by FTIR and EDAX analysis. As evidenced by atomic absorption spectrophotometric (AAS) analysis, about 30-90% of the heavy metals were removed from the culture supernatant after 4 days of growth at 30°C. This deep-sea yeast isolate appears to be a potential candidate for bioremediation of metal-contaminated sites. Moreover, its metal tolerance properties provide a significant insight into its ecological role and adaptations to growth in such extreme conditions.
