“…Although metal-resistant strains isolated from contaminated areas have been described ( Amoroso et al, 2001 ; Schmidt et al, 2005 ; Schmidt et al, 2009 ; Polti, Amoroso & Abate, 2007 ; Albarracin et al, 2008 ; Haferburg et al, 2008 ; Siñeriz, Kothe & Abate, 2009 ; Lin et al, 2011 ; El Baz et al, 2015 ), there is limited information about the physiology of Streptomyces in presence of environmental metal pollutants. Due to the naturally high concentrations of certain heavy metals in Chilean northern Patagonia ( Guevara et al, 2004 ; Revenga et al, 2012 ; Hermanns & Biester, 2013 ) product of the highly active seismic and volcanic activity ( Pantoja, Luis Iriarte & Daneri, 2011 ), the ability of Streptomyces sp. H-KF8 to grow in several metal(loid)s supplemented media was evaluated.…”

Streptomyces sp. H-KF8 is an actinobacterial strain isolated from marine sediments of a Chilean Patagonian fjord. Morphological characterization together with antibacterial activity was assessed in various culture media, revealing a carbon-source dependent activity mainly against Gram-positive bacteria (S. aureus and L. monocytogenes). Genome mining of this antibacterial-producing bacterium revealed the presence of 26 biosynthetic gene clusters (BGCs) for secondary metabolites, where among them, 81% have low similarities with known BGCs. In addition, a genomic search in Streptomyces sp. H-KF8 unveiled the presence of a wide variety of genetic determinants related to heavy metal resistance (49 genes), oxidative stress (69 genes) and antibiotic resistance (97 genes). This study revealed that the marine-derived Streptomyces sp. H-KF8 bacterium has the capability to tolerate a diverse set of heavy metals such as copper, cobalt, mercury, chromate and nickel; as well as the highly toxic tellurite, a feature first time described for Streptomyces. In addition, Streptomyces sp. H-KF8 possesses a major resistance towards oxidative stress, in comparison to the soil reference strain Streptomyces violaceoruber A3(2). Moreover, Streptomyces sp. H-KF8 showed resistance to 88% of the antibiotics tested, indicating overall, a strong response to several abiotic stressors. The combination of these biological traits confirms the metabolic versatility of Streptomyces sp. H-KF8, a genetically well-prepared microorganism with the ability to confront the dynamics of the fjord-unique marine environment.

“…Trace elements exhibit variable biomagnification behaviour in food webs. While mercury, in its organic form, is known to biomagnify (Lavoie et al 2013), other elements such as arsenic and lead show clear biodilution, decreasing in concentration with increased trophic position (Campbell et al 2005a, Cui et al 2011, Revenga et al 2012). Elements such as copper, cadmium, selenium and zinc biomagnify in some but not all food chains (Croteau et al 2005, Cui et al 2011, Cardwell et al 2013, in part depending on baseline concentrations, with lower biomagnification associated with higher baseline concentrations (DeForest et al 2007).…”

Vanadium and thallium exhibit biodilution in a northern river food web

Trophic transfer of contaminants dictates concentrations and potential toxic effects in top predators, yet biomagnification behaviour of many trace elements is poorly understood. We examined concentrations of vanadium and thallium, two globally-distributed and anthropogenically-enriched elements, in a food web of the Slave River, Northwest Territories, Canada. We found that tissue concentrations of both elements declined with increasing trophic position as measured by  15 N. Slopes of log [element] versus  15 N regressions were both negative, with a steeper slope for V (-0.369) compared with Tl (-0.099). These slopes correspond to declines of 94% with each step in the food chain for V and 54% with each step in the food chain for Tl. This biodilution behaviour for both elements meant that concentrations in fish were well below values considered to be of concern for the health of fish-eating consumers.Further study of these elements in food webs is needed to allow a fuller understanding of biomagnification patterns across a range of species and systems.

“…Defining water quality, sediment quality, and the biological characteristics of an aquatic ecosystem is important, especially in terms of the effects of heavy metals on the aquatic environment. Therefore, heavy metal pollution in the aquatic environment has been studied by numerous authors around the world (e.g., Fernandes et al [2012], Karadede-Akin andÜnlü [2007], Masoud et al [2007], Mishra and Mohanty [2008], Monikh et al [2013], Uysal et al [2009], and Revenga et al [2012]).…”

Porsuk Stream is one of Turkey's most important river systems and also one of the most important branches of the Sakarya River. It provides drinking and utility water for two Turkish cities (Kiitahya and Eski §ehir) with a total population of one million. In this study, water, sediment, and some tissues (liver, gill, and muscle) of five cyprinid fish species were collected seasonally (2010-2011) from eight stations on the Porsuk Stream, and the zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn), nickel (Ni), lead (Pb), and arsenic (As) levels of collected samples were determined. The data observed were evaluated with national and international quality criteria. Based on the data observed, it was determined that the Porsuk Stream is affected by significant inorganic pollution from the Kiitahya and Eski §ehir Provinces. It was also determined that the Porsuk Dam Lake has an important cleaning capacity and that the water and sediment quality of the Porsuk Stream improves after the output of the dam lake.
