This research aimed to isolate copper-resistant bacteria from industrial effluents for potential bioremediation in both planktonic and biofilm growth modes. Out of ten isolates effluents, four bacterial strains (S1A, S2C, SSA, S1C) wereselected based on their minimum inhibitory concentration (MIC) biofilm-forming capabilities. These demonstrated strong formation abilities the absence presence copper (Cu) stress, with MIC values 850 μg/ml S1A, S1C, 750 S2C. Physiological characterization revealed that these exhibited optimal at pH 7 37°C. Biochemical indicated similarity genera Staphylococcus (S1C), Bacillus (SSA), Corynebacterium (S1A), Enterobacter (S2C). The removal efficiency was assessed modes using atomic absorption spectroscopy. In growth, all showed efficiencies 81.4% 81% 83.5% (S2C), 82.3% (S1C) after 24 hours, 84% 83.4% 85.3% 84.2% 48 hours.

Marine lipids are recognized for their-health promoting features, mainly being the primary sources of omega-3 fatty acids, and therefore critical human nutrition in an age when global supply these nutrients is experiencing unprecedent pressure due to ever-increasing demand. The seafood industry originates a considerable yield co-products worldwide that, while already explored other purposes, remain mostly undervalued as sustainable healthy lipids, often low-value oil production. These especially appealing lipid since, besides well-known nutritional upside marine animal fat, which particularly rich polyunsaturated they also have interesting bioactive properties, may garner them further interest, not only food, but high-end applications. Besides added value that represent valuable sources, there obvious ecological reducing waste. In this sense, repurposing bioresources will contribute more use strain on heavily depleted stocks. Therefore, untapping potential aligns with both health environmental goals by guaranteeing additional eco-conscious practices.

This study evaluates the heavy metals concentrations in sprat (Sprattus sprattus, Linnaeus, 1758) from Romanian Black Sea, assessing both ecological implications and human health risks associated with consumption. Using long-term data spanning 1994–2019, levels of copper (Cu), cadmium (Cd), lead (Pb), nickel (Ni), chromium (Cr) dorsal muscle tissues were analyzed to identify contamination trends episodic pollution events. Although most remained below regulatory thresholds, occasional exceedances Cd Pb suggest intermittent inputs. Health assessed using dietary indices including estimated daily intake (EDI), target hazard quotient (THQ), total (TTHQ), carcinogenic risk index (CRI). Findings indicate that, under current exposure levels, regular consumption poses minimal risk. However, prolonged during peak periods may contribute cumulative toxic effects, for ecosystem stability food safety. Given persistence their interactions co-occurring pollutants, such as persistent organic pollutants (POPs) polycyclic aromatic hydrocarbons (PAHs), ongoing monitoring remains essential. supports development sustainable environmental policies aimed at protecting marine biodiversity consumer Sea region.

Despite the numerous sensory, organoleptic and nutritional qualities, fish meat may also contain some toxic compounds with negative effects on human health. Polycyclic aromatic hydrocarbons (PAHs) are a class of chemicals resulting from incomplete combustion, found at high levels in thermally processed foods, especially smoked fish.
