Microalgae: A promising strategy for aflatoxin control in poultry feeds
Toxicon. 2024 May 18:107770. doi: 10.1016/j.toxicon.2024.107770. Online ahead of print.ABSTRACTAflatoxins are toxic compounds produced by certain molds, primarily Aspergillus species, which can contaminate crops such as grains and nuts. These toxins pose a significant health risk to animals and humans. Aflatoxin B1 (AFB1) is the most potent of these compounds and has been well-characterized to lead to diminished growth and feed efficiency by disrupting nutrient absorption and metabolism in poultry. AFB1 can trigger apoptosis and inflammation, leading to a decline in immune function and changes in blood biochemistry in poul...

Continuous UV-C/H < sub > 2 < /sub > O < sub > 2 < /sub > and UV-C/Chlorine applied to municipal secondary effluent and nanofiltration retentate: removal of contaminants of emerging concern, ecotoxicity, and reuse potential
This study focuses on the assessment of advanced oxidation processes (AOPs), specifically UV-C/H2O2 and UV-C/Chlorine, for the removal of 14 target CECs in municipal secondary effluent (MSE, spiked with 10 μg L-1 of each CEC) or in the subsequent MSE nanofiltration retentate (NFR, no spiking). Phototreatments were carried out in continuous mode operation, with a hydraulic retention time of 3.4 min, using a tube-in-tube membrane photoreactor. For both wastewater matrices, UV-C photolysis (3.3 kJ L-1) exhibited high efficacy in removing CECs susceptible to photolysis, although lower treatment performance was observed for NF...

Chlorella filled poly(lactic acid) (PLA)/poly(butylene adipate-co-terephthalate) (PBAT) blend bio-composites compatible with additive manufacturing processes: Fluorescent and anti-counterfeiting QR codes applications
Int J Biol Macromol. 2024 May 15:132375. doi: 10.1016/j.ijbiomac.2024.132375. Online ahead of print.ABSTRACTAnti-counterfeiting in 3D printing has gained significant attention, however, current approaches often fall short of fully capitalizing on the inherent advantages of personalized manufacturing with this technology. Herein, we propose an embedded anti-counterfeiting scheme for additive manufacturing, accompanied by a novel fluorescent encrypted quick response (QR) method. This approach involves the development of a 3D printing filament utilizing poly(lactic acid) (PLA) and poly(butylene adipate-co-terephthalate) (PBAT...

Enhancing the biodiesel production in the green alga Chlorella vulgaris by heavy metal stress and prediction of fuel properties from fatty acid profiles
Environ Sci Pollut Res Int. 2024 May 14. doi: 10.1007/s11356-024-33538-w. Online ahead of print.ABSTRACTThe green microalga Chlorella vulgaris was used as a test organism during this study for evaluation of the impact of different heavy metal stress, Mn2+, Co2+, and Zn2+, on enhancing the biodiesel production. The algal cultures were grown for 13 days under heavy metal stress after which were subjected to estimation of growth, some primary metabolites, lipid, and fatty acid profiles. The maximum lipid accumulation (283.30 mg/g CDW) was recorded in the algal culture treated with 3 µM cobalt nitrate. Application of 2 mM man...

Water quality characteristics and ecological risk evaluation of a landscaped river replenished by three reclaimed water sources in Qingdao, China
Environ Sci Pollut Res Int. 2024 May 13. doi: 10.1007/s11356-024-33617-y. Online ahead of print.ABSTRACTThe water crisis may be solved by utilizing reclaimed water. Three reclaimed water sources have restored the lower sections of the Licun River, forming a landscaped river. In this paper, the river's water quality was monitored for a year, and the ecological concerns were analyzed using luminescent bacteria, chlorella, and zebrafish. The results indicated that although basic water quality indicators like COD and ammonia fluctuated along the river, the classification of water quality was primarily affected by factors such ...

Effects of sulfamonomethoxine and trimethoprim co-exposures at different environmentally relevant concentrations on microalgal growth and nutrient assimilation
Aquat Toxicol. 2024 May 6;271:106937. doi: 10.1016/j.aquatox.2024.106937. Online ahead of print.ABSTRACTIn aquaculture around the world, sulfamonomethoxine (SMM), a long-acting antibiotic that harms microalgae, is widely employed in combination with trimethoprim (TMP), a synergist. However, their combined toxicity to microalgae under long-term exposures at environmentally relevant concentrations remains poorly understood. Therefore, we studied the effects of SMM single-exposures and co-exposures (SMM:TMP=5:1) at concentrations of 5 μg/L and 500 μg/L on Chlorella pyrenoidosa within one aquacultural drainage cycle (15 days...

Nicotine exacerbates liver damage in a mice model of Ehrlich ascites carcinoma through shifting SOD/NF- κB/caspase-3 pathways: ameliorating role of Chlorella vulgaris
This study examined the probable ameliorative role of Chlorella vulgaris (ChV) extract against nicotine (NIC)-induced hepatic injury in Ehrlich ascites carcinoma (EAC) bearing female Swiss mice. Sixty female Swiss mice were assigned to four equal groups orally gavaged 2% saccharin 0.2 mL/mouse (control group), orally intubated 100 mg ChV /kg (ChV group), orally intubated 100 µg/mL NIC in 2% saccharin (NIC group), and orally intubated NIC + ChV as in group 3 and 2 (NIC+ChV group). The dosing was daily for 4 weeks. Mice from all experimental groups were then inoculated intraperitoneally with viable tumor cells 2.5 × 106 (0...

Chlorella vulgaris algae ameliorates chlorpyrifos toxicity in Nile tilapia with special reference to antioxidant enzymes and Streptococcus agalactiae infection
CONCLUSIONS: It was concluded that CPF pollution induces immunosuppressed status, oxidative stress, and anemic signs in Nile tilapia.
