The uniqueness of their chemical structure or their interaction with the environment determines the nature of pesticides. In most cases, farmers and consumers of these products, although they know their serious effects, still cannot limit their consumption. Pesticides have harmful effects on soil and human ecosystems that affect molecules, tissues and biological organs and cause acute or chronic disorders. These disorders affect people of all ages, including during pregnancy. These pollutants affect aquatic systems when released. Water molecules in the river are affected by the accumulation of these toxic pollutants with alkaline pH and heavy metals, which can negatively affect the health of plants and animals. This article discusses the scientific literature on the various modification technologies available for safer pesticide use. The use of microorganisms and biological methods for the decomposition of chemical substances in the soil is monitored. However, the effectiveness of this method in the future to save the environment is debatable. Manuscript profile -

Ammonia enters the water from various sources such as industrial wastes, agricultural runoff, and decomposition of microorganisms living in water and as the final excreta resulting from the catabolism of proteins and amino acids in aquatic animals. Ammonia poisoning is associated with a wide range of symptoms due to the concentration of this substance. These symptoms can range from simple behavioral changes to severe neurological symptoms and death. Fish adopt different strategies when this poisoning occurs; these include reducing nutrition, reducing protein metabolism, detoxifying ammonia and turning it into less toxic substances. Almost all fish organs respond to ammonia poisoning, but organs such as the liver, gills, muscles, and brain play a more prominent role in the development of symptoms, condition control, and detoxification. Understanding the biochemical mechanisms of these organs in the face of ammonia toxicity and understanding the pathophysiology of this toxicity can help prevent or manage this poisoning if it occurs. Of course, not all fish species respond the same way to ammonia toxicity, and some species that are more resistant may be better breeding options. Manuscript profile -

The aim of this study was to evaluate the protective effect of fenugreek seed extract against carbon tetrachloride (CCl4)-induced hepatic toxicity in rats. A total of 48 male Wistar rats were randomly divided into eight groups. The normal control group was intact. The liver-injury control group received intraperitoneal injection of 50% CCl4 (1 ml/kg) twice a week for a total of 10 times. Normal experimental groups received fenugreek extract (50, 100 and 200 mg/kg intragastrically). Liver-injury experimental groups were administrated fenugreek extract (3 doses as above) along with CCl4. The rats were sacrificed on the 34th day, blood was withdrawn by cardiac puncture and the levels of ALT, AST, ALP, and GGT were measured. Administration of CCl4 significantly increased the levels of liver enzymes in the liver-injury control group in comparison to normal control (p < /em><0.001). Administration of fenugreek extract showed a significant tendency towards normalization of all measured biochemical parameters in CCl4-treated rats. These results demonstrate that fenugreek extract exerts protective effects against CCl4-induced damage in rat liver, and supports a potential therapeutic use of fenugreek as an alternative for patients with liver diseases.

A limited number of probiotics attach and or break down aflatoxins in foods and edible substances. The aim of this study was to investigate the effects of Lactobacillus acidophilus and Lactobacillus plantarum probiotics and their combinations on the removal of or coupling with aflatoxin M1 in yoghurt drink (Doogh). In this study, 72 treatment and control groups were prepared in three replicates. The groups were included four groups of bacterial L. acidophilus, L. plantarum, and a combination of them, and finally with a non-bacterial group as control (in general four groups). Doogh was prepared at different temperatures (4, 21 and 37 °C) was being before stored for 2, 11 and 30 days. The maximum level of aflatoxin degraded was done in industrial Doogh affected by L. acidophilus plus L. plantarum at all assigned temperatures and days. This maximum level was measured on the second day (100.00 ± 0.86), eleventh day (100.00 ± 1.27) and thirtieth day (100.00 ± 0.60). The results suggest a better food security in using industrial Doogh compared to traditional one. Manuscript profile -

This research was aimed to assess the ability of Lactobacillus rhamnosus strain GG in the reduction of aflatoxin B1 (AFB1) in a simulated human gastrointestinal tract containing sterilized milk. Materials & Methods: For this purpose, the bacterial count and aflatoxin concentration were adjusted to 1×1010 cfu/ml and 5 ppm, respectively, where artificial gastrointestinal tract discharges were inoculated in the simulated environment. In this study 6 treatment groups were assessed in the presence and absence of bacteria, sterilized milk, and gastrointestinal juice suspension. The concentration of residual aflatoxin was determined using high-performance liquid chromatography (HPLC) and purification by Immunoaffinity column. Results: The reduction of aflatoxin B1 at all treatments was determined using HPLC with a detection limit of 0.25 mg/ml and a quantification limit of 0.75 mg/ml. The mycotoxin recovery rate was between 89% and 94% for AFB1. The aflatoxin B1 calibration curve with a correlation coefficient of 0.95 was linear in the concentration range of 1 to 10 ng/ml. The highest and lowest average removal percentage of aflatoxin B1 was observed for 5 and 1 treatments (58.8 ± 0.018 and 13.86 ± 0.017) respectively, where a significant difference in removal percentage was observed among six treatment groups. Conclusion: The results indicated that beside L. rhamnosus strain GG, gastric and small intestine juices are suitable to eliminate or reduce aflatoxin B1, as well. Manuscript profile -

This research aimed to remove aflatoxin M1 using two probiotics, Bifidobacterium lactis and Streptococcus thermophilus, either alone or in combination, in skimmed milk containing this toxin. The study investigated the effects of storage time, microbial strain, bacterial concentration, toxin concentration, and temperature on the removal of aflatoxin M1. Two probiotic bacteria, Bifidobacterium lactis and Streptococcus thermophilus, at dilutions of 108 and 1010 CFU/ml, were inoculated alone and in combination into skimmed milk contaminated with different concentrations of aflatoxin M1 (0.1, 0.25, and 0.5 μg/ml). The samples were then incubated at 4°C and 37°C for 0.5, 1, 2, and 24 hours. The detoxification percentage of aflatoxin M1 was measured using high-performance liquid chromatography (HPLC). The results showed an increase in the removal of aflatoxin M1 with time. The removal of aflatoxin M1 by these strains varied from 12% to 87% depending on the concentration of bacteria, storage time, toxin concentration, and bacterial strain, whether alone or in combination. The results of this study suggest that using probiotics can be an effective method for reducing or eliminating the concentration of aflatoxin M1 in the dairy industry. Manuscript profile
