“…For this reason, it is important to assess the effects of environmental pollution, especially that generated by sewage, on organisms, specifically with regard to toxicology. The Allium cepa L. has been widely used as a bioindicator organism in experiments (Egito et al, 2007;Abreu-Junior et al, 2019), as its roots grow quickly and it is quite sensitive to environmental changes, making its results comparable to those obtained with prokaryotes, lymphocytes test systems and ames test (Cabuga et al, 2017;Klauck et al, 2017;Fatma et al, 2018). The Artemia salina L. is also an organism widely used to assess toxicity levels, since it is highly sensitive and provides biological responses in a relatively short time (Villarroel et al, 2003), besides having a good correlation with in vivo acute oral toxicity tests (Silva et al, 2010).…”

Abstract Whereas the effects of the substances found in domestic sewage on live organisms is important to evaluate the use of plants to remove pollutants from the environment. The objective of this study was to assess the phytoremediation activity of Allium cepa L. (onion) roots exposed to raw sewage, as well as the acute toxic activity of this effluent for the bioindicators A. cepa, through a cytotoxicity test, and Artemia salina L., through a mortality/immobility test. The physicochemical assessments of the sewage were conducted in two scenarios: immediately after collection and after being in contact with onion roots (phytoremediation) for 24 hours. The physicochemical data indicate there was a reduction in nitrogen and phosphorus levels and in biochemical oxygen demand in sewage treated. The results from the cytotoxicity test with A. cepa indicated a reduction in the mitotic cell divisions of the onions treated with the raw sewage. The mortality/immobility test with A. salina indicated that the concentrations with 50 and 100% of raw sewage induced the mortality of the nauplii. Thus, the data suggest new studies that seek greater efficiency, efficacy and viability of onion phytoremediation.

“…Mancozeb is one of the contact fungicides of the ditiocarbamate group that has been used for more than 50 years in agriculture (Szolar 2007;Fatma et al 2017). This fungicide consists of 20% manganese with 2.5% zinc salts and it is widely used to control fungal diseases such as leaf spots, downy mildew, and blossom end-rot on vegetables and fruit plants (Worthing 1991;Cernohlavkova 2008;Brody et al 2013).…”

Mancozeb is a group member of dithiocarbamat fungicides that most widely applied in the field. The use of mancozeb causes residues that have negative effects on agricultural production system and on agricultural environment. This research aimed to obtain dark septate endophyte (DSE) fungal isolates that are tolerant to mancozeb fungicide. The study was consisted of three steps, i.e., the isolation of DSE fungi from chili roots, the effect of DSE fungal isolates on chili seeds, and the growth ability of DSE isolates on medium supplemented with mancozeb. Thirteen DSE fungal isolates were isolated from chilli pepper roots and grown in the field assumed to be contaminated by pesticides. The isolates of DSE fungi caused the growth of chili seeds were normal and abnormal. Seven DSE isolates were able to grow well at PDA medium suplemented with mancozeb at concentrations of 100, 200, 400, and 800 ppm with different levels of relative growth inhibition. Mancozeb on PDA medium influenced the mycelial growth and colony color of DSE fungal isolates. The biomass of DSE fungal isolates were reduced when they were grown at malt extract broth (MEB) medium suplemented various levels of mancozeb. ABSTRAKMankozeb adalah kelompok fungisida ditiokarbamat yang paling banyak digunakan di lapangan. Penggunaan mankozeb yang tidak sesuai dapat menyebabkan dampak negatif pada sistem produksi dan lingkungan pertanian. Penelitian ini bertujuan untuk memeroleh isolat cendawan Dark Septate Endophyte (DSE) yang toleran terhadap fungisida berbahan aktif mankozeb. Penelitian terdiri atas tiga tahap, yaitu isolasi cendawan DSE dari akar tanaman cabai, pertumbuhan isolat cendawan DSE pada tanaman cabai, dan kemampuan tumbuh cendawan DSE pada media yang mengandung mankozeb. Berdasarkan hasil penelitian diperoleh 13 isolat cendawan DSE dari akar tanaman sawit yang terkontaminasi oleh penggunaan pestisida. Isolat cendawan DSE yang diperoleh menyebabkan pertumbuhan benih cabai normal dan tidak normal. Tujuh isolat cendawan DSE mampu tumbuh dengan baik pada media PDA yang telah diberi penambahan konsentrasi mankozeb, yaitu 100, 200, 400, dan 800 ppm dengan hambatan pertumbuhan relatif yang berbeda. Penambahan mankozeb pada media PDA memengaruhi pertumbuhan miselium dan warna koloni isolat cendawan DSE. Pertumbuhan cendawan DSE pada media cair Malt Extract (ME) yang ditambahkan konsentrasi mankozeb menyebabkan penurunan biomassa cendawan DSE. Kata kunci: ditiokarbamat, hambatan pertumbuhan relatif, toleran

“…Subsequently, β-glucosidases chop cellobiose to release glucose molecules. Further, during the hydrolysis reaction, the endoglucanases act on the amorphous region, which is the more soluble portion of the cellulose structure; meanwhile, cellobiohydrolases cleave β−1,4-glycosidic bonds from the chain ends (Srivastava et al, 2018).…”

“…The test with A. salina is a method that has a good correlation with acute oral toxicity tests in vivo (Silva et al, 2010). Similarly, the test with A. cepa could be sensitive, and in addition has a positive correlation in prokaryotes and eukaryotes (Fatma et al, 2018), being indicative of risk to human health or the environment.…”

With the goal of assessing possible impacts of fish farming in great-volume cage systems on the water quality of a reservoir, the authors provided abiotic data from 72 samples obtained before and after farming site implementation. The figure shows the principal components analysis results for seven limnological variables. The highest dissolved oxygen (OD) concentrations were observed before the fish farm became operational. During the post-production period, the highest phosphorous (PT) and ammonium (NH4) concentrations were observed as well as high conductivity and turbidity values. Authors concluded that fish farming in cage systems located in Solteira Island Reservoir, Brazil, caused significant temporal and sudden spatial changes in water physical and chemical variables.
