“…In some cases, the total abundance of soil bacteria in vineyard soil was on an average 260% higher under herbicide application than under mechanical weeding (Mandl K et al 2018). Penoxsulam, a sulfonylurea herbicide, has been reported to show toxicity against no-target organisms and soil bacterial population (Sondhia S et al 2016;Rajuput S et al 2016). Another study reported a considerable reduction in the abundance of Ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in 5.0 mg/kg mesotrione-treated soil (Du ZK et al 2018).…”

Background: The growth of weed is common problem in rice cropping, leading to the application of herbicidal substances to suppress weed growth. Weed biocontrol through novel bioorganic fertilizer (BIO) has been established in rice cultivation, however, its main herbicidal components and influence on soil bacterial community are unknown.Results: We identified three herbicidal components, hexadecanoic, isovaleric, and 2-methylbutyric acids, in BIO extract. We conducted 16S rRNA sequencing to identify changes in soil bacterial community in response to BIO treatments and performed a RDA analysis with soil chemical properties and weed-control effect. The OTU, Chao1 and Shannon indices did not differ substantially among the BIO treatments, and the bacterial diversity was not significantly affected by BIO. As result from PCA analysis, we discovered that soil bacterial community was not significantly influenced by BIO. We identified six dominant phyla (Proteobacteria, Acidobacteria, Chloroflexi, Nitrospirae, and Verrucomicrobia) in BIO-treated paddies. The five most abundant genera were Anaeromyxobacter, Candidatus Nitrosotalea, Clostridum sensustricto1, Haliangium and Candidatus Nitrotoga. From the RDA analysis, the highest correlations were obtained for soil pH, total K, and Pseudomonas. The weed-control effect mostly correlated with the abundance of Candidatus Koribacter, Clostridium sebsustricto 9, and Nonomuraea. Rice yield had a distinct relationship with Nonomuraea, Nitrospira, and Candidatus Koribacter.Conclusions: With the changes in soil pH and total K, BIO could impact bacterial communities and weed control, and in turn affect rice yield. This foundation can be helpful that application BIO is a “not harmful” and feasibility weed biocontrol strategy.

“…Many strains have proven to be very effective as bioremediation agents and have displayed excellent degrading efficiencies. For example, AF and AN have been reported to efficiently dissipate herbicide penoxsulam [37]. Similarly, herbicide metachlor and chlorpyrifos are also reported to be degraded by AFu [38,39].…”

The current research is a pioneer in the evaluation of isopyrazam biodegradation, which has been performed utilizing soil‐isolated microbes. Biodisintegrative assays of pure fungal strains, namely Aspergillus flavus (AF), Penicillium chrysogenum (PC), Aspergillus niger (AN), Aspergillus terreus (AT), and Aspergillus fumigatus (AFu), and bacterial strains, namely Xanthomonas axonopodis (XA) and Pseudomonas syringae (PS), were utilized. Initial isopyrazam concentration (10 mg/L) was prepared with an individual microbial suspension and monitored for 35 days. Isopyrazam biotransformation was analyzed quantitatively and qualitatively by UV–visible spectrophotometery and gas chromatography–mass spectroscopy. P. syringae (R2 = 0.90) and X. axonopodis (R2 = 0.88) displayed maximal potential to metabolize the fungicide (86% and 80%, respectively) while forming intermediate metabolites, including 3‐difluoromethyl‐1‐methyl‐1H‐pyrazole‐4‐carboxylic acid ((S)‐9‐hydroxy‐9‐isopropyl‐1,2,3,4‐tetrahydro‐1,4‐methanonaphthalen‐5‐yl)‐amide, 3‐difluoromethyl‐1H‐pyrazole‐4‐carboxylic acid, and 3‐difluoromethyl‐1‐methyl‐1H‐pyrazole‐4‐amide. Isopyrazam degradation by all strains, AT, PC, AFu, AN, AF, XA, and PS, was found to be 11%, 18%, 21%, 21%, 18%, 30%, 80%, and 86%, respectively, after 35 days, elucidating the effectiveness of all the utilized strains in degrading isopyrazam at varying rates. The descending order of half‐lives (days) obtained is as follows: AT (56.8) > PC (44.7) > AFu (40.7) > AN (39.6) > AF (32.6) > XA (28.1) > PS (21) days. Current research can influence imperative and significant environment‐friendly bioremedial strategies for xenobiotic eradication from the ecological compartments.

“…In the present study, fungal strains isolated from soil samples belonged to the genera Aspergillus, Penicillium and Trichoderma. These fungi were the more prevalent in soil samples from previous studies (Oliveira et al, 2013;Hamed, 2013;Zhang et al, 2014;Iqbal and Utara, 2015;Mirhendi et al, 2016;Sondhia et al, 2016) and are also Evaluation of carbon, nitrogen and phosphorus sources for the production of glucose oxidase. The use of carbon sources (glucose, sucrose, maltose, xylose, galactose and lactose), nitrogen sources (peptone from meat, maltose extract, soy peptone, yeast extract and KNO3) and phosphorus sources (KH3PO4 Na2HPO4 and P4O10) as substrates for the production of glucose oxidase was investigated using a bioprocess with the isolated A. niger LMM01 strain.…”

Glucose oxidase (GOx) has several industrial applications. It is believed that there are several species of fungi that have the ability to produce this enzyme, most of which are unexplored. This work aimed to investigate the production of glucose oxidase (EC 1.1.3.4) by fungi isolated from soil samples of the Amazonian forest. Filamentous fungi were isolated from soil samples from the Adolpho Ducke Forest Reserve, located in Manaus, Amazonas. Strains were subjected to submerged bioprocessing to select for the best GOx producers. Those selected for the production of isolated enzymes were subjected to kinetic tests that evaluated production of the enzyme and consumption of the biomass substrate by the isolates. In addition, experiments to evaluate the optimal carbon, nitrogen and phosphorus sources as well as the influence of the bioprocess factors were carried out. Finally, GOx production was investigated in a semi-continuous system for 7 days. The most frequent isolates isolated from soil samples belonged to the genera Aspergillus, Penicillium and Trichoderma. Aspergillus niger LMM01 was the best GOx producer. Glucose, peptone and KH 2 PO 4 were demonstrated to be the optimal carbon, nitrogen and phosphorus sources, respectively. Multivariate experiments demonstrated that the parameters with the greatest effect on GOx production were pH and agitation. Stable expression results for GOx (7.74 U/ml) were obtained over 7 days in a semi-continuous process. In this context, the new Amazonian source of this enzyme (A. niger LMM01), and enzyme production in a semi-continuous process, demonstrates the importance of the present work.
