AbstractRelease of complex waste in environment due to massive industrialization is a major threat globally. Anthracene is a polycyclic aromatic hydrocarbon generally released as a waste from petrochemical industries. It may bioaccumulate in food chain which results into nephrotoxicity in humans. Thus, there is a necessity to clean up the contaminated site efficiently. Bioremediation is ecofriendly technique for waste reclamation however it consumes more time. Thus, nanotechnology has exploded with unique properties of nanomaterials. Bio-based nanoparticles (NPs) synthesis is a recent and agro ecologically friendly approach for remediating environmental waste. For the first time present study reports Fusarium proliferatum WC416 isolated from refinery effluent for the synthesis of zinc oxide nanoparticles (ZnO NPs). Moreover, biosynthesized ZnO NPs used for their photocatalytic efficiency to remove anthracene at varying concentration. During synthesis of ZnO in aqueous medium showed a characteristic peak at 365 nm as analyzed by Ultraviolet–visible spectrum. The formation of NPs was further confirmed by Fourier transform infrared spectroscopy (FTIR), transmission electron microscope (TEM), and energy-dispersive x-ray (XRD). Morphologically the synthesized ZnO NPs were found to be in irregular polygonal shapes. Moreover, ZnO NPs showed photocatalytic activity for removal of anthracene upto 65 ± 0.03%, p value = 0.00032 at 100 ppm followed by 50.7% ± 0.02%, p value = 0.00023 at 250 ppm and 40.83 ± 0.03%, p value = 0.00042 at 500 ppm within 6 hr duration. Anthracene transformation during photocatlytic activity was confirmed by GC MS analysis, and the products were detected as 1,2 benzene carboxylic acid (m/z 166) and salicylic acid (m/z 138). Phytotoxicity effect of synthesized ZnO NPs on seed germination index of Phaseolus moonga and Vigina radiata was also studied to promote sustainable and biocompatible nano-agriculture.Keywords: AnthraceneF. proliferatum WC416fungal synthesiszinc oxide nanoparticles (ZnO NPs) AcknowledgementThe author is thankful to School of Environment and Sustainable development, Central University of Gujarat for providing research facilities.Author contributionsAll authors contributed to the research conception and design.

AbstractPhosphorus (P) availability in soil is often limited, posing a challenge for sustainable agricultural production. Phosphate solubilizing microorganisms (PSMs) have emerged as a promising biological approach to enhance soil P availability while minimize negative environmental impacts. Exploring the impact of PSMs on increasing soil available P is crucial for optimizing the utilization of insoluble P in soil and promoting sustainable agricultural practices. In this article, we provide a comprehensive review on the dynamics of soil available P, including its input, loss and transformation processes. Additionally, we draw a conclusion about how PSMs increase the availability of P in soil, including solubilizing inorganic P (Pi) and organic P (Po) by secreting substances such as protons, organic acids, inorganic acids, exopolysaccharides, hydrogen sulfide, siderophores and phosphatases. Notably, the factors influencing the P solubilizing activity of PSMs in soil are thoroughly discussed. Moreover, practical applications of PSMs for increasing soil P availability are summarized. Future research should focus on exploring novel PSM isolates, conducting long-term field experiments to assess the effects and potential risk of PSMs under diverse conditions, and investigating synergistic approaches with other P activators or beneficial microorganisms. This review will advance our understanding of PSMs and their practical application, enabling their widespread adoption in agricultural systems.Keywords: Potential riskpractical applicationsustainable agricultural production Author contributionsFeng Liu: Writing-original draft preparation.

AbstractThe increasing accumulation of heavy metals (HMs) due to various human activities is a significant concern. This study has employed 16S rRNA amplicon sequencing and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) spectrometry to investigate HMS concentrations and identify bacterial strains exhibiting resistance to HMS, and used the PICRUSt tool to assess the metabolic pathways of bacterial communities. Our primary focus was to assess HMs concentrations in the soils of Baghdad (BG) and the Baiji Oil Refinery (BOR) area while examining the bacterial diversity in these regions. The results revealed that the average levels of Cadmium (Cd) and Lead (Pb) in BOR were higher than in BG and the global average. In BOR, the most prevalent bacterial genera were Flavobacterium, Shewanella, and Pseudomonas. Using the PICRUSt tool, we identified that Cd and Pb substantially impacted the metabolic pathways of these bacterial communities. This study marks the first report in Iraq to employ 16S rRNA gene sequencing to analyze bacterial communities in Iraqi soil and investigate how HMs affect them. However, this study can serve as a reference for future research and the development of innovative strategies for the sustainable management of soil ecosystems.Keywords: Baiji oil refineryenvironmental assessmentheavy metal contaminationmetabolic pathwaysmetagenomics Disclosure statementNo potential conflict of interest was reported by the author(s).

AbstractDue to the obvious potential hazards it poses to the environment, animals, and human health, Mn (II) contamination has become worrisome. The broad aim of the study was to examine the contamination levels of soil in the Shivrajpur Mn mine site, physicochemical tests such as pH and heavy metal analyses were done. Later 16S rRNA sequencing was used to characterize bacterial species isolated from different colonizer plant samples. The bacterial strains recovered from Mn mine rhizospheric soil exemplified morphological and molecular diversity. It was discovered that all seven bacterial isolates could survive Mn salt concentrations up to 2000 mg/l, whereas only one, Staphylococcus capitis (GenBank OP861008), could withstand concentrations up to 10,000 mg/l. The three isolates, Staphylococcus capitis, Bacillus albus (GenBank OP861099), Bacillus tequilensis (GenBank OQ135205), have the ability to sustain the Mn tolerance as the agar wells were surrounded by growth expanse. The findings imply that the Staphylococcus capitis could be used to create a biosorbent that is both effective and environmentally benign, and it can aid in the bioremediation of contaminated soil.Keywords: BacteriabioremediationMn contaminationmolecular diversity16SrRNA sequencing AcknowledgementsWe are grateful to Prof. Kauresh Vachhrajani, Former Head and Professor of Zoology, The Maharaja Sayajirao University of Baroda for his vision and guiding force for taking up this initiative.

AbstractThe increase in population has resulted in a rapid increase in waste that is being dumped within the environment. The addition of various harmful and contaminating compounds results in the degradation of the environment and has a direct impact on human health. Various research studies that are taking place in recent times help in the enhancement of the naturally available microbes to degrade toxic compounds that are liberated into the environment. Although various types of bioremediation techniques are available, microbe-associated remediation is proven to be the best option due to its effectiveness, no generation of toxic by-products, and natural availability of microbes with the ability to take up nutrients from the toxic contaminants that exist on the surface of the earth. Both ex situ and in situ bioremediation can be accomplished with the help of these microbes. In most cases, this is done through biofilm-assisted seclusion of pollutants, more precisely by means of extracellular polymeric substances (EPSs) of biofilm matrix. In recent times, various types of techniques have been implemented like proteomics, genomics, fluxomics and transcriptomics for bringing about maximum remediation by the microbial species. In order to explore the different kinds of microbial communities involved in natural bioremediation, the strategic approach of metagenomic analysis is adopted, which has brought about a technological drift in remediation, even at a genomic level. As chemical mode of remediating wastes are associated with the release of various harmful chemicals those can be toxic to the environment, the use of biological systems can be a potential agent in the conversion of complex waste materials to simpler substances so that it mixes with the environment in easier manner. Microbes are the potential entities that can easily act on the waste materials and bring about remediation in an effective manner.Keywords: Biofilmbioremediationmicrobesomicsorganic wastepollutant Disclosure statementNo potential conflict of interest was reported by the author(s).

AbstractTufa is a common calcium carbonate deposit in karst landscapes and microbes may play an important role in its formation. As an important natural resource treasure trove, the diversity of bacteria from the Jiuzhaigou National Nature Reserve tufa deposits and their potential to deposit carbonates are still unknown. In this study, 16S rRNA gene sequencing technology was used to assess the bacterial community composition of Pearl Shoal in Jiuzhaigou National Nature Reserve. The results showed that the main dominant phyla were Proteobacteria, Cyanobacteria, Bacteroidetes and Actinobacteria. With the gradual increase of flow rate, the bacterial community structure was gradually simplified and the dominant phylum changed. The community structure of different sampling sites was significantly different. Besides, 17 strains capable of precipitating calcium carbonate were isolated using microbiological methods. The two strains with relatively strong calcium-forming properties were identified as Leucobacter sp. (J1) and Brucella sp. (J2), respectively. Both strains were able to elevate the environmental pH and produce extracellular polymeric substance (EPS). However, Leucobacter sp. (J1) formed calcite crystals with spherical structure, whereas Brucella sp. (J2) formed the rhombohedral and some spherical calcite crystals, evidence for strain-specific characteristics. It is the first research to provide information regarding the diversity of bacterial communities associated with tufa deposits and the characterization of calcifying bacteria isolated from Jiuzhaigou National Nature Reserve.Keywords: Calcifying strainshigh-throughput sequencingJiuzhaigou National Nature ReserveTufa Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis work was supported by the Specialized Fund for Ecological Restoration of Jiuzhaigou [N51322112022000246].

AbstractInsecticides are widely used in agriculture, horticulture, medicine, and industry, as well as domestically. Increased insecticide application has been attributed to higher agricultural productivity and lower infield and postharvest crop loss in the twentieth century. Malathion is a very commonly used organophosphorus (OP) insecticide applied in over 100 food crops in agriculture and post-harvest storage. Different species of Aspergillus have shown their efficiency to degrade OP chemicals. A malathion tolerant Aspergillus niger MRU01, developed by prolonged malathion exposure, was tested for its efficiency to remove malathion as well as three other commonly used OP insecticides, viz., parathion, chlorpyrifos and dimethoate. The tolerant strain showed growth efficiency as well as enhanced production of phosphatases and esterase enzyme as compared to untreated and treated wild type (A. niger ATCC16404). The removal of malathion was 29% and 68%, in the wild type and the tolerant strain, respectively during five days. The tolerant strain was also able to remove dimethoate (63%) and chlorpyrifos (54%) with high efficiency while a low rate of removal of parathion (33%) was observed. The strain can be tested in the microcosms more specifically for bioremediation of other OP insecticides before its application in the field.HIGHLIGHTSThe malathion tolerant Aspergillus niger MRU01 grew efficiently in the presence of 500 μM malathion.Treatment of the fungus with malathion and other OP insecticides – parathion, chlorpyrifos, and dimethoate – caused enhanced expression of phosphatases and esterases.The tolerant A. niger MRU01 strain had significantly lower mycelia concentrations of insecticides than of the wild type A. niger ATCC16404.Degradation of insecticides by the tolerant strain was significantly higher than by the wild type indicating its broad spectrum of tolerance.Keywords: Aspergillus nigermalathion mutantOP insecticidesesterasesphosphatasesremoval AcknowledgmentsThe research was partly funded by Department of Science and Technology, Government of Odisha, and OHEPEE, Government of Odisha.

摘要农药广泛应用于农业、园艺、医药、工业和家庭。杀虫剂使用量的增加归因于20世纪农业生产力的提高和田间和收获后作物损失的减少。马拉硫磷是一种非常常用的有机磷杀虫剂,应用于农业和收获后储存的100多种粮食作物中。不同种类的曲霉已经显示出它们对OP化学物质的降解效率。通过长期接触马拉硫磷而培育出的耐马拉硫磷黑曲霉MRU01,对其去除马拉硫磷以及其他三种常用的有机磷杀虫剂(对硫磷、毒死蜱和乐果)的效率进行了测试。与未经处理和处理的野生型(A. niger ATCC16404)相比,该耐药菌株表现出生长效率,并提高了磷酸酶和酯酶的产量。野生型和耐受性菌株在5 d内对马拉硫磷的去除率分别为29%和68%。耐药菌株对乐果(63%)和毒死蜱(54%)的去除率较高,对硫磷(33%)的去除率较低。该菌株在野外应用前可在微生物中进行更特异性的生物修复试验,以便对其他有机磷杀虫剂进行生物修复。耐马拉硫磷黑曲霉MRU01在500 μM马拉硫磷环境下生长良好。用马拉硫磷和其他有机磷杀虫剂(对硫磷、毒死蜱和乐果)处理真菌可增强其磷酸酶和酯酶的表达。耐药菌株MRU01菌丝体杀虫剂浓度显著低于野生型菌株ATCC16404。耐受性菌株对杀虫剂的降解率明显高于野生型,表明其耐受性谱广。本研究由奥里萨邦政府科技部和奥里萨邦政府OHEPEE部分资助。感谢印度政府DST在DST- first方案下提供的基础设施赠款。作者的贡献所有作者都对研究的构思和设计做出了贡献。概念化,调查,原稿由Debasish Mohapatra完成。数据管理、形式分析由Sakti Kanta Rath完成,项目管理、数据分析、审查和编辑由Pradipta K Mohapatra完成。所有作者都阅读并认可了最终的手稿。”披露声明作者未报告潜在的利益冲突。这项工作得到了奥里萨邦政府科技部和奥里萨邦政府OHEPEE的支持。印度政府在DST- first下的DST基础设施拨款
