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.

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.

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.

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 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.

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.

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.
