Summary: This study investigated the potential of a combined method of phytoremediation and bioaugmentation for pentachlorophenol removal in secondary treated wastewater. The results showed that the selected fungal isolate, identified as Penicillium Ilerdanum, displayed a significant capacity for PCP tolerance and elimination. The phytoremediation treatment using Polypogon maritimus and Lemna minor also showed a high efficiency in PCP removal.

Summary: A cellulose-degrading anaerobic bacterium Paracoccus sp. Strain LZ-G1 was isolated from cow dung, capable of degrading cellulose and adsorbing Cd2+. Bioaugmentation with this strain in an AD system significantly increased biogas and methane production from HM-containing plant residues and cow manure. Restoration of the microbial community by LZ-G1 bioaugmentation improved biogas yield and methane production rate during the AD process.

Summary: The uncontrolled use of chemicals, urban wastes, nuclear resources, mining, petrochemicals and disposal of sewage sludge have led to rapid industrialization and severe heavy metal contamination of soils and waterways. Both inorganic and organic pollutants can impact the composition and functionality of soils, posing a threat to food security and human health. Remediation, such as Enhanced Natural Attenuation (RENA), using natural products from plants or microbes, is necessary to detoxify the environment and restore its productivity. This review discusses the technology, microbes, mechanism, challenges, and recommendations associated with RENA for a sustainable environment.

Summary: This paper integrates biological research and evaluation methods to study the bioremediation of saline soils, including processes of using organisms to deal with salt and using statistical models to verify results. The cooperation between plant growth-promoting bacteria and halotolerant plants is emphasized, as well as the physiological characteristics of plants during saline stress and ion mobility.

Summary: This study reviewed the research on enhanced constructed wetlands (CWs) for the removal of heavy metals and metalloids (HMMs) from polluted water. A bibliometric analysis was performed to evaluate research trends, critical literature, and keyword evolution. The study found that research on CW technology for the remediation of HMM-polluted water is receiving increased attention, with no apparent trends in topics. Suggestions for optimizing the design and operation of efficient CWs for HMM-polluted water treatment are proposed based on the established literature.

Summary: Soil pollution from petroleum hydrocarbon is a global environmental problem that requires the development of new approaches and the improvement of existing techniques. Biochar, a low-cost carbonaceous product, has gained relevance in soil remediation. The co-application of biochar with other bioremediation techniques and modifying biochar properties before use can enhance its effectiveness in petroleum hydrocarbon remediation.

Summary: With the development of industries and excessive use of petroleum compounds, petroleum pollution has become a serious threat to the environment. This study aimed to investigate the effect of phytoremediation and bioaugmentation on the biological activities of soil contaminated by petroleum. The results showed that sorghum and bermudagrass were more tolerant to petroleum toxicity compared to barley, and the bacteria had a greater positive effect on the dry weight of polluted soil compared to non-polluted soil. Plants had a higher ability to degrade total petroleum hydrocarbon (TPH), while bacteria were better at degrading polyaromatic hydrocarbons (PAHs).

Summary: This study investigated the effects of fertilizer application on the remediation potential of co-plantings of Salix interior Rowlee and Festuca arundinacea Schreb. in wood preservative-contaminated soil. The results showed that a 1:1 nitrogen-to-phosphorus ratio treatment yielded the best results in terms of metal(loid) uptake and contaminant and nutrient leaching, with increased arsenic and copper uptake in the plant roots. High arsenic and copper amounts were found in both Salix and Festuca in specific nitrogen-to-phosphorus ratio treatments.

Summary: The aim of this study was to remove pentachlorophenol from wastewater using combined bio-processes, a novel isolate, and Typha angustifolia. The results showed that the fungal isolate was able to remove pentachlorophenol in liquid mineral medium, and the combined bio-process of bioaugmentation and phytoremediation further increased the removal efficiency. Additionally, the use of Typha angustifolia also contributed to the removal of pentachlorophenol.

Summary: The present research investigated the influence of inoculating indigenous filamentous fungi on Alocasia calidora growth attributes and biochemical responses, as well as the tolerance, uptake, and translocation of multiple metals under multi-metal contamination. The results showed that soil enzyme activity increased and plant growth was enhanced through improved chlorophyll and carotenoid production. Additionally, the inoculated A. calidora exhibited higher accumulation of various metals in shoots and roots compared to the control plants, indicating the potential of fungal inoculation as an effective strategy for metal removal from polluted soils.
