Summary: In this study, five novel dsRNA genomes were identified from four different Mucor hiemalis strains using next-generation sequencing (NGS). These genomes encode coat protein (CP) and RNA dependent RNA polymerase (RdRp), with unique translation mechanisms observed in different viruses. Analysis also revealed the evolutionary placement of these Mucor viruses based on specific motifs and frameshift mechanisms.

Summary: The release of untreated wastewater containing biotoxic heavy metals poses a significant environmental and health challenge, but microbial removal techniques offer a promising alternative. The study investigated detoxification mechanisms of nickel-resistant fungal strains, identified as Neurospora crassa and Aspergillus flavus, and identified optimal conditions for industrial exploitation. Findings suggest the potential for large-scale removal of nickel from waste generating industries through simultaneous mechanistic removal approaches.

Summary: In this study, the effects of Snf-ss subunit on the growth and lipid accumulation of M. circinelloides were analyzed and compared under different carbon nutrient signals. The results showed that the knockout of Snf-ss subunit resulted in significantly increased lipid accumulation, especially in response to xylose or mixed glucose and xylose. Furthermore, the transcriptional level of ACC1 was also affected by the deletion of Snf-ss subunit. This study provides insights into the regulation of lipid production in M. circinelloides and its potential application in lignocellulosic lipid production.

Summary: The removal of chlorpyrifos from the environment is of great interest due to its high toxicity and persistence. This study explores the use of biological strategies to remediate chlorpyrifos-contaminated soil, including assisted natural attenuation and bioaugmentation. Two soils were found to have the ability to degrade chlorpyrifos, and two CLP-degrading strains were isolated. Different strategies, such as biostimulation and bioavailability enhancement, were considered to increase the effectiveness of soil bioremediation. It was found that a combination of bioaugmentation and the use of a biodegradable compound yielded the best biodegradation results.

Summary: This study successfully isolated and screened fungal strains that can degrade pretilachlor, a highly toxic herbicide. The strains Aspergillus ficuum (AJN2) and Aspergillus sp. (PDF1) were able to degrade 79% and 73% of pretilachlor respectively. The immobilization technique was used to further enhance the degradation ability of the isolated strains, and the immobilized spores of AJN2 and PDF1 mineralized 84% and 95% of pretilachlor respectively. Enzymatic studies showed that AJN2 had high lignin peroxidase activity, while PDF1 had high manganese peroxidase activity. This study confirms the efficient degradation ability of Aspergillus ficuum (AJN2) towards pretilachlor.
