Summary: This study aimed to enhance the methanogenic activity of distillery wastewater with high potassium (K) content using a mesophilic three-stage upflow anaerobic sludge blanket (UASB). The three-stage UASB could not function properly at a chemical oxygen demand (COD) loading rate greater than 3 kg/m3d due to potassium toxicity. However, by diluting the wastewater to reach moderate K toxicity, the three-stage UASB was able to effectively function at high COD loading rates due to the development of adapted anaerobe communities.

Summary: The direct disposal of distillery sludge in water streams creates a major environmental problem. This study found that mixing distillery sludge and bio-compost with coal samples in a specific ratio can serve as an efficient alternative fuel source. The pyrolysis and gasification processes produced high-quality char, bio-oil, and syngas, with the highest hydrogen gas production among all other substrates. This method has the potential to reduce dependency on traditional non-renewable fuel sources.

Summary: Food preservation is a method used to slow down food spoilage and reduce the risk of foodborne illness. Researchers are increasingly focusing on biopreservation techniques, which utilize lactic acid bacteria and their antimicrobial substances to extend shelf life and maintain nutritional value. Enterococcus, a type of lactic acid bacteria, produces a bacteriocin called enterocin that inhibits the growth of pathogenic bacteria. This report highlights the application of Enterococcus in biopreservation of meat and meat-based products, as well as the effects of enzymes, temperature, and pH on the stability of bacteriocin. Industry procedures for meat preservation are also discussed, including their benefits and drawbacks.

Summary: The uncontrolled use of pesticides poses a severe threat to soil and plant-associated microbiome, emphasizing the importance of finding an environmentally friendly alternative to enhance plant productivity. Endophytic microorganisms with multi-plant beneficial mechanisms play a vital role in protecting plants from biotic and abiotic stress factors. The study on the pesticide tolerating and alleviating effect of endophytic Bacillus sp. Fcl1 in quinalphos-induced plant toxicity suggests the potential application of microbial bioinoculants for field usage even in the presence of pesticide residues.

Summary: The genotypic and phenotypic toxicity of two strains of Enterococcus faecalis and Enterococcus faecium isolated from kimchi were evaluated in this study. The strains were tested for their genotypic toxicity through whole-genome sequencing and their phenotypic virulence, including susceptibility to antibiotics and enzymatic activities. The in vivo toxicity of the strains was evaluated using an acute oral administration test in rats. The results showed that both strains were safe, without antibiotic resistance or virulence factors, and had a high survival rate in gastrointestinal conditions. Therefore, these strains could potentially be used as probiotics in food.

Summary: Two new glycosylated and succinylated macrocyclic lactones, succinyl glyco-oxydifficidin (1) and succinyl macrolactin O (2), were isolated from a Bacillus strain collected from an intertidal mudflat on Anmyeon Island in Korea. Their planar structures were proposed using mass spectrometric analysis and NMR spectroscopic data, while the absolute configurations were determined through various methods. Biological evaluation showed that both compounds have potential therapeutic effects in inhibiting and dissociating amyloid beta (A beta) aggregation.

Summary: The COVID-19 pandemic has caused a significant increase in plastic waste, such as disposable gloves, masks, tissues, and other PPE. Improper management of healthcare waste poses serious health hazards and challenges for solid waste management authorities. The incineration of COVID-19 medical waste generates microplastic particles, dioxins, furans, and toxic metals, which pose a threat to human and animal health. Degradation of microplastics by microorganisms can be a sustainable solution to mitigate the microplastic pollution caused by the pandemic.

Summary: Phosphorous is an essential macronutrient that actively participates in various metabolic and regulatory activities of animals and humans. However, phytic acid, a known antinutritional substance, has a strong affinity for essential mineral ions and can reduce the bioavailability of phosphorous. Bacterial phytases have been identified as potential solutions for efficient utilization of soil phytate and sustainable phosphorous management. This review explores the applications of bacterial phytases in biofertilizers, phosphorus acquisition, and plant growth promotion, and discusses fermentation-based strategies and future trends.
