Summary: Rhodococcus equi ATCC13557 was found to have the potential to degrade E2 through two possible metabolic pathways, with homologous gene sequences for enzymes involved in estrogen degradation identified in its genome. Additionally, it also has the ability to potentially metabolize other steroid hormones such as cholesterol.

Summary: Antibiotics are widespread in soil, influencing bacteria involved in pollutant removal systems. Exposure to antibiotics can lead to dormancy in bacteria, affecting their degradative activity. The study found that antibiotic exposure inhibits DNA replication, triggering DNA repair in dormant cells for survival.

Summary: A novel bacterium Rhodococcus sp. CX-1 was isolated from contaminated soil, capable of efficiently degrading carbendazim as its sole source of carbon and energy. The degradation rate of carbendazim was highest at 40 degrees C and pH 7.0 for strain CX-1. Transcriptome analysis predicted two different pathways for carbendazim degradation.

Summary: It was found that Rhodococcus biphenylivorans TG9 enters a viable but nonculturable (VBNC) state under anaerobic conditions, leading to a significant reduction in metabolic activity and degradation ability. However, resuscitation by providing oxygen can restore the degrading capacity of TG9 in the VBNC state, providing a new strategy to cope with survival under anaerobic conditions.

Summary: Plant-based products such as essential oils and extracts have been widely used and produced in large quantities, potentially reaching the environment. Recent research has focused on the toxic effects of these products on non-target organisms, particularly in aquatic environments. While some products showed no toxicity or only at high concentrations, others were found to be toxic at very low levels, emphasizing the need for further standardized research in this area.

Summary: Lignocellulosic crop residues (LCCRs) are important biomass resources globally, but the burning of a massive amount of LCCRs results in environmental pollution. The use of lignocellulose degrading micro-organisms (LCDMOs) has emerged as an eco-friendly and effective way to dispose of LCCRs, improving soil properties, recycling plant nutrients, and promoting plant growth. A review discussing the potential of LCDMOs, factors affecting degradation rate, and future research areas for better understanding of these decomposers is critical.

Summary: By 2030, the European Commission aims to cut chemical pesticide use and risks in half. Essential oils (EOs) have been studied as potential substitutes for nematicides, which are chemical agents used to control parasitic roundworms in agriculture. However, there is still a lack of information on which EOs have been used on different nematodes and how they have been applied. This study provides an overview of available reports and data, exploring the extent of EO testing on nematodes and identifying the most commonly used EOs and formulations.

Summary: Petroleum pollution causes severe ecological damage, however, anaerobic microbial petroleum-degrading biotechnology is cost-effective, eco-friendly, and less hazardous, attracting extensive attention. Anaerobic oil-degrading bacteria such as sulfate-reducing bacteria, denitrifying bacteria have shown promising remediation effects in coastal areas, requiring a complete theoretical basis for efficient and environmentally-friendly use in the future.

Summary: This study aims to analyze the research on hydrocarbon-degrading bacteria in Colombia. A literature search yielded 37 relevant articles, with the highest number of publications in 2018. The most frequently identified bacterial genera were Pseudomonas and Bacillus, and some studies suggested that bacterial consortia are more efficient in hydrocarbon degradation compared to pure cultures.

Summary: This study investigates the relationship between dormancy and biodegradation in the environmental bacterium Rhodococcus biphenylivorans TG9. The research reveals the potential of Rhodococcus for degradation and dormancy, and demonstrates the ability of TG9 to degrade organic pollutants and exhibit differences in morphology and activity during dormancy state. These findings contribute to a better understanding of the genus Rhodococcus and its role in biodegradation under environmental stress.

Summary: This study examined the effectiveness of five plant essential oils (PEOs) in controlling Tuta absoluta and their impact on the predator Nesidiocoris tenuis. The PEOs from Achillea millefolium and Allium sativum significantly reduced the infestation by T. absoluta and did not affect the reproduction of N. tenuis. In addition, the spraying of A. millefolium and A. sativum triggered the release of herbivory-induced plant volatiles, which can act as messengers in tritrophic interactions.

Summary: The Green Revolution significantly increased crop productivity, but the excessive use of synthetic agrochemicals raised concerns about sustainability. Plant-based biopesticides, particularly plant essential oils (PEOs) and their active components, are being widely explored due to their ecofriendliness and safety. This review provides information on the applications and mechanisms of PEO-based biopesticides, as well as the challenges they face.

Summary: This study developed bio-based dispersants by mixing anionic biosurfactant with nonionic oleochemical surfactant for enhanced petroleum mobilization. The formulated dispersants showed high dispersion efficiency for bunker fuels A and C. The application of bio-based dispersants in water sources was optimized by Box-Behnken design, indicating a potential for improved oil spill remediation.

Summary: This study explored the arsenic speciation, abundance of arsenite-oxidizing bacteria, and microbial community structures in groundwater, surface water, and soil from a gold mining area. The analysis revealed that the majority of soil and surface water microbiomes were Proteobacteria, Actinobacteria, Bacteroidetes, and Chloroflexi, while the groundwater microbiomes were dominated exclusively by Betaproteobacteria and Alphaproteobacteria. Geochemical factors influencing microbial structure differed between groundwater and surface water.

Summary: The study aims to develop a bacterial consortium that can biodegrade high molecular weight semi-crystalline polylactic acid (PLA) films at ambient temperature. PLA-degrading bacteria were enriched from polymeric wastes, and four isolated bacteria were mixed as a consortium. The results showed that the consortium successfully degraded PLA films, and the degradation performance was significantly better than that of individual strains.

Summary: The bioconversion of lignocellulosic wastes to value-added biosurfactants was investigated using a single flask to carry out both substrate pretreatment and biosurfactant production. Different lignocellulosic wastes were tested, and corn husk, coconut oil cake, and defatted rice bran were found to provide the highest biosurfactant concentrations. The produced biosurfactants were identified as a mixture of zwitterionic lipopeptides and phospholipids. The biosurfactants exhibited excellent surface tension reduction at a wide range of pH values, salinities, and temperatures. Additionally, they showed lower phytotoxicity compared to a commercial surfactant. This study provides a convenient method for manufacturing biosurfactants from lignocellulosic wastes.
