Soil microbial communities and degradation of pesticides in greenhouse effluent through a woodchip bioreactor.

Pesticides, including insecticides and fungicides, are major contaminants in the effluent from intensive agricultural systems, such as greenhouses. Because of their constant use and persistence, some pesticides can accumulate in soil and/or run off into adjacent waterways. Microbial communities in soil can degrade some pesticides, and bioreactors with enhanced microbial communities have the potential to facilitate decontamination before the effluent is released into the environment.

Semi-purified Antimicrobial Proteins from Oyster Hemolymph Inhibit Pneumococcal Infection.

Pneumococcal infections caused by Streptococcus pneumoniae are a leading cause of morbidity and mortality globally, particularly among children. The ability of S. pneumoniae to form enduring biofilms makes treatment inherently difficult, and options are further limited by emerging antibiotic resistance.

Pesticide occurrence in a subtropical estuary, Australia: Complementary sampling methods.

Monitoring pesticide run-off in the aquatic environment is ecologically important. Effective methods are required to detect the wide range of possible pesticides that enter estuaries from the surrounding catchment. Here, we investigate the occurrence of pesticides in the Richmond River estuary, Australia, and compare the effectiveness of using oysters and Chemcatcher® passive sampling devices against composite water samples.

Toward non-invasive collection methods for sampling the microbiome of diabetic foot ulcers.

Identifying the microbiome within chronic diabetic foot ulcers is essential if effective antimicrobial therapies are to be administered. Using culture and 16S rRNA gene sequencing, the aim of this study was to compare the microbiome of paired tissue scraping samples with swab samples, collected from participants during attendance at a high-risk foot clinic. The mean richness of cultured swab and tissue scraping samples was consistent, with anaerobes infrequently isolated from both sample types.
