Conventional oil spill recovery practices can damage sensitive habitats, like freshwater shorelines, and leave residual in the environment, causing chronic exposure to interacting biota. Non-invasive remediation efforts are required enhance of after primary without further environmental damage. Engineered Floating Wetlands (EFWs), also known as Treatment Wetlands, have been used around world for phytoremediation biodegradation aquatic contaminants. EFWs potential increase crude by enhancing surface area microbial colonization interaction with contaminants water column. To assess changes prokaryotic eukaryotic communities associated conjunction shoreline washing, a contained diluted bitumen was conducted enclosure an experimental lake at International Institute Sustainable Development Experimental Lakes Area, northwestern Ontario, Canada, 2019. Total polycyclic aromatic compound (PAC) concentrations column peaked 20 days post spill, declining near background conditions day 66, were dominated 2-, 3-, 4-ring alkylated PACs. Although total sediment PACs highly variable influenced pyrogenic sources (e.g., retene from wood combustion/forest fires) all sites, indicated influence bitumen. The EFW community diverse evenly distributed, while had lower richness evenness, few dominant organisms. our knowledge, this first in-lake experiment studying under natural conditions, responding scientific industrial research needs. While we unable confirm whether shifts result or seasonal changes, supported diversity, presence amplicon sequence variants capable degrading need bacterial inoculation. Further should other products commonly transported Canada. As well, assessing target PAC degradation rates, requirements, activity will continue advance collective knowledge field on secondary strategy.

Co-Inoculation of Trichoderma harzianum and Bradyrhizobium Species Augment the Growth of Schizolobium parahyba var. parahyba (Vell.) Blake Seedlings

Microorganisms, Journal Year: 2025, Volume and Issue: 13(3), P. 630 - 630

The adoption of “consortium” potential microorganisms can optimize the forest seedling production process. objective this study was to evaluate in greenhouse conditions effect co-inoculation between Trichoderma harzianum, Bradyrhizobium diazoefficiens, and B. elkanni on growth Schizolobium parahyba var. (Vell.) Blake seedlings. treatments consisted fungi strains (T. harzianum ESALQ 1306); bacteria (B. (SEMIA 5080) + diazoefficiens 587)); consortium (Trichoderma +Bradyrhizobium), a control treatment. seeds were sown, evaluations carried out 120 days after sowing. variables analyzed shoot height (SH), stem diameter (SD), root length (RL), fresh mass (SFM), (RFM), total biomass (TFM), dry (SDM), (BIO), Dickson quality index (DQI). evaluated proved be effective S. parahyba, with emphasis for parameters, promoting an increase SH (23%), SD (36%), RL (84%). For mass, non-inoculated seedlings (control) obtained decrease 67% (TFM) 83% (BIO) compared co-inoculation. results indicate promising method production; biostimulators allowed plant development, which led success morphometric indices. mechanisms involved microorganisms’ native wood species allow their large scale silvicultural sector are still scarce, new research is needed elucidate physiological biochemical involved.

Bacterial dynamics and exchange in plant-insect interactions

Current Research in Insect Science, Journal Year: 2025, Volume and Issue: unknown, P. 100110 - 100110

In nature, plants and insects engage in intricate interactions. Despite the increasing knowledge of microbiomes insects, extent to which they exchange alter each other's remains unclear. this work, bacterial community associated with nymphs Philaenus spumarius (Hemiptera: Aphrophoridae), stems Coleostephus myconis where were feeding, foam produced by nymphs, studied culture-dependent -independent approaches, an attempt elucidate bacteria between insects. The results suggest that both approaches complement other, as many genera identified metabarcoding not detected culturing, vice versa. Overall, exhibited higher diversity than all samples showing enrichment known provide diverse benefits their host. Stems most similar composition, but Burkholderiaceae Moraxellaceae dominated stems, whereas Rhizobiaceae Sphingobacteriaceae foam. Nymphs exhibit distinct yet more found stem compared Indeed, enriched on endosymbiotic bacteria, mostly Candidatus Sulcia Sodalis, Nevertheless, during appeared several C. myconis, a significant number being incorporated into bacteriome nymph. Curvibacter, Cutibacterium, Methylobacterium, Pseudomonas Rhizobium are likely exchanged. also appear foam, notably species from Enhydrobacter, Pseudomonas, Roseomonas genera. More studies infer functions shared P. spumarius-C. needed.
