Streptavidins Coordinate Biotin Sequestration and Self‐Resistance Within a Biotin‐Pathway Antibiotic Network

open access: yesAdvanced Science, EarlyView.
A conserved genomic region between two streptavidin genes in Streptomyces packages biosynthetic gene clusters for diverse biotin‐pathway antibiotics: acidomycin, stravidin, the new non‐proteinogenic amino acid ANDA, and the new BioA inhibitor α‐methyl‐KAPA.

Scoping review of the effects of cyanobacterial toxins on human and animal health and potential role in mosquito control

open access: yesDiscover Environment
Cyanobacteria and their associated toxins are widespread, particularly in aquatic environments. Periodic comprehensive assessments of the effects of cyanobacteria and cyanotoxin, within the One Health framework is needed.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

open access: yesAnimal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Health-Based Cyanotoxin Guideline Values Allow for Cyanotoxin-Based Monitoring and Efficient Public Health Response to Cyanobacterial Blooms

open access: yesToxins, 2015
Human health risks from cyanobacterial blooms are primarily related to cyanotoxins that some cyanobacteria produce. Not all species of cyanobacteria can produce toxins.

Cyanotoxins: A dermatological problem [PDF]

open access: yesArchive of Oncology, 2011
Cyanobacteria (blue-green algae), that are common inhabitants of water and terrestrial environments throughout the world, produce a broad spectrum of secondary metabolites - biologically active products that could be toxic (cyano­toxins).

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Review [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 1999
Toxic cyanobacteria are common in Portuguese freshwaters and the most common toxins are microcystins. The occurrence of microcystin-LR (MCYST-LR) has been reported since 1990 and a significant number of water reservoirs that are used for drinking water ...

Marine silicon for biomedical sustainability

open access: yesBMEMat, EarlyView.
Schematic illustrating marine silicon for biomedical engineering. Abstract Despite momentous divergence from oceanic origin, human beings and marine organisms exhibit elemental homology through silicon utilization. Notably, silicon serves as a critical constituent in multiple biomedical processes.

UM BREVE ESTUDO SOBRE A INATIVAÇÃO DA TOXINA MICROCISTINA-LR POR IRRADIAÇÃO GAMA E ANÁLISE POR METODOLOGIAS HPLC-SPE ONLINE E ESPECTROMETRIA DE MASSAS [PDF]

open access: yesQuímica Nova
Many of the toxins produced by cyanobacteria have multiple variants, some being more toxic than others. Microcystins are a group of toxins produced by cyanobacteria that have approximately 100 variants with LD50 (lethal dose 50%) values ranging from 25 ...
