1. Desenvolvimento de um método de imobilização-conservação de algas utilizadas em teses ecotoxicológicos
Os testes de toxicidade com algas são importantes para se avaliar o efeito ambientar de substâncias químicas no meio aquático. Os protocolos atuais de execução destes testes exigem uma cultura algal permanente, o que eleva os custos, aumenta a carga laboratorial e acarreta riscos de contaminação ao se fazer, periodicamente, a repicagem da cultura par

2. Effects of No. 2 Fuel Oil, Nigerian Crude Oil, and Used Crankcase Oil on Attached Algal Communities: Acute and Chronic Toxicity of Water-Soluble Constituents
Water extracts of a no. 2 fuel oil, a Nigerian crude oil, and used crankcase oil were examined for their effects on algal communities in experiments lasting several weeks conducted under near-natural conditions. No. 2 fuel oil extracts depressed algal biomass (chlorophyll a) and resulted in blue-green algal (cyanobacterial) dominance and decreased diatom occ

3. Pseudoalteromonas Bacteria Are Capable of Degrading Paralytic Shellfish Toxins▿ †
Marine bacterial isolates cultured from the digestive tracts of blue mussels (Mytilus edulis) contaminated with paralytic shellfish toxins (PSTs) were screened for the ability to reduce the toxicity of a PST mixture. Seven isolates reduced the overall toxicity of the algal extract by ≥90% within 3 days. These isolates shared at least 99% 16S rRNA gene sequ
