Biosensing the Histamine Producing Potential of Bacteria in Tuna

open access: yesFrontiers in Microbiology, 2019
Histamine poisoning is the most common cause of human foodborne illness due to the consumption of fish products. An enzyme-based amperometric biosensor was developed to be used as a screening tool to detect histamine and histamine-producing bacteria (HPB)

Short communication: Survey of Methyl Tertiary Butyl Ether (MTBE) toxicity using bioassay on Daphnia magna [PDF]

open access: yes, 2011
In this study, the toxicity of MTBE on the crustacean Daphnia magna (Cladocera) has been studied. At the beginning, for finding the range of sensitivity of D. magna to MTBE, a test had been conducted at 24h.

Global and Phylogenetic Distribution of Quorum Sensing Signals, Acyl Homoserine Lactones, in the Family of Vibrionaceae [PDF]

open access: yes, 2014
Bacterial quorum sensing (QS) and the corresponding signals, acyl homoserine lactones (AHLs), were first described for a luminescent Vibrio species. Since then, detailed knowledge has been gained on the functional level of QS; however, the abundance of ...

Évaluation de bioprocédés d'assainissement en phase solide/liquide par l'utilisation de biotests écotoxicologiques. [PDF]

open access: yes, 1996
La relation biodécontamination-détoxication sur des matrices relatives aux sols a été évaluée par le biais de biotests écotoxicologiques. En partant de l'hypothèse selon laquelle la biodégradation ou la bioélimination de contaminants s'accompagne d'une
