Screening Relaxants for Efficacy and Effects on Growth for Greenlip Abalone, Haliotis laevigata Donovan

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.
ABSTRACT Relaxants are used in abalone aquaculture to facilitate handling, transport and grading stock, with minimal injury, stress, immune suppression and mortality. Benzocaine has been commonly used as an abalone relaxant but negative behavioural responses to exposure have been observed, and in some countries it has a withholding period, precluding ...

Expression and characterization of a 9-cis-epoxycarotenoid dioxygenase from Serratia sp. ATCC 39006 capable of biotransforming isoeugenol and 4-vinylguaiacol to vanillin

open access: yesBiotechnology Reports, 2018
A 9-cis-epoxycarotenoid dioxygenase gene from Serratia sp. ATCC 39,006 (SeNCED) was overexpressed in soluble form in E.coli. SeNCED showed the maximum activity at 30 °C and pH 8.0, and it was stable relatively at range of pH 5–10 and temperature of 20 °C
