Investigation of bacteria composition in Artemia biomass culture under different conditions
نویسندگان
چکیده
This study was conducted to determine the bacterial composition and its effect on Artemia performance in various biomass culture conditions. Newly hatched franciscana were cultured 1.5L plastic bottles containing 1L of medium, with a density 200 nauplii/L salinity 30 ppt, lasted for three weeks. In first two days after stocking, fed Chaetoceros sp. Afterward, Artemia-formulated feed used as daily food. biofloc bacteria treatments, C/N ratio regularly manipulated medium from day 5 onwards. The statistical analysis results showed that conditions, well development those batches, affected performance. best survival rate, individual length, obtained seawater treatment 21 culturing. total varied 83–146 × 103 CFU/mL, highest value seen (BF) treatments. treatments had significantly higher than non-biofloc Nitrosomonas better developed (SW) while Nitrobacter sea salt (SS) medium.

Gas chromatography mass spectrometry (GC-MS) and headspace gas chromatography mass spectrometry (HS/GC-MS) were used to study metabolites produced by Lactococcus lactis subsp. cremoris MG1363 grown at a temperature of 30 °C with and without agitation at 150 rpm, and at 37 °C without agitation. It was observed that L. lactis produced more organic acids under agitation. Primary alcohols, aldehyde...
متن کاملMetabolic Heat Production by Artemia Embryos under Anoxic Conditions
The metabolic status of encysted Artemia embryos under anoxic conditions has been studied by calorimetry. Previous work demonstrated a very low, but still measurable, source of metabolic heat (31nWmg21 drymass) after 6 days of anoxia, attributed to the catabolism of small amounts of carbohydrate storage compounds and the unusual nucleotide diguanosine tetraphosphate. Our results indicate that t...
