Microbiota from Litopenaeus vannamei: digestive tract microbial community of Pacific white shrimp (Litopenaeus vannamei)
Bacteria capable of producing different extracellular enzymes of potential relevance in digestive processes were isolated from the stomach, hepatopancreas and intestine of Pacific white shrimp Litopenaeus vannamei. A total of 64 strains with proteolytic activity were isolated and grouped into 16 clusters based on morphological characteristics: 4 groups were isolated from the intestine; 5 from t...
متن کاملCuticular chitin synthase and chitinase mRNA of whiteleg shrimp Litopenaeus vannamei during the molting cycle
Cuticular chitin synthase and chitinase mRNA of whiteleg shrimp Litopenaeus vannamei during the molting cycle a b s t r a c t a r t i c l e i n f o Chitin metabolism is of high relevance for shrimp growth because it has to be synthesized and cleaved in each molt. We studied chitin synthase and chitinase mRNAs from whiteleg shrimp Litopenaeus vannamei. For this, cDNA coding for cuticular chitin ...
متن کاملSNPs of hemocyanin C-terminal fragment in shrimp Litopenaeus vannamei.
In this study, we identified a variable region in the C-terminus of hemocyanin from the shrimp Litopenaeus vannamei (2288-2503bp, HcSC) by sequence alignments. A total of 13 SNPs were identified by PCR-SSCP and HcSC clone sequencing. The SSCP patterns of HcSC could be modulated in Vibro parahaemolyticus-treated shrimps. A novel SSCP band with four SNP sites was identified in V. parahaemolyticus...
متن کاملNoradrenaline modulates the immunity of white shrimp Litopenaeus vannamei.
The total haemocyte count (THC), phenoloxidase activity, respiratory burst, superoxide dismutase (SOD) activity, phagocytic activity and clearance efficiency in response to pathogen Vibrio alginolyticus were measured when the white shrimp Litopenaeus vannamei (18.4 +/- 1.2 g) were injected individually with noradrenaline at 10(-8), 10(-7) and 10(-6) mol shrimp(-1). For the shrimp that received ...
متن کاملEnzyme assisted extraction of chitin from shrimp shells (Litopenaeus vannamei)
8 BACKGROUND: Chemical chitin extraction generates large amounts of wastes and increases partial 9 deacetylation of the product. Therefore, the use of biological methods for chitin extraction is an 10 interesting alternative. The effects of process conditions on enzyme assisted extraction of chitin from 11 the shrimp shells in a systematic way were the focal points of this study. 12 RESULTS: De...
