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 کاملMolecular Response of Carbohydrate Metabolism to Dietary Carbohydrate and Acute Low Salinity Stress in Pacific White Shrimp Litopenaeus vannamei
Molecular response of carbohydrate metabolism in Litopenaeus vannamei was evaluated at transcriptional level through quantitative real-time PCR analysis. The mRNA expressions of six genes hexose-6-phosphotransferase, pyruvate kinase, phosphoenolpyruvate carboxykinase, crustacean hyperglycemic hormone, glucose transporter and insulin-like growth factors binding protein in the hepatopancreas, mus...
متن کاملMicrobiome analyses of pacific white shrimp (Litopenaeus vannamei) collected from disparate geographical locations.
In this study, the tail muscle microbiota of pacific white shrimp (Litopenaeus vannamei) sourced from five countries across Central and South America and Southeast Asia were determined and compared. The genomic DNA was sequenced at around 10 × coverage for each geographical location and was assembled de novo for comparative analysis. The assembled sequences for all the lines were classified bas...
متن کاملBiochemical properties of polyphenoloxidase from the cephalothorax of Pacific white shrimp (Litopenaeus vannamei)
Melanosis is a major problem associated with the quality loss of Pacific white shrimp. This is mediated by polyphenoloxidase (PPO), in which biochemical and molecular properties can be varied with species, molting period, etc. The better understanding of PPO characteristics should pave a way for lowering melanosis, thereby extending the shelf life of Pacific white shrimp during handling and sto...
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 ...
