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 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...
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 کاملThe protective effect of chitin and chitosan against Vibrio alginolyticus in white shrimp Litopenaeus vannamei.
White shrimp, Litopenaeus vannamei, which had been injected with chitin at 4, 6 and 8 microg g(-1) or chitosan at 2, 4 and 6 microg g(-1), were challenged with pathogen Vibrio alginolyticus at 2 x 10(6) colony-forming units (cfu) shrimp(-1) and then placed in seawater of 34 per thousand. The survival of shrimp that received chitin or chitosan at either dose was significantly higher than that of...
