“…Higher WHC value was found in NSLDPE packed shrimps, which might be associated with the lesser degradation of muscle proteins of control shrimp. Since the production of bacterial enzymes combined with the endogenous enzymes leads to the acceleration of protein decomposition [2], NSLDPE packaging might delay the WHC decline of Pacific shrimp by inhibiting the microbial growth in some respects.…”

“…Whiteness was used to evaluate the degree of discoloration [26]. The inhibitory effect of NSLDPE packaging on WI decrease was in according with the effect of MAP, conducted by Qian et al [2], which might be associated with slower melanosis. The increase of the WI in the first 2 days could be ascribed to the denaturation of protein, which led to opaque flesh and whiteness, according to Lopez et al [27].…”

“…In China, S. marisflavi caused high mortality in sea cucumbers (Li et al , ), and S. aquimarina was associated with a lesion syndrome of sea urchin (Wang et al , ). In shrimp, Shewanella species, and especially S. putrefaciens and S. baltica , were associated with spoilage of P. vannamei stored at low temperature (Qian et al , ; Qian et al , ; Zhu et al , ), and Shewanella species were also found to be a normal part of the bacterial flora in the P. vannamei gut (Suo et al , ).…”

Summary Early mortality syndrome (EMS) in cultivated shrimp is of complex aetiology. One of the causes is acute hepatopancreatic necrosis disease (AHPND) caused by unique Vibrio isolates that carry two Pirvp toxin genes, but other causes of EMS remain mostly unexplained. Here, we describe the discovery of a Shewanella isolate TH2012T from an EMS/AHPND outbreak pond and demonstrate its virulence for shrimp (the mean lethal concentration of 105 colony‐forming units per millilitre by immersion challenge) accompanied by distinctive histopathology, particularly of the ventral nerve cord and lymphoid organ but also including the digestive tract. On the basis of its complete genome sequence, multilocus phylogenetic trees, digital DNA–DNA hybridization analysis and differential phenotypic characteristics, we propose that Shewanella isolate TH2012T represents a novel species, separated sufficiently from the type strains S. litorisediminis and S. amazonensis to justify naming it Shewanella khirikhana sp. nov. Analysis of the TH2012T genome revealed no homologues of the Pirvp toxin genes but revealed a number of other potential virulence factors. It constitutes the first Shewanella isolate reported to be pathogenic to shrimp.

“…Pacific white shrimp (Litopenaeus vannamei) is one of the most important seafood traded worldwide as well as considerably representative aquatic products for its positive culinary quality and high nutritional values (Oosterveer 2006;Qian et al 2013). However, fresh shrimp has a short shelf life, which causes substantial practical problems for its transportation and distribution, and the nutritional compositions of shrimp may be destroyed by various factors, i.e.…”

Optimization of thermophysical properties of Pacific white shrimp (Litopenaeus vannamei) previously treated with freezing-point regulators using response surface methodology

Three freezing-point regulators (glycine, sodium chloride and D-sorbitol) were employed to optimize thermophysical properties of Pacific white shrimp (Litopenaeus vannamei) using response surface methodology (RSM). The independent variables were glycine content (0.250-1.250 %), sodium chloride content (0.500-2.500 %) and D-sorbitol content (0.125-0.625 %) and analysis of variance showed that the effects of glycine, sodium chloride and D-sorbitol on the thermophysical properties were statistically significant (P < 0.05). The coefficient of determination, R (2) values for initial freezing point (T i ), unfreezable water mass fraction (W u ), apparent specific heat (C app ) and Enthalpy (H) were 0.896 ~ 0.999. The combined effects of these independent variables on T i , W u , C app and H were investigated. The results indicated that T i , C app and H varied curvilinearly with increasing of glycine, sodium chloride and D-sorbitol content whereas W u increased nearly linearly. Based on response plots and desirability functions, the optimum combination of process variables for Pacific white shrimp previously treated with freezing-point regulators were 0.876 % for glycine content, 2.298 % for sodium chloride content and 0.589 % for D-sorbitol content, correspondently the optimized thermophysical properties were T i , - 5.086 °C; W u , 17.222 %; C app , 41.038 J/g °C and H, 155.942 J/g, respectively. Briefly, the application of freezing-point regulators depressed T i and obtained the optimum W u , C app and H, which would be obviously beneficial for the exploitation of various thermal processing and food storage.
