The Effect of K-Lactate Salt and Liquid Smoke on Bacterial Growth in a Model System     

Aparna Saha  Sveinung Birkeland 《Journal Of Aquatic Food Product Technology》2017,26(2):192-204

The effects of a commercial lactate salt formulation—containing potassium lactate (KL) and potassium acetate (KA)—and liquid smoke (LS) on the growth of selected lactic acid bacteria (LAB; Carnobacterium maltaromaticum, Carnobacterium inhibens, Lactococcus lactis, Lactobacillus curvatus, and Enterococcus faecalis), fish spoilage bacteria (Photobacterium phosphoreum, Pseudomonas putida, and Vibrio vulnificus), and Listeria innocua, were examined in a tryptic soy broth model system at 20ºC based on BioScreen data. The most pronounced inhibition effect on growth of bacteria was seen in the presence of 6% KL + 0.4% KA, used either combined with LS or alone. Only a minor inhibition effect on growth was found in the presence of LS alone. The only exception was Lactobacillus curvatus, which grew quite well in the presence of LS compared to control medium. The growth of Vibrio vulnificus was prevented in 6% KL + 0.4% KA, and significantly inhibited in the presence of 3% KL + 0.2% KA. When V. vulnificus was grown in NaCl, KA, and KL + KA, it was observed that KL + KA had a better inhibition effect than sodium salt within the same concentration range.  相似文献

Implications of conserving an ecosystem modifier: Increasing green turtle (Chelonia mydas) densities substantially alters seagrass meadows     

Aparna Lal  Rohan Arthur  Núria Marbà  Teresa Alcoverro 《Biological conservation》2010,143(11):2730-2738

Ecosystem modifiers have the ability to significantly alter the ecosystem they inhabit sometimes with serious consequences for their own populations. We evaluated the ability of green turtles (Chelonia mydas) to modify seagrass ecosystems by their foraging activity. This study was conducted in a seagrass-dominated lagoon in the Lakshadweep Islands, Indian Ocean, where a stable high-density congregation of green turtles is present. We determined a gradient of turtle density in the lagoon and measured the intensity of turtle herbivory across the gradient. We then measured the impact of increasing grazing on seagrass structural parameters, growth and flowering along this gradient. Our results indicate that turtles substantially change seagrass meadow structure (canopy height, shoot length, width and density), reduce flowering and can potentially even cause changes in the species composition of the meadow. We discuss the implications of these results for seagrass ecosystem function, green turtle movement and human attitudes. When conserving ecosystem modifiers like the green turtle, any management strategy needs to include a detailed knowledge of the roles these species play in the ecosystems they inhabit.  相似文献

Thyroid hormone modulation of ovarian recrudescence of air-breathing catfish Clarias gariepinus     

A. Supriya  K. Raghuveer  I. Swapna  M. K. Rasheeda  T. Kobayashi  Y. Nagahama  Aparna Dutta Gupta  K. C. Majumdar  B. Senthilkumaran 《Fish physiology and biochemistry》2005,31(2-3):267-270

In the present study, thiourea-induced thyroid hormone depletion and thyroxine (T₄) ‘overdose’ were used as a strategy to understand the influence of thyroid hormones on ovarian recrudescence of juvenile (3-months-old), immature (8-months-old) and adult (1-year-old) air-breathing catfish, Clarias gariepinus. Thiourea-induced thyroid hormone depletion in juvenile catfish impaired ovarian development, but no significant effect was observed in immature catfish and during late stage of ovarian recrudescence of mature catfish. T₄ treatment in females undergoing late stages of ovarian recrudescence induced rapid oocyte growth by promoting its early entry into maturational phase as evident from the presence of more number of vitellogenic and post-vitellogenic follicles, decrease in aromatse immunoreactivity and reduced estradiol–17β levels. Hence, thyroid hormones have an important role to play during early stages of ovarian development and vitellogenesis of catfish and also indicating that thyroid has a stage dependent effect on ovary.  相似文献   

Detection of Anti-listeriolysin O and Listeria monocytogenes in Experimentally Infected Buffaloes (Bubalus bubalis)     

Chaudhari SP  Malik SV  Rekha GB  Barbuddhe SB 《Tropical animal health and production》2001,33(4):285-293

The kinetics of antibody production against listeriolysin O (ALLO) and the recovery pattern of Listeria monocytogenes from bacteriological samples were studied following oral infection of buffalo calves with 3×10⁹ cells each of pathogenic L. monocytogenes. Antibodies to LLO appeared by 7–10 days post infection (PI), with a shallow peak between days 16 and 36 PI, when tested by indirect plate-ELISA. The titres of ALLO in all the animals then declined slowly but remained detectable up to day 70 PI. In dot-ELISA, ALLO could be detected by days 5 to 7 PI, and with higher titres than with the plate-ELISA. The pathogen was recovered at low rates as ALLO first appeared but was absent in the faecal, nasal and blood cultures as production of ALLO peaked.  相似文献

Supplementation of Slow‐Release Melatonin Improves Recovery of Ovarian Cyclicity and Conception in Summer Anoestrous Buffaloes (Bubalus bubalis)          下载免费PDF全文

A Kumar  S Mehrotra  G Singh  VP Maurya  K Narayanan  AS Mahla  RK Chaudhari  M Singh  YK Soni  BL Kumawat  SK Dabas  N Srivastava 《Reproduction in domestic animals》2016,51(1):10-17

The role of melatonin as a protective neurohormone against restoring cyclicity in summer anoestrous animals in photoperiod species has gained wider acceptance. This study was designed to uncover the evidence the slow‐release melatonin (MLT) has on initiation of ovarian cyclicity and conception rate (CR) in summer anoestrous buffaloes. Thus, buffaloes diagnosed as summer anoestrous (absence of overt signs of oestrus, concurrent rectal examination and radioimmunoassay for serum progesterone at 10 days interval) were grouped as untreated (Group I, sterilized corn oil, n = 8) and treated (Group II, single subcutaneous injection of MLT @18 mg/50 kg bwt in sterilized corn oil, n = 20). Animals treated and detected in oestrus were artificially inseminated (AI) followed by division into Group III (second dose of MLT on 5th day post‐AI, n = 8) and Group IV (no melatonin administration, n = 10). Blood samples were collected at 4 days interval for estimation of serum MLT, progesterone and oestrogen using radioimmunoassay kit. Mean oestrous induction rate (OIR), oestrous induction interval (OII), interoestrous interval (IOI) and CR were estimated. Compared to control, concentration of melatonin was significantly (p < 0.05) higher in treated group ranging from 14.34 ± 1.72 to 412.31 ± 14.47 pg/ml whereas other two hormones did not show any concentration difference. Melatonin‐administered buffaloes showed significantly (p < 0.05) higher (90%) OIR with OII of 18.06 ± 1.57 days. Results showed improvement in conception rate in buffaloes administered with post‐insemination melatonin. It can be concluded from the study that slow‐release melatonin supplementation restored cyclicity in summer anoestrous animals resulting in improvement in conception rate in buffaloes.  相似文献
