The novel, cream colored, Gram-staining-negative, rod-shaped, motile bacteria, designated strains AK15(T) and AK18, were isolated from sediment samples collected from Palk Bay, India. Both strains were positive for arginine dihydrolase, lysine decarboxylase, oxidase, nitrate reduction and methyl red test. The major fatty acids were C16:0, C18:1 ω7c, C16:1 ω7c and/or C16:1 ω6c and/or iso-C15:0 2...
Photobacterium profundum is a cosmopolitan marine bacterium capable of growth at low temperature and high hydrostatic pressure. Multiple strains of P. profundum have been isolated from different depths of the ocean and display remarkable differences in their physiological responses to pressure. The genome sequence of the deep-sea piezopsychrophilic strain Photobacterium profundum SS9 has provid...
Gilthead sea bream (Sparus aurata) is a species of paramount importance to the Mediterranean aquaculture industry, with an annual production exceeding 140,000 metric tonnes. Pasteurellosis due to the Gram-negative bacterium Photobacterium damselae subsp. piscicida (Phdp) causes significant mortality, especially during larval and juvenile stages, and poses a serious threat to bream production. S...
In the large-quantity production of α2,3- and α2,6-sialyllactose (Neu5Ac(α2,3)Galβ1,4Glc (3'-SL) and Neu5Ac(α2,6)Galβ1,4Glc (6'-SL)) using sialyltransferases (STs), there are major hurdles to overcome for further improvement in yield and productivity of the enzyme reactions. Specifically, Pasteurella multocida α2,3-sialyltransferase (α2,3PST) forms a by-product to a certain extent, owing to its...
Three different immunoglobulin (Ig) isotypes can be found in teleost fish, IgM, IgD, and the teleost-specific IgT. IgM is considered to have a systemic activity, and IgT is attributed a mucosal role, similar to mammalian IgA. In this study, the complete sequence of gilthead sea bream IgM and IgT in their membrane (m) and soluble (s) forms are described for the first time in a perciform fish. Th...
چکیده زمینه و هدف: امروزه افزایش استفاده بی رویه از آنتی بیوتیک ها سبب ایجاد فرم مقاوم باکتری ها شده است. لذا یافتن ترکیبات ضد میکروبی فعال زیستی مورد توجه محققان است. هدف از این مطالعه بررسی آزمایشگاهی اثر ضد میکروبی عصاره اتیل استاتی جلبک دریایی قرمز (gelidiella acerosa) بر برخی باکتری های گرم مثبت و گرم منفی می باشد. مواد و روش ها: در این مطالعه آزمایشگاهی، پس از نمونه برداری، عصاره اتیل است...
