Phylogenetic resolution and habitat specificity of members of the Photobacterium phosphoreum species group.
Substantial ambiguity exists regarding the phylogenetic status of facultatively psychrophilic luminous bacteria identified as Photobacterium phosphoreum, a species thought to be widely distributed in the world's oceans and believed to be the specific bioluminescent light-organ symbiont of several deep-sea fishes. Members of the P. phosphoreum species group include luminous and non-luminous stra...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Prediction and QSAR analysis of toxicity to Photobacterium phosphoreum for a group of heterocyclic nitrogen compounds.
Heterocyclic nitrogen compounds are extensively used as intermediates in the manufacture of pesticides and herbicides, while their toxicity has been little reported (Chen et al, 1997). In this paper, we report the toxicity of 14 heterocyclic nitrogen compounds to Photobacterium phosphoreum measured by Microtox® test which has been proposed as a cost-effective prescreening procedure to eliminate...
متن کاملGenetic diversity analysis of isolates belonging to the Photobacterium phosphoreum species group collected from salmon products using AFLP fingerprinting.
An accurate amplified fragment length polymorphism (AFLP) method, including three primer sets for the selective amplification step, was developed to display the phylogenetic position of Photobacterium isolates collected from salmon products. This method was efficient for discriminating the three species Photobacterium phosphoreum, Photobacterium iliopiscarium and Photobacterium kishitanii, unti...
