Screening of Alginate Lyase-Producing Bacteria and Optimization of Media Compositions for Extracellular Alginate Lyase Production
Background: Alginate is a linear polysaccharide consisting of guluronate (polyG) and mannuronate (polyM) subunits. Methods: In the initial screening of alginate-degrading bacteria from soil, 10 isolates were able to grow on minimal medium containing alginate. The optimization of cell growth and alginate lyase (algL) production was carried out by the addition of 0.8% alginate and 0.2-0.3 M NaCl ...
متن کاملStenotrophomonas maltophilia in Salad
To the Editor: Stenotrophomonas maltophilia has emerged as an important nosocomial pathogen, especially in debilitated and immunocompro-mised persons (1). However, comparatively little is known of the epidemiology of this bacterium, and sources and routes of transmission of S. mal-tophilia are not well understood. The bacterium is widely distributed in the environment, including in plant rhi-zo...
متن کاملStenotrophomonas maltophilia keratitis and scleritis.
BACKGROUND Stenotrophomonas maltophilia is a seldom-reported pathogen in ocular infections. The report describes six cases of Stenotrophomonas maltophilia (S. maltophilia) keratitis and scleritis. To our knowledge, this is the foremost report of S. maltophilia scleritis. METHODS Laboratory reports of patients diagnosed with S. maltophilia ocular infections were collected from the ophthalmic d...
متن کاملReassessment of Stenotrophomonas maltophilia phenotype.
Standard microbiology references describe Stenotrophomonas maltophilia as oxidase negative and variable with respect to utilization of lactose and sucrose. Analysis of a collection of 766 S. maltophilia isolates indicated that approximately 20% are oxidase positive and that this species should be reevaluated for other phenotypes, including oxidative fermentation of lactose and sucrose.
متن کاملA specific polymerase chain reaction method to identify Stenotrophomonas maltophilia.
Stenotrophomonas maltophilia is a multidrug-resistant nosocomial pathogen that is difficult to identify unequivocally using current methods. Accordingly, because the presence of this microorganism in a patient may directly determine the antimicrobial treatment, conventional polymerase chain reaction (PCR) and real-time PCR assays targeting 23S rRNA were developed for the specific identification...
