Comparison of nano-hydroxyapatite productivity by Pseudomonas aeruginosa and Serratia marcescense through encapsulation method

comparison of nano-hydroxyapatite productivity by pseudomonas aeruginosa and serratia marcescense through encapsulation method

objective(s):   the production of nano-hydroxyapatite by two encapsulated bacterial strains was the goal of current research.  materials and methods:   serratia marcscens atcc 14756 and pseudomonas aeruginosa ptcc 1570 were used by two methods including encapsulated form in 2% (w/v) alginate sodium powder and inoculated form (10%) in nutrient broth medium containing alginate sodium blank beads....

Comparison of Biosorption of Cadmium (II) from Aqueous Solution, by Bacillus Sp and Pseudomonas Aeruginosa

Comparison between batch and fed-batch production of rhamnolipid by Pseudomonas aeruginosa

This paper presents a comparison between batch and three different sets of fed batch fermentations forrhamnolipid production by Pseudomonas aeruginosa. The batch run was performed with 500 ml of culturemedium having the initial glycerol and sodium nitrate concentrations of 30 and 8.3 g/l, respectively. For a fedbatch run with nitrogen source in feed, 250 ml of the nitrogen exc...

The effect of bromhexine, gentamicin and imipenem on biofilm of standard bacterial Escherichia coli and Pseudomonas aeruginosa by ELISA method

Background: Biofilms are a collection of microorganisms that have the ability to stick to different levels. Due to the difficulty of treatment of bacterial biofilm infections and their lack of recognition by conventional diagnostic methods, this study aimed to provide a new method of identification and the effect of related drugs on Pseudomonas aeruginosa and Escherichia coli biofilms. Material...

تجزیه زیستی مالاتیون توسط کشت میکس سویه‌های Serratia marcescens BNA1 و Pseudomonas aeruginosa BNA2

Background and Objectives: Organophosphate pesticides are used most commonly for domestic, commercial, and agricultural purposes and have been found to be highly toxic. In essence, bioremediation has become one of the most important tools for removing these compounds in the environment, considering its higher efficiency when compared with the physicochemical methods. Materials and Methods: T...

Phosphate limitation induces the intergeneric inhibition of Pseudomonas aeruginosa by Serratia marcescens isolated from paper machines

Phosphate is an essential nutrient for heterotrophic bacteria, affecting bacterioplankton in aquatic ecosystems and bacteria in biofilms. However, the influence of phosphate limitation on bacterial competition and biofilm development in multispecies populations has received limited attention in existing studies. To address this issue, we isolated 13 adhesive bacteria from paper machine aggregat...
