The present study was aimed at the evaluation of soil temperature, pH and carbon dioxide evolution on the number and efficiency of fluorescent pseudomonads around the root system of Pokkali rice at Vytilla in Ernakulam district of Kerala. Two plots (40 m2) comprising control (without application of Pseudomonas fluorescens) and P. fluorescens treated plants were used for the field experiment. The isolates of fluorescent Pseudomonads or Pseudomonas fluorescence were counted and their efficiency was assessed for IAA, ammonia, HCN and siderophore production.

Tryptose broth (TB) was inoculated with Listeria monocytogenes (strain Scott A or California), Pseudomonas aeruginosa, Pseudomonas flourescens, or a combination of L. monocytogenes plus Pseudomonas species, and incubated at 7 or 13°C for 8 weeks. McBride Listeria Agar was used to determine numbers of L. monocytogenes and Pseudomonas Isolation Agar to enumerate Pseudomonas species at 0, 7, 14, 28, 42, or 56 d. At 13°C, presence of P. fluorescens had a slight negative effect on growth of L. monocytogenes strain Scott A, and was somewhat detrimental to its survival during the extended incubation.

Cyanide-degrading activity was localized to cytosolic cell fractions and was observed at substrate concentrations as high as 100 mM. Two cyanide degrading activities were identified by: (i) the determination of reaction products stoichiometries, (ii) requirements for NADH and oxygen, and (iii) kinetic analysis. The first activity produced CO2 and NH3 as reaction products, was dependent on oxygen and NADH for activity, and displaye

Thus, prevention of bacterial adhesion processes on metal surfaces would be one of the potential weapons to avoid MIC. Serum globulin and by-products were used to prevent bacterial adhesion on different corrosion resistant metal surfaces generally used as implantable biomaterials.

Abstract Seventy percent of the Australian water pipeline network, predominately critical transmissions mains, is constructed of ferrous materials which are highly susceptible to corrosion, particularly microbiologically influenced corrosion (MIC), when buried in soil.

This novel test method utilizes agar to simulate both the physical structure and chemical components of soil more closely than the traditionally used aqueous solutions.

Abstract Preliminary work devoted to elucidate the action of glutaraldehyde (GA) on Pseudomonas fluorescens and Desulfovibrio desulfuricans biofilms formed on AISI 304L SS and SAE 1020 mild steel is presented. Results show that efficacy of GA on planktonic cells is markedly higher than that on sessile cells. GA efficacy on biofilms formed on AISI 304L SS coupons (which are copious and cover large areas) is lower than that observed for SAE 1020 mild steel (which present a patchy distribution and scarce mucilaginous masses). It is concluded that biocidal activity of GA depends markedly on the na

Abstract The effect of dissolved ozone on heat exchanger structural materials (carbon steel, stainless steel, copper and 70:30 copper nickel) has been studied in laboratory experiments, within the concentration range of 0.1 - 1.0 ppm. The biocidal efficacy of ozone on planktonic and sessile growth of Pseudomonas fluorescens was studied in quiescent and flow conditions. Ozone was able to kill the total number of planktonic bacteria in synthetic cooling water. However, ozone is only capable of inducing a partial reduction of bacterial numbers in the case of sessile bacteria. The electrochemical

Abstract Organic film-forming inhibitors used in oil and gas production and transport operations could be susceptible to microbial degradation during their use with the consequent loss in efficiency in corrosion inhibition. The performance of one such organic film-forming corrosion formulation to inhibit corrosion of carbon steel was assessed in a simple mineral medium containing 15.0 ppm sodium chloride. The fluid was inoculated with a Pseudomonas fluorescens pure culture or with a mixed culture of sulfate-reducing bacteria. The inhibitor mixture was the sole carbon source in the system. Micr

Abstract Laboratory experiments under well defined conditions (water chemistry, microbial strains, substrata composition, and experimental techniques) were made to assess the biocidal action of ozone on pure and mixed bacterial biofilms. Bacterial biofilms of Pseudomonas fluorescens, or anaerobic biofilms of two different strains of sulphate-reducing bacteria, were exposed to ozone concentrations within the range of 0.2 to 1 ppm under quiescent conditions. Biofilms were formed on SAE 1020 carbon steel and on AISI type 304L stainless steel samples. The effect of ozone on the corrosion behavior

The main objective of this study was to develop data that would facilitate a consistently effective method of biological control of fire blight disease to be developed and to enable its implementation for disease control by ensuring its compatibility with variations in the biological, environmental, and chemical conditions present in pear orchards. As considerable information on the pathogen and biological control of fire blight was already gathered from studies in California and elsewhere, an emphasis was placed on investigating the genetics and ecology of Erwinia amylovora, the causal agent

This research was aimed to develop an active film from chitosan film incorporated with green tea extract to enhance antioxidant and antimicrobial properties in order to be used for food shelf life extension. The experiments were divided into 3 parts. Firstly, chitosan-based film preparation and modification were determined. The results suggested that the optimum chitosan films could be prepared from 2% chitosan in 1% acetic acid. However, the chitosan film was brittle and had low flexibility. Mechanical property of chitosan film was modified by adding different concentrations of glycerol, as a
