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. Simultaneously, soil temperature, pH, a

The siderophore, pseudobactin, was isolated from the plant growth promoting rhizobacterium Pseudomonas B10, and its absorption and corrected fluorescence spectra were determined over a range of pH values. These spectra were similar to those reported for other fluorescent siderophores from other Pseudomonas, so that differentiation of pseudobactin from such related siderophores by absorption or fluorescence spectra is not feasible.

Introduction. DFUs are challenging chronic wounds that are vulnerable to infections. A fluorescence imaging device was developed to detect bacterial presence in wounds. This device utilizes the principle that when illuminated by violet light, some bacteria emit red fluorescence and others, such as Pseudomonas aeruginosa, emit cyan fluorescence. Several studies have reported the accuracy of this device. However, to the best of the authors’ knowledge, no studies have examined the correlation between bacterial presence and tissue biopsy culture results in diabetic wounds. Objective. This study ai

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).

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 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. A novel technique for the study of MIC in soil to further the understanding of localized corrosion on the external surface of water pipelines is being developed. 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 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

Iron is the fourth most abundant element in the soil, but since it forms insoluble hydroxides at neutral and basic pH, it often falls short of meeting the basic requirements of plants and microorganisms. Most aerobic and facultative aerobic microorganisms possess a high-affinity Fe transport system in which siderophores are excreted and the consequent Fe complex is taken up via a cognate specific receptor and a transport pathway. The role of the siderophore in Fe uptake by plants and microorganisms was the focus of this study. In this research Rhizopus arrhizus was found to produce a novel sid

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
