A bacterium that was capable of metabolizing atrazine at very high concentrations (>1,000 ppm) was isolated from a herbicide spill site. The organism was differentiated by observing clearing zones on indicator agar plates containing 1,000 ppm atrazine. Detailed taxonomic studies identified the organism as a Pseudomonas sp., designated ADP, that was dissimilar to currently known species. Pseudom...

Las plantas purificadoras de agua que carecen un adecuado sistema control calidad pueden generar problemas salud pública. El objetivo este estudio fue examinar la microbiológica del proveniente pequeñas ciudad Puebla, así como, determinar existencia bacterias Aeromonas sp y Pseudomonas sp, caracterizar si presentan fenotipo patógeno oportunista. Se recolectaron 70 muestras garrafones 25 estable...

This study examines the isolation and characterization of phenol-degrading-bacteria, Five isolates named C2, P4, M4, O3, S3, from effluent ceramic factories (C2), petrochemical (P4), pulp paper mill (M4), crude oil (O3) sewage water (S3) have been investigated. These were characterized depending on their morphological, biochemical characteristics, only one isolate was as a Gram-positive, strict...

In an effort to discover an alternative antibiotic for treating infections with methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas sp. UJ-6, a marine bacterium that exhibited antibacterial activity against MRSA, was isolated. The culture broth and its ethyl acetate extract exhibited bactericidal activity against MRSA. The extract also exhibited antibacterial activity against gram-n...

Alpha-galactosidase is a glycoside hydrolase enzyme that hydrolyses the terminal alpha-galactosyl moieties from glycolipids and glycoproteins. Pseudomonas sp. MCCMB3 an alpha galactosidase producer was isolated from the rock soil of Kulasekaram, Kanyakumari district, South India. Totally 10 strains were isolated, when compared with other strains, predominant enzyme activity has been observed in...

Abstract Endophytic bacteria have been reported to roles as biocontrol agents and plant growth promoters. The application of endophytic in the form mixed culture [consortia] will provide better effectiveness than when applied alone. This study aimed obtain a consortium that is effective biological control for purple blotch [ Alternariaporri ], promote yield shallots. research was arranged compl...

The number and types of microorganisms in the gut of Culex quinquefasciatus larvae varied considerably from one site of collection to another. Larval gut, in general, contained enormous number of bacteria, a few fungi and negligible number of actinomycetes which belonged to 15 bacterial, 6 fungal and 4 actinomycete genera, respectively. Bacillus sp., Staphylococcus sp. and Pseudomonas sp. among...

A strain GP32 which produces a highly viscous extracellular polysaccharide was conducted with soil samples and identified as Pseudomonas species. The culture flask conditions for the production of extracellular polysaccharide by Pseudomonas sp. GP32 were investigated. The most suitable carbon and nitrogen source for extracellular polysaccharide production were galactose and (NH4)2SO4. The optim...

Pseudomonas sp. strain ADP utilizes the human-made s-triazine herbicide atrazine as the sole nitrogen source. The results reported here demonstrate that atrazine and the atrazine degradation intermediates N-isopropylammelide and cyanuric acid are chemoattractants for strain ADP. In addition, the nonmetabolized s-triazine ametryn was also an attractant. The chemotactic response to these s-triazi...
