1. EDTA in borate buffer has a marked bactericidal effect on Pseudomonas alcaligenes, which is more sensitive than Pseudomonas aeruginosa. The bactericidal effect is accompanied by solubilization of lipopolysaccharide and release of intracellular solutes. These effects are more pronounced at pH9.2 than 7.1. 2. Cell walls of P. alcaligenes were prepared and from them were obtained the readily ex...

Preliminary observations in a large-scale fermentation process suggested that the lipase expression of Pseudomonas alcaligenes can be switched on by the addition of certain medium components, such as soybean oil. In an attempt to elucidate the mechanism of induction of lipase expression, we have set up a search method for genes controlling lipase expression by use of a cosmid library containing...

PURPOSE To report a case of epidemic keratoconjunctivitis complicated by Alcaligenes xylosoxidans. METHODS A 37-year-old man suffered epidemic keratoconjunctivitis in both eyes. Eleven days later, he developed a corneal ulcer in his left eye. Bacterial staining, culture, and antibiotics sensitivity test were performed from a corneal scrape. RESULTS The cultures revealed a growth of Alcalige...

The distribution of Tn5271-related DNA sequences in samples of groundwater and a groundwater bioremediation system at the Hyde Park (Niagara Falls, N.Y.) chemical landfill site was investigated. PCR amplification of target sequences within the cha genes of Tn5271 revealed similar sequences in the groundwater community and in samples from the sequencing batch reactors treating that groundwater. ...

The aim of this research was to determine the impact soaking bitter melon seeds in a Pseudomonas alcaligenes and Bacillus sp bacteria suspension on growth yield melon. A randomized block design used with 11 treatments consisting three isolates P. alcaligenes, four sp, one mixed control, each which repeated times for total 44 experimental pots. Data were analyzed using variance test one-way ANOV...

PURPOSE To quantify and compare the in vitro adherence of Staphylococcus epidermidis and Pseudomonas alcaligenes to different intraocular lenses (IOLs). METHODS Fourteen intraocular lenses were used in the experiment. Four of polymethylmethacrylate (PMMA), four of silicone, four of hydrogel and two of acrylic. Eight intraocular lenses were placed in eight test tubes containing 4 ml of Pseudom...

The effects of microorganisms inoculated in beef, pork and chicken on the production of various biogenic amines (BA) were examined. Acinetobacter haemolyticus, Aeromonas hydrophila subsp. hydrophila, Alcaligenes faecalis subsp. faecalis, Bacillus cereus, Bacillus subtilis, Enterobacter aerogenes, Enterobacter cloacae, Escherichia coli, Lactobacillus alimentarius, Lactobacillus curvatus, Leucono...

Alcaligenes faecalis kw-A selected for possessing good denitrification efficiency was used for biofilm development. The biofilm could be developed on a glass surface within 12 hr when 5%, Ix 10(8) cells/ml was used as inoculum. The microcolonies were seen in 6 hr and glycocalyx in 9 hr stage. At 24 hr the biofilm was developed fully and hence was visualised as dense mass. The biofilm protein co...

The objective of this study is to determine the rate of recovery of Alcaligenes faecalis from clinical specimens of blood, cerebrospinal fluid and wound swabs and the antibiogram in a tertiary healthcare institution. The design was prospective and cross-sectional. The subjects for the study were patients seen at the various facilities in the hospital. There were two thousand and eight hundred p...
