Nitrogen availability and production of bikaverin and gibberellins in Gibberella fujikuroi
The syntheses of fungal secondary metabolites, such as bikaverin and gibberellins, are not subject to common regulation, but respond to various combinations of signals,such as nitrogen availability, nitrate and the pH of the medium. Expand
Choline and betaine as inducer agents of Pseudomonas aeruginosa phospholipase C activity in high phosphate medium.
It is concluded that although the phosphate control for the synthesis of phospholipase C may exist, it is expressed only under certain favorable culture conditions. Expand
Carnitine resembles choline in the induction of cholinesterase, acid phosphatase, and phospholipase C and in its action as an osmoprotectant in Pseudomonas aeruginosa
It is demonstrated that under conditions of iso or hyperosmolarity, P. aeruginosa utilized carnitine as the carbon, nitrogen or carbon and nitrogen sources and Carnitine acted as an osmoprotectant when the cells were grown in the presence of preferred carbon andnitrogen sources and high NaCl concentrations.

Cholinesterase, acid phosphatase, and phospholipase C ofPseudomonas aeruginosa under hyperosmotic conditions in a high-phosphate medium
The presence of low choline or betaine concentrations in a culture medium containing succinate, NH4Cl, and inorganic phosphate (Pi) as the carbon, nitrogen, and phosphate sources, respectively,Expand
Phospholipids inTrypanosoma cruzi: Phosphoinositide composition and turnover
The polyphosphoinositides from Trypanosoma cruzi were isolated by preparative thin-layer chromatography (TLC) and identified and contained a larger proportion of unsaturated than saturated fatty acids. Expand
Identification, Cloning, and Expression of Pseudomonas aeruginosa Phosphorylcholine Phosphatase Gene
The saturation curve of rPChP-Ec and rP chitin-binding column by phosphorylcholine revealed that these recombinant enzymes, like the purified native PChP, also contained the high- and low-affinity sites for phosphoryLcholine and that the enzyme activity was inhibited by high substrate concentration.

A Pseudomonas aeruginosa PAO1 acetylcholinesterase is encoded by the PA4921 gene and belongs to the SGNH hydrolase family.
The results of this work suggest that the P. aeruginosa ChoE is an AchE that may also be found in Pseudomonas fluorescens, and this ChoE belongs to the SGNH hydrolase family. Expand
Glycine betaine transmethylase mutant of Pseudomonas aeruginosa.
The gene for glycine betaine transmethylase (gbt) was identified in Pseudomonas aeruginosa strain Fildes III by biochemical, physiological, and molecular approaches and displayed similarity to transferases of different microorganisms. Expand
Degradation of tetradecyltrimethylammonium by Pseudomonas putida A ATCC 12633 restricted by accumulation of trimethylamine is alleviated by addition of Al3+ ions
Aims:  To establish if tetradecyltrimethylammonium (TDTMA) might be degraded by pure culture of Pseudomonas strains, and how the presence of a Lewis’ acid in the medium influences itsExpand
Induction of acid phosphatase and cholinesterase activities in Ps. aeruginosa and their in-vitro control by choline, acetylcholine and betaine
SummaryCholine, acetylcholine and betaine used as a sole carbon source, effectuate in Ps. aeruginosa an acid phosphatase activity in addition to a cholinesterase activity. Induction of both enzymeExpand
