Development of pure culture biofilms of P. putida on solid supports
(Wiley Subscription Services, Inc., A Wiley Company, 1991-03-15)
Pseudomonas putida biofilms were developed on and biofilm accumulation rate data were obtained for the following two classes of support materials: charged surfaces and noncharged hydrophobic and hydrophilic surfaces. The ...
Etiologic role of lactic dehydrogenase virus infection in an age-dependent neuroparalytic disease in C58 mice
(Elsevier, 1980-05)
Lactic dehydrogenase virus (LDV) associated with transplantable line Ib lymphocytic leukemia in C58/Wm mice, K36 lymphocytic leukemia in AKR/J mice, and the Gardner lymphosarcoma in C3H/HeJ mice elicited a fatal neuroparalytic ...
Identification of a conditionally essential heat shock protein in Escherichia coli
(Elsevier, 1994-08-17)
Protein D48.5 was recognized as a heat-inducible protein of Escherichia coli during the screening of a group of random, temperature-inducible Mud-Lac fusion mutants. Physiological and genetic analysis demonstrated that (i) ...
Heterologous expression of tylosin polyketide synthase and production of a hybrid bioactive macrolide in Streptomyces venezuelae
(Springer-Verlag, 2006-02-22)
Tylosin polyketide synthase (Tyl PKS) was heterologously expressed in an engineered strain of Streptomyces venezuelae bearing a deletion of pikromycin PKS gene cluster using two compatible low-copy plasmids, each under the ...
Analytical solutions to a generalized growth equation
(Elsevier, 1984-10-30)
Systems of the form occur in the analysis of biological networks. They also include as special cases the known growth laws and probability functions, famous differential equations like those of Bessel, Chebyshev, and ...
Effects of rifampicin, streptolydigin and actinomycin D on the replication of Col E1 plasmid DNA in Escherichia coli
(Elsevier, 1973-04-15)
We recently reported (Clewell et al., 1972) on an inhibitory effect of rifampicin on Col E1 plasmid replication. The present study represents a further characterization of this phenomenon as well as a study of the effects ...
Growth equations: A general equation and a survey of special cases
(Elsevier, 1980-04)
Although growth in its various manifestations has been studied for centuries and although there are a large number of well-established growth "laws," that work is almost entirely empirical and lacks a theoretical foundation ...
Amino acid sequence of pheromone-inducible surface protein in Enterococcus faecalis, that is encoded on the conjugative plasmid pPD1
(Elsevier, 1990-07-02)
The major pheromone-inducible protein, PD78, believed to contribute to bacterial conjugation, was purified from Enterococcus (formerly Streptococcus) faecalis cells containing the plasmid pPD1. A cloned EcoRI-Bg/II 3.6-kbp ...
Co-ordinate expression of virulence genes by ToxR in Vibrio cholerae
(Blackwell Publishing Ltd, 1992-02)
Evolution of complex regulatory pathways that control virulence factor expression in pathogenic bacteria indicates the importance to these organisms of being able to distinguish time and place. In the human intestinal ...
[lambda] N antitermination system: Functional analysis of phage interactions with the host NusA protein
(Elsevier, 1987-04-20)
Coliphage [lambda] gene expression is regulated temporally by systems of termination and antitermination of transcription. The [lambda]-encoded N protein (pN) acting with host factors (Nus) at sites (nut) located downstream ...
