Shoot regeneration in safflower (Carthamus tinctorius 'AKS 207' and 'PKV Pink') genetically transformed using Agrobacterium was used for assessing various constraints to the efficiency of transformation including infection period, virulence induction medium, co-cultivation period, bacterial titre, selection regime, and the natural phenolic compound acetosyringone. Transformation frequency was p...

The control and management of fungal diseases is a worldwide problem. A variety microbial pigments have excellent antibacterial effects, naturally occurring bacterial may help in tackling diseases. In order to explore the basic properties biological functions pink pigment produced by Erwinia persicina Cp2, we used organic solvents extract pigment, analyzed physicochemical determined chemical co...

Abstract The Ajuda Songbook is an exceptional illuminated manuscript being the only surviving codex of Galician-Portuguese secular poetry; it was produced in end thirteenth century, beginning fourteenth century. diversity colors accentuated by presence lapis lazuli blue and brazilwood pink, demonstrates desire to produce a sumptuous manuscript. Pink is, this context, luxury color its identifica...

A new chromogenic plate medium, CHROMagar Orientation, was evaluated for use in the differentiation and presumptive identification of gram-negative bacilli and Enterococcus species by a multipoint inoculation (replicator) technique. In this study, 1,404 gram-negative bacilli and 74 enterococcal isolates were tested on CHROMagar Orientation. Six control American Type Culture Collection strains w...

Two congenic strains of RCS rats, RCS-p/+ and RCS-c, have been developed that differ from the parental strain at genetic loci affecting pigmentation. Inbred RCS rats are pink-eyed, while RCS-p/+ rats produce segregating litters of pink-eyed (p/p) and black-eyed (p/+) offspring, and RCS-c rats are albinos. All the strains are homozygous for the mutant form of the retinal dystrophy gene. The blac...

AIMS To identify the diversity of pigmented aerobic spore formers found in the environment and to characterize the chemical nature of this pigmentation. MATERIALS AND RESULTS Sampling of heat-resistant bacterial counts from soil, sea water and the human gastrointestinal tract. Phylogenetic profiling using analysis of 16S rRNA sequences to define species. Pigment profiling using high-performan...

Abstract The deterioration of cadmium yellow paints in artworks by Joan Miró (1893–1983) and painting materials from his studios Mallorca (Spain) was investigated. Analysis samples Miró’s paintings paint tubes palettes showed that degraded are composed poorly crystalline sulfide/zinc sulfide (CdS/Cd 1−x Zn x S) with a low percentage zinc, an oil binding medium. Cadmium sulfates were identified ...
