Catalytic Reduction of 4-Nitrophenol Using Biogenic Silver Nanoparticles Derived from Papaya (Carica papaya) Peel extract

EXTRACTION AND CHARACTERIZATION OF PECTIN DERIVED FROM PAPAYA (Carica papaya Linn.) PEEL

The aim of study was to extract pectin from papaya peel and study its physico‐chemical characteristics. Pectin was extracted using hydrochloric acid and citric acid, at different time, temperature and pH combinations. Extraction was done at temperatures 60°C, 70°C and 80°C for time 30 mins, 45 mins and 60 mins, and pH 2, 2.5 and 3.0 respectively. Using hydrochloric acid, the yield of pectin was...

Genetic characterization of papaya plants (Carica papaya L.) derived from the first backcross generation.

The limited number of papaya varieties available reflects the narrow genetic base of this species. The use of backcrossing as a breeding strategy can promote increases in variability, besides allowing targeted improvements. Procedures that combine the use of molecular markers and backcrossing permit a reduction of the time required for introgression of genes of interest and appropriate recovery...

Characterization of the lipase from Carica papaya residues Caracterização da lipase de resíduos de Carica papaya

Lipases from vegetable sources have been the focus of intense and growing research. The use of enzymes from plants has the advantage of employing industrial waste products. Brazil is the world’s largest papaya producer and the market for products derived from papaya is growing year after year. In this study, the authors carried out the characterization and partial purification of the lipase obt...

Erwinia papayae sp. nov., a pathogen of papaya (Carica papaya).

Bacterial canker of papaya (Carica papaya) emerged during the 1980s in different islands of the Caribbean. Nineteen strains of Gram-negative, rod-shaped, non-spore-forming bacteria isolated from papaya were compared to 38 reference and type strains of phytopathogenic Enterobacteriaceae and related bacteria. Phylogenetic analysis of 16S rRNA gene sequences showed that the papaya strains belonged...
