EFSA Journal, Volume 24, Issue 7, July 2026.Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Exotoxin production by clinical isolates of pseudomonas aeruginosa [PDF]
Infection and Immunity, 1977 Seventy-five consecutive clinical Pseudomonas aeruginosa isolates were tested for in vitro exotoxin production. Exotoxin was demonstrated in culture filtrates biologically, by its ability to produce characteristic dermonecrotic lesions in guinea pigs, and seriologically, by counterimmunoelectrophoresis (CIE) with rabbit antiserum elicited with purified

ChemNanoMat, Volume 12, Issue 6, June 2026.Stimuli‐responsive strategies to achieve controlled release of protein‐based therapeutic agents into solid tumors. Proteins, enzymes, and peptides have long been recognized as valuable therapeutic agents, particularly in oncology. However, their complex chemical structures render them more sensitive than smaller chemotherapeutic drugs.

Transcription and Expression of the Exotoxin A Gene of Pseudomonas aeruginosa [PDF]
Microbiology, 1987 The exotoxin A genes from Pseudomonas aeruginosa strains PA103 and PAO1 have been independently cloned in a pUC9-derived plasmid. In a non-toxigenic mutant of PAO1 as host, the cloned genes directed the synthesis of intact exotoxin A that expressed ADP-ribosyltransferase activity upon treatment with urea and dithiothreitol.
