Pseudomonas fluorescens produces pyov______ (yellow-green and fluorescent) and h____-s____ enzymes (li_________ and pr_________ ), which cause milk to spoil, by causing bitterness, ca______ breakdown, and ropiness due to the production of sl________ and coagulation of p_________ .

Pseudomonas fluorescens produces pyoverdine (yellow-green and fluorescent) and heat-stable enzymes (lipases and proteases), which cause milk to spoil, by causing bitterness, casein breakdown, and ropiness due to the production of slime and coagulation of proteins; production of slime → biofilm formation

P. aeruginosa uses si________ that bind and transport i____ for growth, but also help in colonization of p____ r_____ (stimulation of plant growth) and bioactivity against f______phytopathogens

P. aeruginosa uses siderophores that bind and transport iron for growth, but also help in colonization of plant roots (stimulation of plant growth) and bioactivity against fungal phytopathogens

-> Utilization of sideromycins in antibiotic therapies (siderophores + antibiotics → Tojan horse strategy)
