Proteolytic and lipolytic potential of Pseudomonas spp. from goat and bovine raw milk

Abstract: Pseudomonas, the main genus of gram-negative microorganisms isolated from milk, is psychrotrophic, biofilm-forming, and thermo-resistant deteriorating enzyme producers. The aim of this study was to quantify Pseudomonas spp. in goat’s and cow’s milk produced in the Paraná state, Brazil, to evaluate the deteriorating activity of the isolates at mesophilic and psychrotrophic conditions and to identify, at the species level, the isolates with alkaline metalloprotease (aprX gene) production potential. Microbiologic… Show more

“…They are Gram-negative bacteria, usually aerobic, but can be facultative anaerobes ( 7 9 ). While some Pseudomonas species can be associated with pathogenicity, some species have been applied as bioremediation agents ( 5 , 10 14 ), and some are known for their dairy spoilage potential, such as Pseudomonas fragi , P. lundensis , and P. fluorescens ( 15 , 16 ).…”

“…The substrate was fermented for at least 72 hours until the substrate produced oil. Then, the substrate was dried under the sun, and the oil was separated from the 3Bio Journal of Biological Science, Technology and Management 3(1): [18][19][20][21][22][23][24][25][26][27] Edwar et Aditiawati pulp using a press machine. Sampling was done every 24 hours during fermentation stages (sample I=0 h, sample II=24 h, sample III=48 h, and sample IV=72 h).…”

“…The formation of compounds that plays a role in flavours during fermentation can occur through the metabolism of flavour precursor compounds or flavour compounds themselves by microorganisms [22]. In general, the 3Bio Journal of Biological Science, Technology and Management 3(1): [18][19][20][21][22][23][24][25][26][27] Edwar et Aditiawati compounds that play a role in flavour formation can come from groups of amino acids, phenols, and ketones [23]. Amino acids have a vital role in the formation of flavour.…”
