Characterization of Pseudomonas spp. and Associated Proteolytic Properties in Raw Milk Stored at Low Temperatures
Milk spoilage is caused by the presence of proteolytic enzymes produced by Pseudomonas spp. during storage at low temperatures. The aim of this study was to identify Pseudomonas spp. in raw milk and investigate their associated proteolytic properties at low temperatures. Raw milk samples (n = 87) were collected from 87 bulk tanks in Shaanxi Province in China. Pseudomonas spp. were identified us...
متن کاملMilk-deteriorating exoenzymes from Pseudomonas fluorescens 041 isolated from refrigerated raw milk
The practice of refrigerating raw milk at the farm has provided a selective advantage for psychrotrophic bacteria that produce heat-stable proteases and lipases causing severe quality problems to the dairy industry. In this work, a protease (AprX) and a lipase (LipM) produced by Pseudomonas fluorescens 041, a highly proteolytic and lipolytic strain isolated from raw milk obtained from a Brazili...
متن کاملSome Chemical Changes Exhibited in Sterile and in Contaminated Haddock Muscle Stored at Different Temperatures.
The bio-chemical changes which occur in fish tissues are due to two factors, autolysis and bacterial action. As early as 1903, Muller reported that changes due to autolysis took place when sterile fish tissues were incubated. More recently attention has been focussed on the relative importance of these two causes of bio-chemical change. Reed, Rice and Sinclair (1929) presented evidence that aut...
متن کاملBenzodiazepine stability in postmortem samples stored at different temperatures.
Benzodiazepine (lorazepam, estazolam, chlordiazepoxide, and ketazolam) stability was studied in postmortem blood, bile, and vitreous humor stored at different temperatures over six months. The influence of NaF, in blood and bile samples, was also investigated. A solid-phase extraction technique was used on all the studied samples, and benzodiazepine quantification was performed by high-performa...
متن کاملDraft Genome Sequence of Pseudomonas fluorescens SRM1, an Isolate from Spoiled Raw Milk
Pseudomonas fluorescens is considered a major milk spoilage organism due to its psychrotrophic nature and ability to produce heat-stable proteases and lipases. Here, we report the draft genome and annotation of P. fluorescens SRM1 isolated from spoiled raw milk and the presence of an operon encoding spoilage enzymes.
