Bioactivity of endophytic bacteria and yeasts isolated from Thymus
Endophytes are important resources of bioactive compounds and due to their potential in theproduction of secondary metabolites, they are regarded as a potential reservoir ofbiotechnological applications. In this study, the bioactivity of bacteria and yeasts endophytesresiding in Thymus sp. was evaluated. During April to October 2011, symptomless and healthytissues of Thymus sp. were collected. ...
متن کاملPsychrotrophic bacteria and milk and dairy products quality
The characteristics of microbial populations in raw milk at the time of processing has a significant influence on shelf life, organoleptic quality, spoilage and yields of the raw milk, processed milk as well as on the other dairy products. Unfortunately, cold and extended storage of raw milk, as a common practice in dairy sector today, favour the growth of psychrotrophic bacteria. Therefore, th...
متن کاملCold shock response and low temperature adaptation in psychrotrophic bacteria.
Psychrotrophic bacteria are capable of developing over a wide temperature range and they can grow at temperatures close to or below freezing. This ability requires specific adaptative strategies in order to maintain membrane fluidity, the continuance of their metabolic activities, and protein synthesis at low temperature. A cold-shock response has been described in several psychrotrophic bacter...
متن کاملIncidence of psychrotrophic lipolytic bacteria in cow’s raw milk
The contamination of bulk samples of cow’s raw milk (n = 491) by psychrotrophic lipolytic bacteria (PLiBC), total count of psychrotrophic bacteria (PBC) and mesophilic bacteria (TBC) was monitored for two years on eight dairy farms and the correlations among these groups of bacteria were analysed. An increase in TBC, PBC and PLiBC and in the values of free fatty acids (FFA) was tested experimen...
متن کاملPsychrotrophic bacteria in milk: How much do we really know?
The occurrence of psychrotrophic bacteria in raw milk is studied worldwide due to the difficulties associated with controlling their growth during cold storage and the consequent negative effects upon fluid milk or dairy products. Among the psychrotrophic bacteria, the genus Pseudomonas (represented primarily by P. fluorescens) has been highlighted as the cause of numerous defects in dairy prod...
