REDUCTION OF LAG TIME IN BACTERIAL GROWTH

Relation between the generation time and the lag time of bacterial growth kinetics.

In predictive microbiology, the relation between the lag time (Lag) and the generation time (Tg) is commonly assumed to be proportional, as long as the pre-incubation environmental conditions remain constant. This relation was statistically examined in nine published datasets. For every dataset, it was roughly proportional. However, a more advanced study showed that the ratio Lag/Tg was not tot...

Modelling and parameter estimation of bacterial growth with distributed lag time PhD Thesis by

2010 Acknowledgement The study embraces the last two decades I worked for the Institute of Food Research, UK. For the opportunity to become a research scientist, I am indebted to Dr Terry Roberts, the former head of the Microbiology Department there, who decided that further advances in food microbiology was impossible without a dedicated mathematician.

Modelling and parameter estimation of bacterial growth with distributed lag time

Estimating the bacterial lag time: which model, which precision?

The objective of this work was to explore the large number of bacterial growth models recently proposed in the field of predictive microbiology, concerning their capacity to give reliable estimates of the lag phase duration (lambda). We compared these models on the basis of their underlying biological explanations of the lag phenomenon, their mathematical formulation and their statistical fitti...

synthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate

در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
