Microbial Physiology and Ecology of Slow Growth

Microbial physiology and ecology of slow growth.

The uptake capabilities of the cell have evolved to permit growth at very low external nutrient concentrations. How are these capabilities controlled when the substrate concentrations are not extremely low and the uptake systems could import substrate much more rapidly than the metabolic capabilities of the cell might be able to handle? To answer this question, earlier theories for the kinetics...

Microbial Ecology Exemplifies Building Ecology

Recent advances in molecular methods have dramatically improved knowledge of the microbial communities and their diversity in indoor environments. We have retrieved over 150 references with results of indoor microbial investigations and environmental factors. Representative papers are summarized here. The results show that buildings are complex, ecosystem-like, and that collaboration between mi...

Microbial growth and physiology: a call for better craftsmanship

Virtually every microbiological experiment starts with the cultivation of microbes. Consequently, as originally pointed out by Monod (1949), handling microbial cultures is a fundamental methodology of microbiology and mastering different cultivation techniques should be part of every microbiologist's craftsmanship. This is particularly important for research in microbial physiology, as the comp...

Microbial Ecology of Retail Ready-to-Eat Escarole and Red Chicory Sold in Palermo City, Italy

Background: Ready-To-Eat (RTE) foods include any edible food that is commonly consumed raw. This study aimed at evaluation of microbial ecology of retail RTE escarole and red chicory sold in Palermo city, Italy. Methods: A total of 32 mono-varietal RTE samples, including escarole (n=16) and red chicory (n=16) samples were obtained from Palermo, Italy. Both RTE vegetables at expiry date were an...
