Distinctive Bacterial Communities in the Rhizoplane of Four Tropical Tree Spe…

Abstract It is known that the microbial community of the rhizosphere is not only influenced by factors such as root exudates, phenology, and nutrient uptake but also by the plant species. However, studies of bacterial communities associated with tropical rainforest tree root surfaces, or rhizoplane, are lacking. Here, we analyzed the bacterial community of root surfaces of four species of nat…

The Relative Abundance of Mountain Pine Beetle Fungal Associates Through the …

Abstract The mountain pine beetle (MPB) is a native bark beetle of western North America that attacks pine tree species, particularly lodgepole pine. It is closely associated with the ophiostomatoid ascomycetes Grosmannia clavigera, Leptographium longiclavatum, Ophiostoma montium, and Ceratocystiopsis sp.1, with which it is symbiotically associated. To develop a better understanding of int…

Handbook of Water and Wastewater Microbiology

Some 2300 years ago Hippocrates wrote: ‘My other topic is water, and I now wish to give an account both about waters that cause disease and about those that are healthy, and what bad things arise from water and what good things. For water contributes very much to health.’ So our appreciation of a relationship between the water we use and our health has been with us for a very long time. Hi…

Fundamental food microbiology

Introductory food microbiology is a required course for undergraduates majoring in food science.
