Reliability of the most-probable-number technique for enumerating rhizobia in tropical soils.
We used six rhizobium-legume systems to test the reliability of the most-probable-number (MPN) technique for enumerating rhizobia introduced into 14 sites representing four soil orders. The range-of-transition values (the number of dilution steps between the first not-entirely-positive and the last not-entirely-negative growth units) were compared for each species and for each soil. The probabi...
متن کاملEcological indicators of native rhizobia in tropical soils.
The relationship between environment and abundance of rhizobia was described by determining the populations of root nodule bacteria at 14 diverse sites on the island of Maui. Mean annual rainfall at the sites ranged from 320 to 1,875 mm, elevation from 37 to 1,650 m, and soil pH from 4.6 to 7.9. Four different soil orders were represented in this study: inceptisols, mollisols, ultisols, and an ...
متن کاملTempo® Most Probable Number Technique for the Enumeration Yeasts and Moulds in Feed and Food Products
The large and diverse group of microscopic foodborne yeasts and moulds includes several hundred species. Both yeasts and moulds cause various degrees of deterioration and decomposition of food. They can invade and grow on virtually any type of food at any time, e.g. they invade field crops such as small grains, nuts, beans, tomatoes, and apples both in the field before harvesting and during sto...

Use of the Most-Probable-Number Technique To Detect Polymyxa betae (Plasmodiophoromycetes) in Soil.
The fungus Polymyxa betae is an obligate parasite of the roots of many plants of the family Chenopodiaceae. In the sugar beet, it acts as a vector of beet necrotic yellow vein virus, the agent of a serious disease known as rhizomania. With indirect methods of analysis, such as bioassay, one can establish only the presence or absence, but not the quantity, of P. betae in soil. A new method based...
