Variability in Nutrient Use by Orchid Mycorrhizal Fungi in Two Medium Types

open access: yesJournal of Fungi (Basel, Switzerland), 2023
Orchid mycorrhizal fungi (OMF) from the rhizoctonia aggregate are generally considered to be soil saprotrophs, but their ability to utilize various nutrient sources has been studied in a limited number of isolates cultivated predominantly in liquid media,

Iron Supply in a Nutrient Medium

Botanical Gazette, 1924
1. The iron of ferric tartrate soon becomes converted into insoluble compounds when added to nutrient solutions, and the change is more rapid in solutions of higher PH. 2. The introduction of carbon dioxide lowers the PH of slightly acid, neutral, or alkaline solutions, but does not increase the solubility of iron compounds which they contain. 3.

Nutrient medium and frozen storage of human lymphocytes

Cryobiology, 1975
Abstract 1. 1. Lymphocytes to be used for tissue typing procedures can be stored at room temperature in a nutrient medium for periods of up to 3 wk without an intervening change of fluid medium. 2. 2. Fresh or nutrient medium stored lymphocytes can be frozen in bulk quantities until they are required for tissue typing studies, and/or 3. 3.

The Soil as a Plant Nutrient Medium

2001
Soil is a heterogeneous material consisting of three major components: a solid phase, a liquid phase and a gaseous phase. All three phases specifically influence the supply of nutrients to plant roots. The solid phase is the main nutrient reservoir. The inorganic particles of this phase contain cationic nutrients such as K, Na, Ca, Mg, Fe, Mn, Zn, and ...

Diffusion of Nutrients in a Biphasic Medium for the Cultivation of Trypanosomes

Zeitschrift für Parasitenkunde, 1973
1. Studies on uninoculated, biphasic media, containing 10% defibrinated rabbit blood in an agar base with Locke's solution as an overlay, have shown that diffusion of nutrients from the agar base into the overlay requires about 24–48 hr for equilibration.

[Bacterial diversity in the sediments of Taihu Lake by using traditional nutrient medium and dilution nutrient medium].

Wei sheng wu xue bao = Acta microbiologica Sinica, 2006
Bacterial diversity in the sediments of Taihu Lake was studied by using traditional nutrient medium (NM) and 10-fold dilution of traditional nutrient medium (DNM). Results showed that the amount of the bacteria cultured on DNM was 3-5 times higher of those on NM.

Optimization of nutrient medium for biosynthesis of gibberellic acid

Journal of Basic Microbiology, 1991
AbstractA new method of optimization of the medium composition by biostatistical methods is reported. The well‐known Box‐Wilson scheme combined with the method of optimum curves was applied for an exploration of the response surface. The primary goal has been to optimize the concentration of nutrients for the production of gibberellic acid by the ...
