Since iron carriers of the host become ineffective in dead tissues, the retention of physiological conditions in isolated fluids and tissues is of crucial importance in studies of the microbial quest for iron. Usually, the maintenance of excised tissues or blood at 3°C during the prepara-...

Microbial redox processes. Different metabolic types of bacteria (denitrifiers, manganese reducers, iron reducers, sulfate reducers, and methanogens) occur at landfill sites. Some of these metabolic types (sulfate reducers and methanogens) can be separated into physiological... 

Ethylene physiology of the plant can be manipulated in a variety of ways. In the past, the use of ethylene was limited to exposure of plants to the gas in containers thus, fleld applications were impractical. This limitation was removed by the discovery and commercial development of ethephon in which the liquid active ingredient, 2-chloroethyl phos-phonic acid, is converted to ethylene by the plant (59). Other means of modifying ethylene physiology have been recognized and discussed (4, 5). It is possible to stimulate ethylene synthesis with auxins (60, 61, 62, 63), abscisic acid (64), defoliants (65), ascorbic acid (66), cyclohexi-mide (66), and iron salts (66), among other compounds. A number of physical, environmental, microbial, and insect stresses increase ethylene synthesis, including moisture stress (67) and air pollutants (68).
