Physiological and Morphological Modifications in Immobilized Gibberella fujikuroi Mycelia.

摘要: Constraints created by immobilization conditions modified the physiological behavior and morphological characteristics of Gibberella fujikuroi mycelia in comparison with their development free-cell conditions. G. were immobilized different support matrices (polyurethane, carrageenan, alginate) showed a variety reactions response to microenvironmental factors encountered during after immobilization. The best respect gibberellic acid yield biocatalyst stability was found be an alginate high degree polymerization. most visible effects included changes growth development, appearance, metabolite production, mycelial pigmentation, viability under starvation conditions, induction resting forms when previously subcultured.
