Optimization of nutritional requirements for mycelial growth and sporulation of entomogenous fungus Aschersonia aleyrodis Webber

The objective of the present study was to investigate the optimal nutritional requirements for mycelial growth and sporulation of entomopathogenic fungus Aschersonia aleyrodis Webber by orthogonal layout methods. Herein the order of effects of nutrient components on mycelial growth was tryptone > Ca(2+) > soluble starch > folacin, corresponding to the following optimal concentrations: 1.58% Sol...

Anaerobic Growth of Thiobacillus ferrooxidans.

The obligately autotrophic acidophile Thiobacillus ferrooxidans was grown on elemental sulfur in anaerobic batch cultures, using ferric iron as an electron acceptor. During anaerobic growth, ferric iron present in the growth media was quantitatively reduced to ferrous iron. The doubling time in anaerobic cultures was approximately 24 h. Anaerobic growth did not occur in the absence of elemental...

Anaerobic growth of psychrophilic bacteria.

Upadhyay, J. (Washington State University, Pullman) and J. L. Stokes. Anaerobic growth of psychrophilic bacteria. J. Bacteriol. 83:270-275. 1962.-Facultatively anaerobic psychrophilic bacteria are widely distributed in nature and can be readily isolated from a variety of foods, soil, sewage, and other habitats. Strictly anaerobic psychrophiles, however, could not be isolated. Temperature and ox...

Optimal nutritional intake for fetal growth.

The regular nutritional intake of an expectant mother clearly affects the weight development of the fetus. Assuming the growth of the fetus follows a deterministic growth law, like a logistic equation, albeit dependent on the nutritional intake, the ideal solution is usually determined by the birth-weight being pre-assigned, for example, as a percentage of the mother's average weight. This prob...
