Medium Promoting Sporulation of Bacillus larvae and Metabolism of Medium Components.
A new medium, designated TMYGP broth, was developed that allowed the honeybee pathogen Bacillus larvae NRRL B-3650 to produce up to 5 x 10 spores per ml of culture (microscopic count). This species normally sporulates poorly, if at all, in artificial broth media. An aeration rate lower than that normally used to cultivate other Bacillus species was required for sporulation. During the exponenti...
متن کاملSingle, chemically defined sporulation medium for Bacillus subtilis: growth, sporulation, and extracellular protease production.
The composition and application of a single, chemically defined medium or growth and sporulation of Bacillus subtilis is described. At 37 degrees C cells grew with a doubling time of about 40 min; cultures attained near-maximal spore formation (70 to 80% by 12 h after the end of exponential growth and produced 1 X 10(9) to 2 X 10(9) heat-resistant free spores at 24 h. Dipicolinic acid productio...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Improved medium for sporulation of Clostridium perfringens.
An improved sporulation medium has been developed in which all five strains of Clostridium perfringens tested exhibited a 100- to 10,000-fold increase in numbers of spores when compared with spore yields in SEC medium under comparable conditions. In addition, three of five strains produced a 100- to 1,000-fold increase, with the remaining two strains yielding approximately the same numbers of s...
متن کاملCarbohydrate metabolism of Bacillus larvae.
In recent years considerable attention has been paid to the elucidation of pathways of carbohydrate breakdown differing from that of the well-known Embden-Meyerhof-Parnas (EMP) scheme. Although it is recognized that the stepwise oxidation of glucose via gluconate with or without preliminary phosphorylation is an important means by which a number of aerobic bacteria obtain their energy (Barron a...
