Characteristics of the vegetative growth of Bacillus popilliae.
Growth characteristics of the insect pathogen, Bacillus popilliae Dutky, were studied by propagation in shaken flasks and in 2-liter fermentors. Maximal populations between 5 x 10(8) and 2 x 10(9) viable cells per milliliter of culture medium routinely were obtained in incubation periods of 18 to 24 hr at 30 C in a medium composed of 1.5% yeast extract, 0.6% K(2)HPO(4), and 0.2% glucose or treh...

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولCharacteristics of the constituent substrains of Bacillus popilliae growing in batch and continuous cultures.
Continuous culture of Bacillus popilliae was achieved for the first time in a small chemostat. Initially, variable cell yields during steady-state chemostat growth led to a re-examination of growth rates in batch cultures. B. popilliae NRRL B-2309 and a wild strain were both found to be natural mixtures of three substrains characterized by different growth rates and colony morphologies and vary...
متن کاملFatty acids in Bacillus larvae, Bacillus lentimorbus, and Bacillus popilliae.
The types of fatty acids produced by two strains each of Bacillus larvae, B. lentimorbus, and B. popilliae, and their distribution patterns, were studied by gas-liquid chromatography. All six organisms produced eight major fatty acids: six branched (iso-C(14), -C(15), -C(16), and -C(17), and anteiso-C(15) and -C(17)), two normal (n-C(14) and -C(16)), and two minor (n-C(15) and monounsaturated n...
متن کاملCharacteristics of a new strain of Bacillus popilliae sporogenic in vitro.
Conditions are described that led to the isolation of NRRL B-2309M, a strain of Bacillus popilliae which sporulates regularly in laboratory culture. Colonies grown on a medium formulated with yeast extract and the ingredients of Mueller-Hinton with phosphate, trehalose, and agar, produced 20% spores in 10 to 12 days. The quantity and kind of yeast extract determine the extent of sporulation, al...
