During the last 10 years the subject of bacterial spore germination has been intensively investigated. In most of these studies it has been found that bacterial spores are capable of germination under conditions which do not permit the germinated form to survive (Schmidt, 1955; Stedman, 1956). Hills (1949) pointed out that a distinction must be drawn between the requirements for germination and...
objective: the experiment was conducted to evaluate the effect of different levels of germinated barley on performance and egg quality in laying hen. methods: one hundred and twenty laying hens, 44-weeks old, lohmann lsl hens were used in this experiment. birds were assigned randomly to the groups, each of which consisted of 20 birds (4 replicate cages each containing 5 birds). the experiment w...
Objective: Glycine max (soybean) is a legume (Fabaceae) native to East Asia. Glycine max seeds are a powerful stimulant of immune system, used to decrease menopause symptoms, estrogen, treat certain types of cancers including that of the breast, lungs, prostate. It is also used for treating diabetes, liver and kidney disorders. The study aimed to investigate the effect of germinated Glycine max...
Synchronous cultures of Bacillus subtilis 168 M were obtained from light-density spores germinated at 46 C and grown at 37 C. This procedure synchronizes both cell division and chromosome replication. The chromosome synchrony was demonstrated by using transformation to measure changes in marker frequency during the cell cycle. The synthesis of two enzymes and of bacterial flagellar protein was ...
Malate synthase (EC 4.1.3.2), an enzyme unique to the glyoxylate cycle, was purified to homogeneity from cotyledons of 72-hours, darkgrown cotton (Gossypium hirsutum L.) seedlings. Homogeneity of the enzyme was assessed by silver staining SDS-PAGE gels. Purification was accomplished by using a single buffer medium through six steps involving one ammonium sulfate fractionation and chromatography...
Seeds of Aster kantoensis Kitamura (Compositae) were experimentally exposed to different cycles of hydration and dehydration: 3H1D (cycles of 3-d hydration and 1-d dehydration periods), 2H3D, 2H1D, 1H3D, 1H2D, and 1H1D. Under continuous hydration (control), all viable seeds germinated within 9 d. However, all viable seeds exposed to the 3H1D, 2H3D, and 2H1D cycles germinated within 36, 50, and ...
somatic embryogenesis was initiated in c. sativus l. from shoot meristems on ls medium containing bap (2×10-5 m)+naa (2×10-5 m). various stages of somatic embryogenesis were observed in the same medium and the development was asynchronous. somatic embryo development proceeded through well recognized sequences (globular to embryoids) with clearly discernible bipolar regions. matured embryos coul...
