the abilities of silybum marianum cell culture to biotransform benzaldehyde to benzyl alcohol in three culture systems were compared. callus cultures of silybum marianum were established from seedlings, and healthy suspensions and immobilized cultures grown on the murashige and skoog medium. s. marianum cells were immobilized in both agar beads and fiber cotton matrixes. benzaldehyde was fed to...
background: the basis of spermatogenesis is the spermatogonial stem cells (sscs). the concentration of sscs is very small. however, a system that supports the proliferation and maintenance of sscs in vitro could be used to preserve and expand sscs numbers as well as increase success in transplantation. it is a new avenue to restore spermatogenesis in azoospermia subjects. objective: proliferati...

هدف از انجام این مطالعه مقایسه دو روش mpn-pcr و mpn-culture در شمارش باکتری لیستریا مونوسیتوژنز تلقیح شده به شیر استریل می باشد. برای انجام این کار تعدادcell/ml 103 از باکتری لیستریا مونوسیتوژنز و نیز باکتری های زمینه ای مختلف به شیر استریل تلقیح شدند. پس از آماده سازی رقت های متوالی، از هر رقت در سه لوله حاوی محیط غنی کننده لیستریا تلقیح شد. پس از 48 ساعت گرمخانه گذاری، برای آزمایش mpn-cultu...
batch culture of ralstonia eutropha using the recycled gas closed circuit culture system was conducted in order to develop a practical fermentation system for industrial autotrophic culture for poly (hydroxybutrate) production. the gas phase of the culture system consisted of substrate gas so that gases in this culture could be recycled as long as the amount of the gas consumed would be repleni...
