background: in order to avoid potential harm of synthetic additives food, development of novel functional foods containing natural ingredients is considered in current years. in this study, inhibitory effect of echinophora platyloba essential oil (eo) on growth of aspergillus flavus was evaluated in culture media and cheese. methods: e. platyloba eo was extracted by hydrodistillation method usi...

background: echinococcus granulosus cultivation is very important for improvement of different aspect of medical and veterinary researches. despite many advances in this case, there is a missing link for in vitro life cycle of adult worms and it is fertili-zation. regarding the researchers’ observations, self-fertilization can be done in worms living in dog intestine, but despite all sorts of e...

1. Human placental cord serum contains a factor or factors necessary for active growth of fibroblasts in tissue culture and a factor which prevents the appearance of a characteristic toxicity. 2. The growth-promoting factor(s) is stable to heating to 60 degrees C. for 30 minutes and is associated with the euglobulin fraction of the serum. 3. Extraction of dried cord serum with benzene, chlorofo...

The culture media optimization is an inevitable part of upstream process development in therapeutic monoclonal antibodies (mAbs) production. The quality by design (QbD) approach defines the assured quality of the final product through the development stage. An important step in QbD is determination of the main quality attributes. During the media optimization, some of the main quality attribute...

the present study was carried out to investigate the occurrence of total mycobiota and aspergillus species at different stages of fig production and processing in iran. in the meantime, the potential of different culture media for isolation of fungal species from figs was also investigated. the mycobiota of 389 samples of dried fig were studied. total fungal counts ranged from
