The release of galactosyltransferase, sialyltransferase, and several glycosidase activities into the growth media from several normal and transformed cell lines was examined. Six of the seven cell lines released galactosyltransferase into their culture media. Only the human leukemia CCRF-CEM cells failed to release demonstrable galactosyltransferase activity. Release of galactosyltransferase ac...

Abstract Background and Objectives Proliferation and differentiation of mesenchymal stem cells (MSCs) in culture media requires the presence of nutrient supplements such as bovine fetal serum (FBS), which increases the risk of prion/xenotic infections. Platelet lysates as a rich source of growth factors and cytokines can replace FBS in cell culture medium. This study aimed to compare the effe...

Objective:Mold contamination of cakes and the possibility of mold growth can pose a serious health problem. Bakery products include various ingredients, which regularly contain molds. These microorganisms on cakes can come from the air, contaminated packaging materials and other sources.Methods: In this study, a total of 500 fungal isolates representing 36 species, were identified from cake sam...

Isolating pure microbial cultures and cultivating them in the laboratory on defined media is used to more fully characterize the metabolism and physiology of organisms. However, identifying an appropriate growth medium for a novel isolate remains a challenging task. Even organisms with sequenced and annotated genomes can be difficult to grow, despite our ability to build genome-scale metabolic ...

Since the work of André Martinet back in the 60’s [7], the notion of ‘economy’ has been accepted as one of the main principles underlying the organization of phonological inventories (hereafter PI). This principle, also named MUAF (‘Maximal Use of Available Features’) by John Ohala [8], states that PI are organized along a few phonetic dimensions that they tend to maximize in terms of number of...

In vitro evaluations of salinity (NaCI) effects on three potato cultivars (Atlanta, Shepody and Shilbilaty ) were investigated with five NaCI levels ( 0, 25, 50, 75 and100 mM) by using single node explants. Significant differences were noticed among the cultivars followed by different NaCl levels. Salinity stress gradually depressed plant growth and root development with increased NaCl concentr...

peanut shelles as a waste of cultivated peanuts are produced in a considerable amount in guilan province, iran, that its compost can be used as an available resource in replacement of peat as growth medium of ornamental plants.this experiment was carried out to determine the possibility using of peanut shells compost as an appropriate medium of dracaena. the control treatment was a medium of pe...

The media definitions used for simulations are given in Table S1. The three minimal media are welldefined; the Tryptone media composition is based on the BD Bionutrients Technical Manual. While most metabolite media components are considered exhaustible, some metabolites are present in excess, which is simulated by returning to a preset concentration at every FBA time step. Certain modification...

Our study was to develop a rapid and successful method for promoting asymbiotic seed germination and growth and development of protocorm like bodies (PLBs) and subsequent plantlets of Phalaenopsis orchid. Four basal media i.e. Murashige and Skoog (MS), half strength MS (½MS), Knudson C (KC) and, Vacin and Went (VW) supplemented with coconut water and peptone were examined for their effectivenes...

 Stevia rebaudiana Bert (Asteraceae) is herbaceous plant with sweet leaves, which are the source of sweetener products. The present study focuses on effects of different combination of plant growth regulators on callus induction, callus cell growth and regeneration and volatile constituents from callus of stevia in tissue culture condition. The results of present study showed callus formation p...
