Human Epidermal Growth Factor (hEGF) is a protein molecule with potent mitogenic activity, increasing the rate of wound and ulcer healing in different tissues of the human body. In recent years, the Center for Genetic Engineering and Biotechnology (CIGB) has carried out projects at the developmental stages for the application of hEGF in novel therapies. It is now necessary to increase productio...
background: recombinant monoclonal antibodies have been marketed in last three decades as the major therapeutic proteins against different cancers. however choosing a proper medium and supplements to reach the high expression is a challenging step. despite of commercial serum free and chemically defined media, there are still numerous researches seeking the optimum media to gain higher expressi...
Biosurfactants (BS) are produced by a variety of microorganisms from renewable resources, and have unique properties compared to chemical surfactants. In order to attain efficient production of BS from low-cost materials, we focused our attention on the use of sugarcane molasses. Fifteen yeast strains that are known as BS producers were examined for BS productivity from a culture medium consist...
The manipulation of nutrient-signaling pathways in yeast has uncovered the impact of environmental growth conditions in longevity. Studies using calorie restriction show that reducing glucose concentration of the culture media is sufficient to increase replicative and chronological lifespan (CLS). Other components of the culture media and factors such as the products of fermentation have also b...
In this study, the degradation potential of five polycyclic aromatic hydrocarbons (PAHs) by aerobic mixed bacterial cultures was investigated. Microorganisms were isolated from hydrocarbon contaminated soils of Shadegan wetland located in southwest of Iran. The degradation experiments were conducted in liquid cultures. PAH or PAHs concentration was 100 mg/L at the beginning of degradation e...
conclusions direct sample pcr has the potential to rapidly and accurately diagnose candida vulvovaginitis in patients, especially if sufficient samples are obtained. results the results showed that out of the 150 samples, 55 were positive and 63 samples were negative by both methods, and 32 samples were positive using the culture method, but negative by ds-pcr. all positive ds-pcr samples had >...
Beta(1,3)/(1,6)-glucans are structural polysaccharides of the yeast cell wall. They exhibit diverse functional properties, including therapeutic, thanks to which they find an application in the pharmaceutical, cosmetic, food, and other industries [23]. They serve as biological modifiers of the immune response. Additionally, they stimulate antimicrobial and anti-inflammatory activities; adsorb m...
The present study is concerned with the improved invertase production by Saccharomyces cerevisiae on kinetic basis. The wild-culture (IIB-1) and putative mutant (NA6) of S. cerevisiae were compared on time course basis when grown in batch culture. The values for Yx/s, Yp/s and Yp/x with urea were significantly improved (p≤0.05) over the control (peptone+yeast extract) as well as peptone supplem...
