Growth and media Liquid cultures were grown at 37°C with aeration in minimal A medium (Miller, 1992) with 0.2% glycerol or glucose as the carbon source or in LB Miller medium (Difco). Colonies were grown at 37°C on 1.5% agar plates made from LB Miller medium or minimal A medium with glycerol as the carbon source. Plasmids were maintained by supplementing media with 50 μg/mL of ampicillin, 15 μg...

This study set out to examine the cystoseira gibraltarica extract (CG) as an environmentally sustainable corrosion inhibitor for carbon steel in 1.0 M HCl medium. The corrosion inhibiting effect has been studied by conventional methods such as gravimetric (weight loss) and electrochemical (EIS and PDP) methods. All the methods used in this study confirm that cystoseira gibraltarica extract has ...

In this study, five Chlorella species (Chlorella vulgaris, Chlorella minutissima, Chlorella pyrenoidosa, Chlorella sp.1 and Chlorella sp.2) were grown in various nutrient medium including BG-11, BBM, Fog's medium and M4N medium for the evolution of biomass and lipid production potential. Among the tested medium, BG-11 was found most economical and efficient medium for all Chlorella species. To ...

bokbunja seed wastes from a wine manufacturing industry were used to prepare carbon for the purpose of using it as an adsorbent for the removal of reactive blue 4 from aqueous solutions. a part of prepared carbon was treated with n-hexane to remove the seed oil present in large amounts in bokbunja seeds. it was found that the hexane treated carbon was more efficient in removing the dye from aqu...

the theoretical and experimental investigation on the thermo-mechanical properties of carbon nanotube (cnt) as reinforcer for oil and gas pipes has increasingly become a hot research area for many engineers and material scientists in recent years. this is mainly due to the advent of the new composite material systems that exhibit exotic material and mechanical properties as compared to the trad...

the effect of different carbon sources on bacterial cellulose production by gluconacetobacter xylinus (ptcc 1734) and two newly isolated strains (from vinegar) under static culture conditions was studied. the production of bacterial cellulose was examined in modified hestrin-shramm medium by replacing d-glucose with other carbon sources. the results showed that the yield and characteristics of ...

in order to reduce the costs associated with poly-β-hydroxybutyrate production, growth and poly-β-hydroxybutyrate production of ralstonia eutropha were studied in batch culture on different carbon sources. experiments were designed and conducted to not only lower the cost of poly-β-hydroxybutyrate production by using inexpensive substrates, but also to increase poly-β-hydroxybutyrate production...

Shoot tips of two fig cultivars (Conadria and Black Mission) proliferated in vitro, were cultured on modified MS medium supplemented with 0.5 mg/l 6-benzylaminopurine (BAP). The present investigation aimed to investigate the effect of different medium salt strengths (Double, full, half and quarter) and different sources of carbon (sucrose and fructose) at different concentrations (0.1 and 0.2 m...

since renaissance, the natural ecosystems have fallen into a complete state ofdisarray due to the rise in the amount of carbon dioxide. soil, the unsparing stuff, is one of themajor sources of carbon storage, and plays a paramount role in the global equilibrium ofcarbon as well as carbon sequestration. given that iran is benefiting from vast steppes, therate of carbon sequestration in them dese...

nowadays microbial biotechnology is considered as one of the most important and profitable branches of industry. in this approach, by using the generator microorganisms, we are able to produce biotechnological products, with higher efficiency. clavulanic acid is being used in combination with commonly used beta-lactam antibiotics in order to fight against bacterial infections that are resistant...
