Production of Polyhydroxybutyrate by Bacillus axaraqunsis BIPC01 using Petrochemical Wastewater as Carbon Source

Production of Clavulanic Acid by Streptomyces clavuligerus in Batch Cultures with Using Wheat Bran as the Source of Carbon

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...

Using petrochemical wastewater for synthesis of cruxrhodopsin as an energy capturing nanoparticle by Haloarcula sp. IRU1

In this study, the feasibility of cruxrhodopsin (CR) production as a multifunctional nanoparticle was investigated and optimized by Halorculasp. IRU1, a novel halophile Archaea isolated from Urmia Lake, Iran in batch experiments. In this case, Taguchi method was used for effect measurement of three important factors (petrochemical wastewater, yeast extract and KH2PO4) on CR production. Results ...

Pectinases yeast production using grape skin as carbon source

Pectinases are used in Enology for some different utilities. Enzymatic preparations from moulds are a mixed of different enzymes with strong and unspecific activities. Some Saccharomyces cerevisiae produce pectinases which can be used instead of commercial preparations. The objectives of this work were to study the enzyme secretion by one Saccharomyces cerevisiae (CECT 11783) for growing on gra...

Carotenoid Production by Rhodotorula sp. on Fruit Waste Extract As a Sole Carbon Source and Optimization of Key Parameters

Fruit waste extract was selected as the sole substrate for carotenoid production and the effect of parameters like pH, temperature and agitation have been studied. A two-step simple sequential strategy was employed for the optimization of carotenoid production by Rhodotorula rubra. In the first step, one factor at a time was employed to evaluate the impact of pH on carotenoid production. Th...
