In this paper we propose a methodology to determine the structure of the pseudo-stoichiometric coefficient matrix kappa in a macroscopic mass balance based model. The first step consists in estimating the minimal number of reactions that must be taken into account to represent the main mass transfer within the bioreactor. This provides the dimension of kappa. Then we discuss the identifiability...
An unusual phenomenon is observed for gelatin solutions (1.7-6.8%) in the microemulsion system of 0.3 M bis(2-ethylhexyl)sulfosuccinate sodium salt in isooctane and 14.5% distilled water. Highly viscous gels obtained at temperatures above 30 degreesC become free-flowing liquids at low temperatures (5-10 degreesC). This reversible temperature-dependent sol-gel transition phenomenon is used to im...
In this work, mixed-mode silica particles functionalized with octyl and sulfonic acid groups was conveniently prepared by co-bonding a mixture of n-octyltriethoxysilane and 3-mercaptopropyltriethoxysilane and then oxidized with hydrogen peroxide. Candida rugosa lipase (CRL) was immobilized on the mixed-mode silica particles via hydrophobic and strong cation-exchange interaction. The resulting i...
BACKGROUND Agastache rugosa is well-known as a common traditional Chinese medicine, which have relieving summer-heat, analgesic and antipyretic effects, have long been used as folkloristic remedy in the treatment of several infectious diseases, anti-inflammatory, and for its antibacterial properties. Considering the lack of available data on the morphology, anatomy and in vitro activity of A. r...
آنزیم لیپاز از خانواده آسیل هیدرولازها است. این آنزیم قادر به شکستن و تجزیه تری گلیسیریدها و تبدیل آنها به اسید چرب و گلیسرول می باشد. همین امر باعث شده که این آنزیم در صنایع مختلفی مانند مواد غذایی، آرایشی و بهداشتی، تجزیه زیستی، پزشکی، صنایع شیمیایی و صنایع شوینده ها و ... کاربرد داشته باشد. آنزیم لیپاز را می توان از منابع گیاهی، جانوری و میکروارگانیسم ها تهیه کرد. با توجه به کاربرد وسیع این...
The CLSI Antifungal Subcommittee followed the M23-A2 "blueprint" to develop interpretive MIC breakpoints for anidulafungin, caspofungin, and micafungin against Candida species. MICs of < or = 2 microg/ml for all three echinocandins encompass 98.8 to 100% of all clinical isolates of Candida spp. without bisecting any species group and represent a concentration that is easily maintained throughou...
A method based on ultra performance liquid chromatography with a diode array detector (UPLC-DAD) was developed for quantitative analysis of five active compounds and chemical fingerprint analysis of Rosa rugosa. Ten batches of R. rugosa collected from different plantations in the Xinjiang region of China were used to establish the fingerprint. The feasibility and advantages of the used UPLC fin...
