In the literature, the polyphenol oxidase (PPO) enzyme has been purified a many times via Sepharose 4B-l-tyrosine-p-aminobenzoic acid affinity column. In order to study PPO purification efficiency, 2-aminophenol and 4-aminophenol were applied as a spacer arm to CNBr-activated Sepharose 4B. The

Invasive mycosis has significantly increased in frequency among immunocompromised hosts leading to excessive morbidity and mortality. The combination of sulfamethoxazole (SMX) and trimethoprim (TMP) has been used extensively for the treatment and prophylaxis of infections by various microbes. The

During a survey of actinobacteria known to suppress the growth of Streptomyces scabies (the causative agent of potato scab disease) in vivo, six new rhamnosylated alkaloids, the solphenazines A-F (1-6), were isolated from a biological control strain of Streptomyces (DL-93). The known rhamnosyl

Post-column catalytic hydrolysis combined with 4-aminobenzoic acid hydrazide derivatization is employed for the determination of both reducing and non-reducing carbohydrates in a variety of complex sample matrices such as dairy products, processed foods and tobaccos. Comparison with refractive index
