OThis esterification reaction is reversible, however, and the presence of water can lead to hydrolysis of the aspirin.Thus, an anhydrous (“without water”) reagent could lead to better yields of product. This reagent is acetic anhydride.Acetic anhydride is a clear,[r]

Về nguyên tắc trong môi trường có nồng độ rượu đủ lớn, màng vi khuẩn sẽ phát triển không ngừng. Nếu tốc độ tăng của bề dày màng này không lớn lắm thì profile nồng độ trong chúng ở một thời điểm bất kỳ sẽ được xem gần giống như trong lớp vi sinh vật có bề dày không đổi. Khi đó, có thể mô tả cặn kẽ sự[r]

Bacterial species belonging to Shewanella, Vibrio, Flexibacter, and Halomonas (Salunkhe et al., 2011) are known to produce EPA as a major long-chain polyunsaturated fatty acid. EPA is synthesized de novo in a polyketide biosynthesis mode by the enzyme complex consisting of PfaA, PfaB,[r]
