用0.4%胶态甲壳素加无机盐制成的琼脂培养基（pH8.0）分离和计数放线菌的效果优于其它四种常用培养基（上级）。几丁质琼脂上放线菌生长较多，细菌和真菌生长受到抑制。冷冻和真空干燥的甲壳素从水性胶体悬浮液细分，并给出了结果与从胶体悬浮液制备的介质所获得的。图像
Agar media made with 0.4% colloidal chitin plus mineral salts and adjusted to pH 8.0 was superior to four other commonly used media for the isolation and enumeration of actinomycetes from water samples. More actinomycetes developed on chitin agar, and the development of bacteria and fungi was suppressed. Frozen and vacuum-dried chitin from aqueous colloidal suspensions was finely divided and gave results comparable to those obtained with media prepared from colloidal suspensions. Images
