（1）分離細菌時，在培養基中加入濃度為50U/ml制霉菌素，可以抑制霉菌和酵母菌的生長。
（2）分離放線菌時，在樣品中加入0.05%十二烷基磺酸鈉（SDS）不僅可以抑制細菌的生長，還能激活放線菌孢子的萌發。加入氟哌酸（5mg/L）+制霉菌素（50mg/L）+青霉素（0.8mg/L）也可以有效地抑制細菌和真菌，而不影響放線菌的生長。
（3）分離霉菌和酵母菌時，在培養基中加入青霉素、鏈霉素和四環素各30U/ml，可以抑制細菌和放線菌生長。
（4）分離根霉和毛霉時，由于這些微生物的菌絲易蔓延成片，難以得到純化的菌落，通常在培養基中添加0.1%去氧膽酸鈉或山梨醇防止菌絲蔓延，使菌落長得小而緊密。
一般用于分離單一目的微生物的培養基中均含有抑制其他微生物的抑制劑，這些專用的抑制劑在小型實驗室配制較麻煩，現已有成品供應，只要直接加入基礎培養基即可。如氨芐西林，主要用于分離親水氣單孢菌。

Formula of common microbiological medium
(1) when separating bacteria, adding concentration of 50U/m in the culture medium; (2) adding 0.05% twelve alkanes in the samples when separating actinomycetes; (3) when separating fungi and yeast, adding penicillin to the culture medium, and (4) separating Rhizopus and Mucor, because the mycelium of these microbes is tendril; it is generally used to separate the single order. The culture medium of microbes all contain inhibition of it; 1, bacterial culture medium; formula a beef paste agar medium; beef cream 0.3 grams, peptone 1 grams, sodium chloride 0.5 grams, water 1000 ml; in the burning of 1000 ml;
(1) when the bacteria were isolated, adding 50U/ml to nystatin in the medium could inhibit the growth of mold and yeast.
(2) when separating actinomycetes, adding 0.05% sodium alkyl sulfonate (SDS) in the sample can not only inhibit the growth of bacteria, but also activate the germination of actinomycetes spore. The addition of norfloxacin (5mg/L) + nystatin (50mg/L) + penicillin (0.8mg/L) can also effectively inhibit bacteria and fungi without affecting the growth of actinomycetes.
(3) when mold and yeast were isolated, penicillin, streptomycin and tetracycline 30U/ml were added to the medium, and the growth of bacteria and actinomycetes could be inhibited.
(4) when Rhizopus and Mucor are separated, the mycelium of these microbes is easy to spread to pieces, and it is difficult to get the purified colony. It is usually added 0.1% deoxycholate or sorbitol to prevent the spread of mycelium in the culture medium, so that the colony grows small and tight.
The culture medium used for isolation of single purpose microbes contains inhibitors that inhibit other microorganisms. These special inhibitors are more troublesome in small laboratories and are now available to the base medium as long as they are directly added to the basic culture medium. Ampicillin, for example, is mainly used for the isolation of monospora hydrophila.
