报道了农抗５１０２产生菌同源菌株９０－１１、ＦＲ－００８及ＷＨ－１相互之间融合研究的前期结果。３菌株原生质体制备的适宜酶解温度和时间均为３２℃和１．０～１．５ｈ，但所需溶菌酶量则有异：９０－１１为２～４ｍｇ／ｍｌ，ＦＲ－００８为６ｍｇ／ｍｌ，ＷＨ－１为２ｍｇ／ｍｌ。将各菌株的原生质体在－２０℃下冻存１个月内的相对再生率可维持在７０％以上，２个月以内仍可达６０％以上。以５０％ＰＥＧ１０００诱导融合各组合的融合频率是，９０－１１×ＷＨ－１为１０－２，ＦＲ－００８×－９０－１１以及ＦＲ－００８×ＷＨ－１均为１０－３。 The preliminary results of the study on the fusion of strains of Nongkang 5102 with homologous strains 90-11, FR-008 and WH-1 were reported. 3 strain protoplast preparation of the appropriate temperature and time for the hydrolysis are 32 ℃ and 1.0 ~ 1.5h, but the required amount of lysozyme is different: 90-11 2 ~ 4mg / ml, FR-008 is 6mg / Ml, WH-1 is 2 mg / ml. The relative regeneration rate of the protoplasts of each strain at -20 ° C within 1 month can be maintained at over 70%, and still up to 60% within 2 months. The frequency of fusion for each combination induced by 50% PEG 1000 was 90-2, WH-1 was 10-2, FR-008 × -90-11 and FR-008 × WH-1 were all 10-3.
