Production of bikaverin has been examined in 130Fusarium isolates belonging to 21 species. The highest yield of bikaverin was produced on autoclaved rice - up to 2.5g/kg of dry culture. Bikaverin was produced by the following species:F verticillioides, F sacchari varsubglutinans, F proliferatum, F anthophilum, F oxysporum, F dlamini, F nygamai, F napiforme, andF solani. SpeciesF coeruleum, F poae, F sporotrichioides, F tricinctum, F chlamydosporum, F culmorum, F graminearum, F cerealis (F crookwellense), F avenaceum, F acuminatum, andF equiseti did not produce bikaverin.The production of bikaverin determines the colour of the mentionedFusarium species cultures on agar media and on rice. The pigment has indicator properties and changes colour from red in acidic solution to violet-blue in alkaline. The role it plays in fungus metabolism is not elucidated.
已经对属于 21 个种的 130 株尖孢镰刀菌进行了比克维因的生产研究。在高压灭菌的大米上培养，比克维因的最高产量可达每公斤干培养物 2.5 克。产生比克维因的以下物种有：F verticillioides、F sacchari varsubglutinans、F proliferatum、F anthophilum、F oxysporum、F dlamini、F nygamai、F napiforme 和 F solani。而 F coeruleum、F poae、F sporotrichioides、F tricinctum、F chlamydosporum、F culmorum、F graminearum、F cerealis (F crookwellense)、F avenaceum、F acuminatum 和 F equiseti 这几种物种则不产生比克维因。比克维因的产生决定了所提到的镰刀菌在琼脂培养基和大米上的培养物的颜色。该色素具有指示剂的特性，在酸性溶液中呈红色，在碱性溶液中呈紫蓝色。它在真菌代谢中的作用尚未阐明。
