求翻译：在黄色偏白菌落中选取的60株菌株分4批进行低温发酵实验，对比总酸、挥发酸和外观发酵度数值后，挑选出13#、16#、21#、25#、26#、41#、46#、55#共8株产酸较低的菌株进行复筛。是什么意思？

Whitish yellow colonies in the 60 selected strains in four batches at low temperature fermentation experiments, compared to total acid, volatile acid and appearance fermentation degree value, selected 13 #, 16 #, 21 #, 25 #, 26 #, 41 #, 46 #, 55 # total of eight strains with lower acid re-screening.
