The participation of the different glucose‐catabolic pathways during germination of Streptomyces antibioticus spores was studied. In dormant spores, glucose is catabolized through the pentose phosphate (PP) and the Embden‐Meyerhof‐Parnas (EMP) pathways, with an active tricarboxylic acid cycle. The relative participation of each catabolic pathway is regulated by germinative or non‐germinative conditions. During spore germination, the pentose phosphate pathway continuously increased in its participation in the glucose catabolism and it was the major glucose‐catabolic pathway in the exponential phase of growth. In addition, it showed the existence of an active tricarboxylic acid cycle in dormant spores, which was being drained for biosynthetic purposes.
