    Notes: Summary A strain of Aspergillus niger adapted to grow on gluconate is cultivated on a medium containing gluconic acid lactone as the sole carbon source. Nutritional requirements of the adapted mold were studied. The organism shows optimum growth at 30° C in a medium containing per litre 20 g of gluconic acid lactone, 800 mg of NH4NO3, 100 mg of MgSO4, 7 H2O and 270 mg of KH2PO4 having pH 2.0. Mycelial growth reaches its maximum on the third day. Comparative growth responses of the adapted and parent strains on gluconate, glucose and sucrose were studied.

    Notes: Summary Phosphogluconate dehydrogenase was purified about 20 fold from an adapted strain of Aspergillus niger cultivated on gluconate as the sole carbon source. The enzyme showed pH optimum between 7.0 to 7.6. The enzyme was activated by glycyl glycine buffer and magnesium ions. Mn++, Ba++, Ca++ cysteine and reduced glutathione activated the enzyme, while Co++, Zn++, Cu++, Hg++, PCMB and monoiodoacetate inhibit the enzyme. K m values for the substrates, 6-phosphogluconate and NADP, were found to be 1.66×10−4 m and 8.3×10−5 m respectively.

    Notes: Summary A citric acid accumulating strain of Aspergillus niger adapted to grow on gluconic acid lactone as sole carbon source was studied with regards to the enzymatic changes occurring during its adaptive growth and compared with those of the parent strain cultivated on sucrose. Glucose oxidase, glucose dehydrogenase, gluconate dehydrogenase and enzymes of Entner Doudoroff pathway could not be detected in the strain. Gluconokinase was detected in the strain and its inducible nature was established. An adaptive increase of gluconokinase, phosphogluconate dehydrogenase and ribose phosphate isomerase was observed. While the levels of the above enzymes were significantly higher, that of glucose 6-phosphate dehydrogenase were significantly low indicating the repression of the enzyme. Levels of hexokinase and fructose diphosphate aldolase remained more or less the same as that of parent strain. It was inferred from the results that gluconate metabolism occurs via the pentose phosphate pathway following initial phosphorylation.
