Source Tissue
| Source Tissue | Comment | Organism | Textmining |
|---|---|---|---|
| culture condition | carbon sources such as sucrose, maltose, galactose, lactose, mannitol and mannose inhibit enzyme production. Exogenous cAMP in presence of carbon sources stimulates L-asparaginase enzyme production | Staphylococcus sp. | - |
| culture condition | high L-asparaginase activity is found in cells cultured on L-fructose, D-galactose, sucrose or maltose, and in cells cultured on L-asparagine as the sole nitrogen source | Enterobacter cloacae | - |
| culture condition | L-asparaginase-I is constitutive | Saccharomyces cerevisiae | - |
| culture condition | L-asparaginase-II is secreted in response to N starvation | Saccharomyces cerevisiae | - |
| culture condition | sabourand dextrose broth yields maximum growth and maximum L-asparaginase production | Nocardia asteroides | - |

| additional information | a pH of 7.9, casein hydrolysate (3.11%) and corn-steep liquor (3.68%) are the most significant factors improving the enzyme production process | Pseudomonas aeruginosa | - |
| additional information | enzyme activity is highest during the exponential phase of growth | Rhodotorula mucilaginosa | - |
| additional information | highest L-asparaginase production in 2% proline medium, the lowest L-asparaginase production levels is found in the presence of glutamine and urea as nitrogen sources | Aspergillus tamarii | - |
| additional information | production of high levels of L-asparaginase in solid state fermentation, using agro-wastes from three leguminous crops (bran of Cajanus cajan, Phaseolus mungo, and Glycine max) | Aspergillus niger | - |
| additional information | the lowest L-asparaginase production levels is found in the presence of glutamine and urea as nitrogen sources | Aspergillus terreus | - |
| additional information | the synthesis of L-asparaginase in Escherichia coli W and Escherichia coli K-12 is almost completely suppressed if glucose is added at a concentration of 0.5% to the growth medium. Organic acids and amino acids such as L-leucine and L-methionine enhance production of L-asparaginase. n-Dodecane at 6% increases cell concentration by 12.7% and production of L-asparaginase by 21% to give 60.8 IU/ml in the fermentation medium | Escherichia coli | - |
