Production of Chemicals and Fules - Recombinant DNA technology is also having a significant impact on microbial production of chemicals and fuels. Following are some of the examples of this utility:
(i) genetically engineered strains of Bacillus amylouquefaciens and Lactobacillus casei have been prepared for production of amino acids on a large scale;
(ii) industrially useful bacteria can utilize cheaper feedstocks (substrates) like D xylulose, lignocelluloses or cellulose; for instance, Zymomonas mobilis (normally incapable of using lactose) carrying cellulase gene from Cellulomonas uda has six fold increase in cellulase activity;
