Invertase has a vital role in ethanol fermentation, especially on sucrose-containing media. In this study, catabolite-resistant mutants of Saccharomyces cerevisiae were isolated through gamma ray mutagenesis with improved productivity of ethanol and invertases. Enzyme productivity of mutant yeast was compared with that of the parent. Various fermentation parameters were optimized, including substrate...
The complexes of Cu and Mn metals with carboxylates (pivalic acid and benzoic acid) and imidazole were prepared and characterized. The synthesized complexes were screened for antimicrobial activity and cytotoxicity. The FTIR technique was used for characterization. The antibacterial assay revealed that the ligand and complexes are active against Escherichia coli, Staphylococcus aureus and Pasteurella...
Aleyrodidae fly is a vector carrier of various diseases in crops, plants, and vegetables. The present investigation evaluated the Aleyrodidae fly population for its relationship with cotton disease under different environmental conditions. Faisalabad, Chiniot, Sargodha, Jhang, Toba Tek Singh (T. T. Singh), and Burewala from Punjab, Pakistan were selected for this study. The Aleyrodidae fly population...
