Scientific Study from the year 2014 in the subject Biology - Micro- and Molecular Biology, grade: A, Nirma University (Institute of Science), course: M.Sc., language: English, abstract: This study attempted at microwave mutagenesis of: (i) Lactobacillus plantarum for lactic acid overproduction, and (ii) Streptococcus mutans for reduced lactic acid production. Lactic acid is among the microbiological products with high market potential. Lactic acid is also an important virulence factor in formation of dental caries by S. mutans, as the acid produced by the bacteria leads to demineralisation of...

Scientific Study from the year 2014 in the subject Biology - Micro- and Molecular Biology, grade: A, Nirma University (Institute of Science), course: M.Sc., language: English, abstract: Objective: To investigate the effect of (i) seed extracts of Pongamia pinnata, Pyrus pyrifolia, and Manilkara hexandra, (ii) bacterial pigment prodigiosin, and (iii) three organic solvents (ethanol, methanol, and DMSO), on quorum sensing (QS) in Chromobacterium violaceum. Methods: C. violaceum was challenged with plant extracts prepared by microwave assisted extraction (MAE) method, prodigiosin, and organic...
