Efektivitas Zat Antibakteri Biji Mimba (Azadirachta indica) untuk Menghambat Pertumbuhan Salmonella thyposa dan Staphylococcus aureus

Neem (Azadirachta indica) is a multifunction plant. Its leaves and seeds can be used as a traditional medicine. One of the benefits of neem seeds is that they can serve as antibacteria. It happens because neem seeds contain certain substances which can impede the growth of Salmonella thyposa and Staphylococcus aureus bacteria. The aims of this research were to find out the efectiveness of soaki...

Mutacins of Streptococcus mutans

The colonization and accumulation of Streptococcus mutans are influenced by various factors in the oral cavity, such as nutrition and hygiene conditions of the host, salivary components, cleaning power and salivary flow and characteristics related with microbial virulence factors. Among these virulence factors, the ability to synthesize glucan of adhesion, glucan-binding proteins, lactic acid a...

Carbazole Alkaloids from Roots of Murraya Koenigii (Rutaceae)

The study on petroleum ether extract of the roots of Murraya koenigii (curry leaf) which involves extraction, separations by using various chromatographic methods and structural determination by spectroscopic techniques have afforded two compounds; 3-methylcarbazole and murrayafoline A. The structure of the compounds were also confirmed by comparison with the previous works. Abstrak. Kajian ter...

Genetic transformation of Streptococcus mutans.

Three strains of Streptococcus mutans belonging to serotypes a, c, and f were transformed to streptomycin resistance by deoxyribonucleic acids derived from homologous and heterologous streptomycin-resistant strains of S. mutans and Streptococcus sanguis strain Challis. Homologous transformation of S. mutans was less efficient than heterologous transformation by deoxyribonucleic acids from other...
