OPTIMIZATION OF THE CULTIVATION CONDITIONS AND THE BASIC MOLECULAR TOOLS FOR ROSEOFLAVIN PRODUCER STREPTOMYCES
Abstract:
Roseoflavin (RoF), and its metabolic precursor 8-dimethylaminoriboflavin (AF), produced by Gram-positive bacteria Streptomyces davawensis and Streptomyces cinnabarinus, reveal a strong antibiotic effect against Staphyloccus aureus, Bacillus subtilis, Bacillus cereus, Micrococcus luteus and other Gram-positive bacteria and could be promising for developing the new effective antibacterial drugs. In this work, we present the optimization of basic molecular tools for S. davawensis including total DNA preparation, PCR amplification of target gene, cell transformation. In addition, the compositions of cultivation media were studied and the optimal cultivation conditions for increased of RoF production have been developed.

Basicity of Aliphatic Amines
To measure the basicity of amines, two conventions are generally used. The first defines Kb as the basicity constant for the deprotonation reaction of water by the amine, as presented in Figure 1. Conventionally, lower Kb indicates higher...
Basic Operations on Signals
Time Reversal mirrors a continuous-time signal about the vertical axis at t=0. This is achieved by substituting t with −t. For example, if a signal x(t) is considered, the time-reversed signal is x(−t). This operation can be graphically represented, showing the mirrored signal.
Basic Concept
Length, which measures the distance traveled by an object, is a fundamental concept in engineering mechanics. We use coordinates relative to a reference point to describe the distance. Length not only helps to describe the...
