Killing of Mycolic Acid-Containing Bacteria Aborted Induction of Antibiotic Production by Streptomyces in Combined-Culture
Co-culture of Streptomyces with mycolic acid-containing bacteria (MACB), which we termed "combined-culture," alters the secondary metabolism pattern in Streptomyces and has been a useful method for the discovery of bioactive natural products. In the course of our investigation to identify the inducing factor(s) of MACB, we previously observed that production of pigments in Streptomyces lividans...

در این مطالعه، عملکرد دو سیستم اکسیداسیون شیمیایی پیشرفته و یک سیستم بیولوژیکی برای حذف آموکسی سیلین در فاضلاب های سنتزیدر غلظت های مشابه با موارد صنعتی مورد بررسی قرار گرفته شدند. مطالعه انجام شده دارای سه بخش متفاوت اکسیداسیون با ازن و اشعه uv، اکسیداسیون با استفاده از نانو فتوکاتالیست tio2 و استفاده از بیوراکتور هوازی لجن فعال با جداکننده های فیزیکی می باشد. در هر بخش، متغیر های متفاوتی متنا...
15 صفحه اولInduction of L-form Bacteria from Bacillus thuringiensis
Induction of L-form bacteria from Bacillus thuringiensis was investigated with the long-term view of their use as targeted biological control agents within plants. L-forms were successfully induced from B. thuringiensis subspecies israelensis 36-3 by preparing pour plates of exponential cultures in L-phase medium (LPM) containing 175 g ml -1 cephalosporin C. The induced L-forms were then subcul...
متن کاملProduction of Antitumor Antibiotic by Streptomyces Capoamus
The present study is concerned with the production of antitumor antibiotic by Streptomyces capoamus in batch fermentation. Antibiotic activity was tested against Bacillus subtilis by cylinder plate method. Different culture media were screened and M3 medium consisting of glucose (10.0 g/L), yeast extract (1.0 g/L), meat extract (4.0 g/L), peptone (4.0 g/L) and NaCl (2.0 g/L) was found to be the...
متن کاملL-Form Colony Production
The ability of 258 strains of Staphylococcus aureus and 132 strains of S. epidermidis to produce L-form colonies in a standard environment was investigated. Production of these colonies by S. aureus was correlated with their phage type. Phage type 7 strains produced L-forn colonies in larger numbers and more consistently than those of phage type 80/81. No L-form colonies were produced by the S....
