Sericostoma pauciflorum Stocks ex Wight(Family Boraginaceae) used against cancer, diabetes and known to be health promoter. Callus cultures have been established from the stem explants on Murashige and Skoog (MS) medium supplemented with 1.5 mg/L concentration of different growth hormone viz. kinetin (Kn), indole 3-acetic acid (IAA) and indole 3-butyric acid (IBA). At 6 weeks of age, these call...

To explore marine microorganisms with medical potential, we isolated and identified marine bacteria from floats, marine algae, animals, and sponges collected from Jeju Island, Korea. We isolated and identified 21 different strains from the marine samples by 16S rRNA analysis, cultured them in marine broth, and extracted them with ethyl acetate (EtOAc) to collect secondary metabolite fractions. ...

Background & aim: Recent researches have been done on effects of plant growth regulators (PGR) on growth and production of different crops whose results indicate the effectiveness of most of these hormones on qualitative and quantitative growth of herbs. The application of regulators and inhibitors of growth on herbs may, in addition to growth, also lead to secondary metabolites stimulation. Ja...

The present study aimed to evaluate optimize the growth and antibacterial activity of endophytic fungi isolated from Tylophora indica. Based on the morphological and molecular characteristic, the isolate was identified as Fusarium solani. Modified liquid medium (M2D) was used as a basal medium for growth and antibacterial activity. The growth and metabolite production were optimized with 4% dex...

Aflatoxin is a mycotoxin and a secondary metabolite, and the most potent known liver carcinogen that contaminates several important crops, and represents a significant threat to public health and the economy. Available approaches reported thus far have been insufficient to eliminate this threat, and therefore provide the rational to explore novel methods for preventing aflatoxin accumulation in...

The worldwide dissemination of multi drug resistant Acinetobacter baumannii strains has caused serious concern and high rate of mortality in recent decades that originate from limited effective antibiotics in the treatment of A. baumannii infections. Myxobacteria are Gram-negative bacteria that are important for their complex lifestyle and production of novel structurally secondary metabolites ...

Microorganisms are the major source for the identification of novel bioactive natural products, which may serve as future lead molecules for drug development to treat infectious and other diseases. However, the research efforts to find suchmolecules have been hampered by high re-discovery rates of known biomolecules and a lack of new innovative screening technologies resulting in reduced screen...

An endophytic fungus isolated from Lannea corammendalica displayed considerable antimicrobial activity. The fungus was identified as Colletotrichum gloeosporioides based on morphological features. The metabolite showed more activity against gram positive than gram negative bacterial pathogens. Antimicrobial activity against Staphylococcus aureus was highest with zone of inhibition 25 mm. The fu...
