the effect of soxhlet and simple immersion extraction methods on the amount and type of bioactive phenolic compounds of c. arizonica woodknots were studied. lipophilic and hydrophilic compounds were soxhlet extracted according to t280 pm-99 standard method with hexane and acetone solvents, respectively.  also, in the immersion method woodknot samples were dipped in hexane to remove the lipophil...

Present study highlights on isolation of bioactive peptide from the sesame protein hydrolysate with an objective of better utilization sesame meal. Sesame protein isolate was enzymatically modified to prepare sesame protein hydrolysate using enzyme ‘Protease A Amano 2G’ in an enzyme membrane reactor and the hydrolysate was subsequently fractionated by ultrafiltration using membranes of decreasi...

Honey acts as an antibacterial without side effects, and also contains antiseptic substances which function to inhibit bacterial growth. This study aimed isolate the Lactic Acid Bacteria (LAB) in Sumbawa white honey bioactive compounds produced pathogenic antibacteria. The 1st stage this was isolation of lactic acid bacteria honey, then continued with a grading test, morphological catalase meth...

Screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. Actinomycetes have the capability to synthesize manydifferent antibiotics. A total of 69 actinomycete isolates were recovered from soil samplescollected from Alborz Province. Selected colonies (rough, chalky) of actinomycetes werepurified. All screened isolates were iden...

This in vitro study evaluated the antimicrobial activity of extracts obtained from Rheedia brasiliensis fruit (bacupari) and its bioactive compound against Streptococcus mutans. Hexane, ethyl-acetate and ethanolic extracts obtained (concentrations ranging from 6.25 to 800 microg/ml) were tested against S. mutans UA159 through MIC/MBC assays. S. mutans 5-days-old biofilms were treated with the a...

The evolving global threat of antimicrobial resistance requires a deep renewal of the antibiotic arsenal including the isolation and characterization of new drugs. Underexplored marine ecosystems may represent an untapped reservoir of novel bioactive molecules. Deep-sea fungi isolated from a record-depth sediment core of almost 2000 m below the seafloor were investigated for antimicrobial activ...

In our screening of marine Streptomycetes for bioactive compounds, in addition to the known metabolites rabelomycin (1), fridamycin D (2b), N-benzylacetamide and N-(2'-phenylethyl)acetamide, two new anthracycline antibiotics designated as himalomycin A (2c) and B (2d) were isolated from the culture broth of the marine Streptomyces sp. isolate B6921. The structure of the new antibiotics was dete...
