Endophytic bacteria are that live in plant tissue without causing negative effects. can produce bioactive compounds be used as antibacterial, anti-fungal, antiviral, anti-cancer, anti-diabetic, antimalarial and anti-immunosuppressive properties. found all higher plants, one of which is balakacida (Chromolaena odorata). This study aims to isolate the endophytic from Banda Aceh, test antimicrobia...

The use of spectroscopic and spectrometric techniques to isolate, quantify, characterize bioactive compounds from edible plants has become a common mandatory activity in food chemistry. As technology advances, diverse methodologies are being applied more frequently, which coupled most the time give best diagnosis information metabolite interest. In this paper, we state different approaches that...

Screening for bioactive substances has revolutionized the process for identifying novel molecular targets for drug discovery. Such active biological substances have already been generated by nature for millennia but the technical know-how to isolate and characterize them has only been available for a short time. These new possibilities have increased our interest in the establishment of innovat...

milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. the release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...

background and objective: chlorella vulgaris is a multi-cellular edible algal species with abundant proteins. extraction of high value protein fractions for pharmaceutical and nutritional applications can significantly increase the commercial value of microalga biomasses. there is no known report on the anticancer peptides derived from the chlorella vulgaris abundant protein. materials and meth...

BACKGROUND Medicinal plants represent an important opportunity to rural communities in Africa, as a source of affordable medicine and as a source of income. Increased patient awareness about safe usage is important as well as more training with regards to traditional medicine. The aim of this study was to evaluate the ethnomedicinal prowess of some indigenous South African plants commonly used ...

Strains of Beauveria bassiana isolated from locust or from the soil varied considerably in their virulence and their ability to produce in vitro toxic metabolites against Locusta migratoria. Among the pathogenic isolates, only culture filtrates of 90/2-Dm, 92/11-Dm and 0023-Su were toxic by injection, a result which demonstrates that isolates of B. bassiana can be pathogenic for L. migratoria w...

Antibiotics are one of the most important commercially exploited secondary metabolites produced by the bacteria and employed in a wide range. Most of the antibiotic producers used today are the soil microbes. Fungal strains and Streptomyces members are extensively used in industrial antibiotic production. Bacteria are easy to isolate, culture, maintain and to improve their strains. Although tho...

objective: one of the major issues in bone tissue engineering is the design and fabrication of bioactive, bioresorbable porous 3d scaffolds capable of maintaining their structure and integrity over a predictable period of time. one such approach is the fabrication of composite scaffolds. methods: in this study we present fabrication and characterization of novel silk/bioglass-composite scaffold...

Triple-layer omnidirectional reflectors (ODRs) consisting of a semiconductor, a quarter-wavelength transparent dielectric layer, and a metal have high reflectivities for all angles of incidence. Internal ODRs (ambient material's refractive index n >> 1.0) are demonstrated that incorporate nanoporous SiO2, a low-refractive-index material (n = 1.23), as well as dense SiO2 (n = 1.46). GaP and Ag s...
