Xylooligosaccharides (XOS) and Bacillus subtilis biomass, also regarded as essential prebiotics, have a wide application prospect in feed industry. However, very few studies have reported the coproduction of XOS and Bacillus subtilis from lignocellulosic materials. A XOS yield of 28.8% could be...

Eight previously undescribed triterpenoids, including four dammarane-type triterpenoids, named meliasenans A-D (1-4), four apotirucallane-type triterpenoids, named meliasenans E-H (5-8), along with nine known analogues (9-17) have been isolated from the stem bark of Melia toosendan. The structures...

One of the major limitations of lignocellulose conversion is the relatively low efficiency of cellulases. Expansins can act as an accessory protein to loosen the rigid cellulose structure and promote cellulose hydrolysis. However, the synergistic action of expansin is not well understood. In this...

Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was used to analyze the polymerization distribution of xylo-oligosaccharides from birchwood and beechwood xylans following hydrolysis by the xylanase (XynA) from Bacillus subtilis, which was obtained by...

Acetic acid(AC) hydrolysis and the second-step pretreatment were used to produce xylooligosaccharides(XOS) and enzymatic hydrolysate from poplar. The hydrolysate was used as carbon resource to produce Bacillus subtilis by fermentation. After the poplar was pretreated by 5% AC at 170°C for 30 min,...

Bacteria are becoming resistant to new generation antibiotics day by day, which in turn lead us to find new antibacterial compounds of plant origin. Objective of this study was to assess in-vitro antibacterial activities of methanol extractives of fruits of four plants namely Kleinhovia hospita,...

The present chapter provides knowledge on the ethnopharmacological uses, phytochemistry, and antibacterial potential of Harungana madagascariensis (Hypericaceae). The plant is mainly distributed in tropical Africa and Madagascar, where it has been used in folk medicine to cure several diseases...

Objective: To investigate the relationship between triterpenoid saponin content and antioxidant, antimicrobial, and α-glucosidase inhibitory activities of 70% ethanolic, butanolic, aqueous, supernate and precipitate extracts of Juglans regia leaves. Methods: Triterpenoid saponins of different ...

Emerging evidence of the impact of plant compounds on growth inhibition of micropathogens and cancer cells has opened new areas to evaluate plants' treatment properties. Here, we aimed to investigate in vitro antioxi-dant, antibacterial and anticancer effects of the secondary metabolites iso-lated...

Recently, numerous plant-based synthesis techniques have been used to develop metal nanoparticles. The current study uses the medicinal plant extract of couroupita guianensis (CG) petals to create biogenic silver nanoparticles in an environmentally friendly manner. Different techniques, including...
