Background Exopolysaccharides (EPS) from mushrooms have many health properties such as anti-tumor effect and immunoenhancing activity. Light-emitting diodes (LEDs) with various light wavelengths (red, yellow, green, blue and white) were applied to study the effects on mycelial growth and EPS production of Pleurotus eryngii. Results In solid-state culture, red and yellow light showed stimulatory effects on P. eryngii hyphal growth. In submerged culture, darkness was the best condition for biomass...

Abstract In this study, Pleurotus eryngii head part waste in a bag-log was collected and processed to yield mushroom hydrolysate powder (MHP). To test its stimulatory effect, a P. eryngii submerged culture was conducted. The prepared MHP (1.6%) and glucose (2%) were found to be the best sources for both mycelial biomass and EPS productions. A specific growth rate of 0.68 day −1 , and a specific EPS yield of 9.55 g/g-dry-cell-weight were obtained under these conditions. It was also found that MHP...

Abstract Fungichromin (FC), a polyene macrolide antibiotic, was found to be useful in the treatment of resistance for plant diseases such as Rhizoctonia damping-off of cabbage and tomato late blight. A novel strain, Streptomyces padanus PMS-702, was employed to study the cultivation conditions for FC production. When using linoleic acid as an additive, a negative effect on FC production was observed. On the contrary, when using oleic acid in concentration of 0.01 M (2.82 g/L), a 3.5-fold enhance...

A reversible ratchet by which Brownian particles can be transported might be attained through the periodic change of a potential in space and time. Since the integrated flow of particles in the ratchet along a certain process can be expressed as a contour integral in the space of potential parameters, it is possible, therefore, to investigate what kind of process has a better net flow of particles in a reversible ratchet system. In a certain process, we study the behavior of the particle flow in...

Abstract Light-emitting diodes (LEDs) with various light wavelengths (red, yellow, green, blue and white) and various levels of light intensity (750, 1500 and 3000 μmol m −2 s −1 ) are applied to study the effects of light sources on chlorophyll a (Chl) and phycocyanin (Phy) production of Spirulina platensis . Logistic rate equations are used to depict the kinetic behavior of algal growth and pigments formation under various light sources and intensities. According to the regression results, a r...

Grifola umbellata (Fries) is one of the most widely used traditional Chinese medicinal mushrooms, and has been termed as Polyporus umbellatus or Chuling in the scientific reports [1-2]. It was noted that polysaccharide from G. umbellata possesses outstanding anti-tumor effects [3]. In this study, the effects of cultural condition on the mycelial growth and exopolysaccharide (EPS) production were studied. Various carbohydrates such as sucrose, lactose, and xylose added into the basal medium as ca...

Abstract In this study, various types of reactors were employed to investigate chitinolytic enzymes production via Paenibacillus taichungensis . It was found that the net-draft tube air-lift reactor (ALNR) gave the best performance among the reactors. Different aeration conditions of ALNR were carried out to evaluate cell growth and chitinolytic enzymes production. It was found that a 2 vvm aeration produces an optimal chitinolytic enzymes activity level of 21.1 mU/mL, which was 2.6 times greate...

Abstract In this study, an approach to prepare immobilized metal affinity membrane (IMAM) with high metal ions and protein adsorption capacities was developed. In the process of coupling epichlorohydrin (EPI) to the regenerated cellulose membrane (RC membrane), NaOH concentration is found to be the most critical. With a lower NaOH concentration, only a minimal amount of EPI reacted to the RC membrane. When NaOH concentration was higher, the membrane was distorted, which caused a significant pres...

In this study, various additives including organic acids, alcohols, vegetable oils, surfactants and polymers were added in the cultural medium to investigate their stimulatory effects on Grifola umbellate mycelia growth and exopolysaccharide (EPS) production. It was found that the commonly used stimulatory additives, effective in other mushrooms’ cultures, exhibited negative results in Grifola umbellata submerged culture. In contrast, the polymer additive, polyethylene glycol (PEG), displayed an...
