The objective of this research was to investigate biodegradation of water hyacinth (Eichhornia crassipes) to produce bioethanol using dilute-acid pretreatment (1% sulfuric acid) results in high hemicellulose decomposition and using yeast (Pachysolen tannophilus) as bioethanol producing strain. A maximum ethanol yield of 1.14g/L with coefficient, 0.24g g; productivity, 0.015g lh was comparable t...
The scale-up criterion of constant oxygen mass transfer coefficient (kLa) was applied for the production of itaconic acid (IA) in a 50 L pilot-scale fermentor by the fungal cells of Aspergillus terreus. Various operating conditions were examined to collect as many kLa data as possible by adjusting the stirring speed and aeration rate in both 5 L and 50 L fermentor systems. In the fermentations ...
METHODS: An open-label, non-comparative 12 week prospective study conducted in 4 U.S. centers evaluated the safety and effectiveness of SPHAL in conjunction with a blunt-tipped cannula. Adverse events (AEs) were collected throughout the study. Subjects reported predefined, expected post-treatment injection site reactions during the first 2 weeks post-treatment via diary. Effectiveness assessmen...
Gram-positive facultative anaerobic microorganisms that produce large amounts of lactic acid. LAB, which are seen in milk and the human intestine, are used for the manufacture of yogurt and cheese. They are referred to as animal-derived LAB. On the other hand, LAB exist on the surface of fruits, vegetables, and flowers. These LAB, designated plant-derived LAB, have higher adaptation characteris...

polygalacturonase production under different shear stress environments by aspergillus sp. was studied. it was found that the rate of enzyme production in the stirred tank fermentor decreased with increasing the stirrer speed in the range 300-750 rpm. on the other hand, in a split cylinder air-lift fermentor, the rate of polygalacturonase production slightly increased with increasing in air rate...
Batch and continuous production of the extracellular heme glycoprotein chloroperoxidase (CPO) was studied with an airlift fermentor. We induced Caldariomyces fumago CMI 89362 to form pellets by transferring a small inoculum volume in preculture prior to growth in a 1-liter fermentor. Continuous replacement of the fructose-salts medium (dilution rate, 0.008 h) supported continuous CPO formation ...
Lactococcus lactis, the model lactic acid bacterium (LAB), is a food grade and well-characterized Gram positive bacterium. It is a good candidate for heterologous protein delivery in foodstuff or in the digestive tract. L. lactis can also be used as a protein producer in fermentor. Many heterologous proteins have already been produced in L. lactis but only few reports allow comparing production...
