WhenMortierella alpina ATCC 32222 was incubated in a glucose salts medium at 25°C the biomass (17.5 g/l) contained 9.62% arachidonic acid which amounted to 54% (w/w) of total biomass lipids. When the glucose concentration in the medium... more
A comparative evaluation of five different cell-disruption methods for the release of recombinant hepatitis B core antigen (HBcAg) from Escherichia coli was investigated. The cell disruption techniques evaluated in this study were... more
M. ZAMFIR, R. CALLEWAERT, P.C. CORNEA, L. SAVU, I. VATAFU and L. DE VUYST.1999.Lactobacillus acidophilus IBB 801 produces a small bacteriocin, designated acidophilin 801, with an estimated molecular mass of less than 6·5 kDa. It displays... more
Plant cell culture provides a viable alternative over whole plant cultivation for the production of secondary metabolites. In order to successfully cultivate the plant cells at large scale, several engineering parameters such as, cell... more
In this study we investigated the effects of carbon and nitrogen sources, and the carbon to nitrogen ratio (C:N) of growth medium on the production of plasmid DNA by pUK21CMVβ1.2 harbouring recombinantE. coli. The results indicated that... more
A rapid method for the determination of fungal glucosamine (GlcN) from Aspergillus sp BCRC 31742 was developed. The hydrochlorination process using microwave effectively reduced reaction time needed for GlcN analysis. The analytical... more
Butyric acid fermentation by Clostridium tyrobutyricum ATCC 25755 using glucose or brown algae as a carbon source was carried out. Initially, different fermentation modes (batch, fed-batch, and semi-continuous) at pH 6 and 37°C were... more
Melanin is a pigment that plays an important role in providing coloration and protecting human skin from the harmful effects of UV light radiation. Human skin color is determined by the type and amount of melanins that are synthesized and... more
Monoclonal antibodies (Mabs) have been used as diagnostic and analytical reagents since hybridoma technology was invented in 1975. In recent years, antibodies have become increasingly accepted as therapeutics for human diseases,... more
Hyaluronic acid (HA) production was metabolically engineered in Lactococcus lactis by introducing the HA synthetic machinery from the has operon of the pathogenic bacterium Streptococcus zooepidemicus. This study shows that the insertion... more
Botryococcus braunii has an outstanding ability to produce lipid; however, it is a slow-growing green microalgae. Statistical optimization of growth media was performed to faster growth and to increase lipid concentration. The effect of... more
In recent years, there has been an interest to useMoringa oleifera as the natural coagulant due to cost, associated health and environmental concerns of synthetic organic polymers and inorganic chemicals. However, it is known thatM.... more
