NEW PUBLICATION – Bacteria found to corrode carbon steel

In our latest publication, Yajie Chen, Johanna Torres, Homero Castaneda, and Lu-Kwang Ju demonstrate that nutrient starved Desulfovibrio vulgaris (a sulfate reducing bacterium) is more corrosive than sea-water-level chloride under anaerobic condition. Neither the bacteria nor chloride caused significant steel weight loss (corrosion). However, when the bacteria is starved of …

NEW Publication – Sugar Alcohol to Save Teeth

In this new research, Abdullah Al Loman and Dr. Lu-Kwang Ju conclude that arabitol (a low calorie alternative sweetener) can prevent bacteria from causing tooth damage (dental carries).  Streptococcus mutans, Streptococcus salivarius and Streptococcus sobrinus, Lactobacillus acidophilus, and Lactobacillus fermentum were tested (common oral bacteria). Inhibition to was first tested with 1% arabitol and glucose as the …

New Publication – Stationary phase cellulase production to save 60% of cost

We have found a way to reduce the cost of cellulase by up to 60% by creating a stationary phase cellulase production.  Cellulase is a critical enzyme used in biofuel, textile, and paper industries.  Typically, this enzyme is made by growing a fungus, Trichoderma reesei, in a submerged or solid state fermentation.  The …
