Generation and Characterization of Temperature Resistant Mutant of Recombinant PJ156/CAV-17 Virus
(2007)Previous study revealed that a recombinant virus between poliovirus (isolate PJ156) and coxsackie A virus serotype 17 (CAV-17), namely PJ156/CAV-17, was temperature sensitive. It is well known that two amino acids in 3D ... -
Mutation and Characterization of an Albino Mutant of Monascus sp. Isolated from the Cikapundung River, Bandung
(2007)Monascus sp. isolated from Cikapundung River, Bandung was mutated using ethyl methanesulfonate (2.5%, 90 min). Previously, this wild type was identified as Monascus purpureus ITBCC-HD-F001 employing random amplification ... -
Screening of Lactic Acid Bacteria for the Purpose of Chitin Recovery Processing
(2007)Lactic acid fermentation has been studied as an alternative method of chitin recovery from the natural chitin compounds, such as shrimp waste. The purpose of this research was to identify a potential lactic acid bacterium ... -
Improving the Effectiveness of Crude-Oil Hydrocarbon Biodegradation Employing Azotobacter chroococcum as Co-Inoculant
(2007)Azotobacter chroococcum has a great potential as biosurfactant producing bacteria and was used as co-inoculant to promote the rate of hydrocarbon biodegradation. The rate of hydrocarbon biodegradation were 0.01212, 0.01582, ... -
Hospital Acquired Bacterial Infection in Burns Unit at Cipto Mangunkusumo Hospital, Jakarta
(2007)Burn injury causes mechanical disruption to the skin, which allows environmental microbes to invade the deeper tissues. A prospective study of infections in burn patients has shown that the incidence of hospital acquired ... -
