Starvation response of the marine barophile CNPT-3
Article Abstract:
The response of the marine barophile CNPT-3 to nutrient deprivation, in terms of starvation response and surface attachment, was investigated. The count of culturable cells eventually decreased with concomitant decreases in total cell number, viability count and cell size. Biovolume decreased as the cells changed morphology from rods to cocci. Starved cells had higher rates of attachment at the in situ pressure than at 1 atm, and the attachment rate increased with the duration of starvation. Its membrane fatty acid profile showed an increase in saturated and short-chain fatty acids and a decrease in unsaturated fatty acids.

Starvation-induced thermal tolerance as a survival mechanism in a psychrophilic marine bacterium
Article Abstract:
Starvation being the normal physiological state of copiotrophic, heterotrophic bacteria in oligotrophic marine waters, starvation conditions may be pivotal to providing heat tolerance to psychrophillic carbon-starved cultures of strain Ant-300. Starved and unstarved cells exposed to 17 degrees centigrade were compared with cells maintained at the optimum temperature of 5 to 7 degrees centigrade. Total cell counts, direct viable-cell counts and plate counts monitored showed at that at 17 degrees centigrade, viability was lost within 40 hours.

Detection of Vibrio vulnificus biotypes 1 and 2 in eels and oysters by PCR amplification
Article Abstract:
An extraction method developed for oysters and eels yields DNA that is useful in a PCR amplification of a fragment of the hemolysis gene, specific for Vibrio vulnificus biotypes 1 and 2 DNA. The technique allows the identification of V. vulnificus that occurs naturally in oysters and eels. The DNA extraction, PCR and subsequent gel electrophoresis can be completed in ten hrs for oysters and five hrs for eels.
