Screening of nonfilamentous bacteria for production of cutin-degrading enzymes
Article Abstract:
A large number of nonfilamentous bacteria was screened for their ability to produce cutinase. A total of only three strains of Pseudomonas aeruginosa (1499A, K799 and DAR41352) showed cutinase activity, which was determined by a novel high performance liquid chromatography technique. Cutinase and esterase production by strains K799 and DAR41352 during the stationary phase were induced by the presence of cutin in the medium. The cutinase activity of strain 1499A was inhibited by the detergent n-octylglucoside.

Topical application of ice-nucleating-active bacteria decreases insect cold tolerance
Article Abstract:
The effects of topically applied or ingested ice-nucleating-active bacteria on the lady beetle's capacity to supercool were investigated. The results showed that at concentrations in the range of 10(super 4) Pseudomonas syringae cells per milliliter, topical application induced freezing at higher temperatures than ingestion. The overall effect of this is to increase the mean supercooling point, leading to a decrease in the insect's cold-resistance.

Effect of temperature oscillation on insect cell growth and Baculovirus replication
Article Abstract:
The effects of temperature oscillation on the formation of occlusion bodies (OB) and the generation of extracellular virus (ECV) are investigated using the sf9 insect cell line derived from Spodoptera frugiperda infected with baculovirus in stationary and suspension cultures. Temperature oscillations from 24 to 28 degrees Celsius enhanced cell viability and increased OB formation and ECV titers in stationary and suspension cultures.
