Raw starch degrading alkaline α-amylase from Geobacillus kaustophilus TSCCA02: Production, characterization, and its potential for application as a detergent additive.

Geobacillus kaustophilus TSCCA02, a newly isolated strain from cassava (Manihot esculenta L.) rhizosphere soil in Thailand, showed maximum raw starch degrading enzyme (RSDE) activity at 252.3 ± 9.

Function of , a homolog, in appressorium formation and cAMP signal transduction in .

A novel homolog of , a global regulatory gene in filamentous fungi, was identified from . A deletion mutant of the homolog () exhibited lowered intracellular cAMP levels, and decreased appressorium formation on non-host surface; the decrease was recovered using exogenous cAMP and IBMX, indicating that deletion affected the cAMP signaling pathway.
