Proteomic analysis of extracellular proteins from Aspergillus oryzae grown under submerged and solid-state culture conditions

Article Abstract:

A comparative proteome analysis of extracellular proteins is carried out under solid-state and submerged culture conditions and protein secretion profiles are determined. A Northern analysis of seven genes from the four groups have indicated that the secretion of alpha-amylase (TAA) and beta-glucosidase (Bgl) are regulated by trapping these proteins in the cell wall in submerged culture and that secretion of glucoamylase A (GlaA) and xylanase G2 (XynG2) are regulated at the posttranscriptional level in the solid-state culture.

Cutinase-like enzyme from the yeast Cryptococcus sp. strain S-2 hydrolyzes polylactic acid and other biodegradable plastics

Article Abstract:

The purified lipase from Cryptococcus sp. strain S-2 is analyzed to determine its amino acid sequence and it is compared with lipases and other related enzymes in the database. The enzyme could effectively degrade the high-molecular-weight compound polylactic acid and also other biodegradable plastics.

Cryptococcus neoformans can utilize the bacterial melanin precursor homogentisic acid for fungal melanogenesis

Article Abstract:

Cryptococcus neoformans strains are found to produce a brown pigment from homogentisic acid (HGA), which is acid resistant and has the electron paramagnetic resonance spectrum of a stable free radical. It is shown that HGA can induce melanization of Cryptococcus neoformans by a fungal laccase.
