Two strains of the mold Aspergillus oryzae have been found very satisfactory for producing amylase for use in saccharifying corn fermentation mashes. Best conditions for the production of highly active amylase preparations by growing the molds on wheat bran in rotating drums have been developed and are described. Data are presented for experimental fermentations in which the moldy bran was used...

Differences in extractable b-amylase (1,4-a-D-glucan maltohydrolase, EC 3.2.1.2) activities exist between enzymes from malt and feed barleys (Hordeum vulgare L.). Others have documented few differences in the b-amylase (bmy1) gene coding regions and large differences in the non-coding regions of genomic DNA for endosperm specific b-amylases from malt and feed barleys. Researchers correlated dif...

J. Inst. Brew. 113(2), 147–153, 2007 Fungal hydrophobins have been shown to induce gushing of beer. In order to study the occurrence and fate of hydrophobins at different stages of the production chain of beer, barley samples artificially infected in the field with Fusarium culmorum, F. graminearum and F. poae were collected during the growing period as well as during various stages of the malt...

The genome of retroviruses, including human immunodeficiency virus type 1 (HIV-1), consists of two identical RNA strands that are packaged as noncovalently linked dimers. The core packaging and dimerization signals are located in the downstream part of the untranslated leader of HIV-1 RNA-the Psi and the dimerization initiation site (DIS) hairpins. The HIV-1 leader can adopt two alternative con...
