The computer analysis of primary structures for inulinases from various producers [PDF]

Компьютерные исследования и моделирование, 2011
It is shown that the basic amount of homologous parts at inulinases from various species is presented by Gln, Asn and Glu residues. Carboxyl groups of Asp and Glu side chains (a part of active center of inulinase) can play the role of contact groups for ...

Screening and Characterization of Thermostable Amylase‐Producing Bacteria Isolated from Soil Samples of Afdera, Afar Region, and Molecular Detection of Amylase‐Coding Gene

International Journal of Microbiology, Volume 2021, Issue 1, 2021., 2021
Studying thermostable amylase‐producing bacteria in extreme environments has a crucial role to overcome different industrial challenges. Afar Region is one of the hottest and salty areas, making it the home of extremophiles. This study aimed at screening and characterizing amylase‐producing bacteria isolated from soil samples of Afdera, Afar Region ...

Cloning, Expression, and Characterization of Xylanase G2 from Aspergillus oryzae VTCC‐F187 in Aspergillus niger VTCC‐F017

BioMed Research International, Volume 2021, Issue 1, 2021., 2021
The study focuses on engineering of recombinant Aspergillus niger to produce highly active xylanase. The xylanase G2 encoding gene originating from Aspergillus oryzae VTCC‐F187 was cloned, amplified, and inserted into the pAN7.1GluA vector with specific primers possessing BamHI. The recombinant plasmid was introduced into Aspergillus niger VTCC‐F017 by

Commodity risk assessment of Ficus carica plants from Israel

EFSA Journal, Volume 19, Issue 1, January 2021., 2021
Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers the plant health risks posed by the following commodities: i) dormant and ...

A Feed Additive Containing Encapsulated 6-Phytase within Recombinant Yarrowia lipolytica Cells Produced by Cultivation on Fat-Containing Waste

Applied Sciences, 2022
Feed phytases are purchased as a dry culture medium of secreting producers, mostly micellar fungi. These preparations are required to withstand heating up to 75–80 °C because they are intended for mixing with feed components with subsequent granulation ...

Molecular and kinetic properties of Aspergillus ficuum inulinases.

Agricultural and Biological Chemistry, 1990
The beta-fructosidases from the thermotolerant fungus, A. ficuum, were characterized. All were active as to inulin and sucrose hydrolysis with different specificity constants (kcat/Km). The enzymes were classified according to the ratio (alpha) of the specificity constants for inulin (I) and sucrose (S).

Regulation of the Formation of Acid Phosphatases by Inorganic Phosphate in Aspergillus ficuum [PDF]

Journal of Bacteriology, 1969
Two types of extracellular acid phosphatases are synthesized by Aspergillus ficuum NRRL 3135: a nonspecific orthophosphoric monoester phosphohydrolase (EC 3.1.3.2) with an optimum p H of 2.0, and an enzyme with restricted specificity, a mesoinositol-hexaphosphate phosphohydrolase (EC 3.1.3.8;
