Safety evaluation of the food enzyme xylanase from a genetically modified Bacillus subtilis strain TD160(229)

EFSA Journal, 2018
The food enzyme considered in this opinion is an endo‐1,4‐β‐xylanase (EC 3.2.1.8) produced with a genetically modified Bacillus subtilis strain from Puratos N.V. (Belgium). The genetic modifications do not raise safety concerns.

Safety evaluation of the food enzyme endo‐1,4‐β‐xylanase from Bacillus subtilis (strain XAS)

EFSA Journal, 2019
The food enzyme is an endo‐1,4‐β‐xylanase (4‐β‐d‐xylan xylanohydrolase; EC 3.2.1.8) produced with the genetically modified Bacillus subtilis strain XAS. Antibiotic resistance genes are present in the production organism on a self‐replicative vector.

Optimization of pH as a strategy to improve enzymatic saccharification of wheat straw for enhancing bioethanol production

Journal of Analytical Science and Technology, 2020
In this work, wheat straw (WS) was used as a lignocellulosic substrate to investigate the influence of pH on enzymatic saccharification. The optimum enzymatic hydrolysis occurred at pH range 5.8–6.0, instead of 4.8–5.0 as has been widely reported in ...

Second‐Generation Polyhydroxybutyrate Production From Pretreated Corn Lignocellulosic Fraction as a Strategy to Repurpose by Products From the Corn‐Processing Chain

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Lignocellulosic residues are non‐cost, non‐edible, renewable feedstocks that can be used in polyhydroxybutyrate (PHB) production. PHB is a bioplastic synthetized by microorganisms, formed intracellularly under stressful growth conditions; however, its production costs are high, representing the major drawback for fossil‐based plastics ...
