# Revised safety evaluation of the food enzyme endo‐1,3(4)‐β‐glucanase from the non‐genetically modified Cellulosimicrobium funkei strain AE‐TN

## TL;DR

This paper evaluates the safety of a food enzyme produced by a non-genetically modified bacteria after improvements in manufacturing ensure no live bacteria remain.

## Contribution

The study confirms the safety of the food enzyme endo-1,3(4)-β-glucanase after manufacturing improvements eliminate viable cells of the production strain.

## Key findings

- The production strain was no longer detected in new food enzyme batches after process improvements.
- The Panel concluded the food enzyme does not pose safety concerns under intended use conditions.

## Abstract

The food enzyme endo‐1,3(4)‐β‐glucanase (3‐(1–3;1–4)‐β‐D‐glucan 3(4)‐glucano‑hydrolase; EC 3.2.1.6) is produced with the non‐genetically modified (GM) Cellulosimicrobium funkei strain AE‐TN by Amano Enzyme Inc. The production organism belongs to a species implicated in opportunistic infections in humans. In a previous evaluation, the Panel did not consider the food enzyme safe due to the presence of viable cells of the production strain in the food enzyme. As a follow‐up, the applicant improved the quality assurance system by introducing a pressure check of the microfiltration step of the food enzyme manufacturing process and the production strain was no longer detected in new food enzyme batches. The Panel accepted the results. Based on the new data and the previous evaluation, the Panel concluded that the food enzyme endo‐1,3(4)‐β‐glucanase produced with the non‐GM C. funkei strain AE‐TN does not give rise to safety concerns under the intended conditions of use.
