Yeast-Based Insect Rearing Solutions

Lallemand present recent news from the insect farming industry in a report from the Insectinov-4 congress.

Findings by David Guerrand, Business Director at Lallemand Bio-Ingredients, and Achille Leplat, Technical Support Manager at Lallemand Animal Nutrition.

Almost 10 years after the first Insectinov event in 2014, the French ADEBIOTECH think-tank organized and held Insectinov-4 in Paris, on April 26th 2022 Beta Buzz contributor Lallemand joined the organizing committee and presented recent biotech solutions for insect farming. With close to 80 participants, Insectinov-4 focused on larvae production. Large established insect producers and suppliers were present as well as smaller players from France, Spain and other countries.

The key subjects presented at the event were:

Christophe Derrien from IPIFF (International Platform of Insects for Food and Feed) reminded attendees that close to 1 billion € has been invested in the European insect farming sector in recent years. Farmed insect production is regulated just as other farmed animals. Moreover, insect proteins can now be used in various applications such as aquaculture, poultry and pets. Four insect species have also received first positive EFSA approval and are now authorized for direct human consumption.

Scape-ups (Ynsect, Innovafeed, Agronutris) were focusing on the sustainability facts of insect protein production, with key benefits in reducing GHG emission when compared to other protein sources. All speakers highlighted the importance of establishing the insect farming facility as close as possible to the feed substrate source.


Achille Leplat – Lallemand, presented an overview of biotech solutions for insect farming performance, such as bacteria and enzymes to improve feed quality and performance, specific inactive yeast to boost the reproduction performance and probiotics for optimal larvae growth.


Christophe Trespeuch from Mutatec presented about the importance of selecting the right feedstock for insect farming, taking into consideration cost, availability, quality, nutritional value, color and sustainability.
Anton Gligorescu, from the Danish Technical Institute (DTI) shared recent results based on pilot scale experiments, comparing different diets over up to 13 generations of Black Soldier Flies (BSF). Interestingly, the DTI work showed a biomass increase over time, indicating the BSF are adapting to the diet they are being fed (The DTI team is also working on breeding programs to adapt BSF to specific waste streams).

Vidar Gundersen, Biomar, presented a global perspective on salmon feed evolution since the 1990s: a shift from a fish meal diet to a growing percentage of plant proteins. The question was what % of proteins in aquaculture farming will be insect proteins tomorrow?

Charles Delannoy, Procidys, made a global review of raw material for insect diets. Producing 2 to 3 million MT of insect protein will require 20 to 40 million MT of crude biomass feed substrate, raising key challenges in terms of availability, access and cost.
