| Summary: | Food supply chain introduces high food wastage and unwanted by-products. Large
amount of waste such as plastic and industrial by products such as seeds are being
generated. These wastes often end up in water bodies such as rivers, oceans, or landfills
to be incinerated which incurs detrimental environmental and economic impacts.
These adverse negative impacts introduced from wastes can be mitigated with a more
efficient upcycling of wastes with the help of the Tenebrio Molitor (Yellow
Mealworm). The Tenebrio Molitor (Yellow Mealworm) have good nutritional content,
a broad range of diet and is a promising bio-converter. The gut-inhabiting
microorganisms play a significant role to provide essential nutrients to mealworm and
is also capable of degrading waste products such as polystyrene (PS) is commonly
studied. There are many forms of food waste, and a large contribution of food waste
comes from the by-products of oil extraction. Globally, the extraction of sesame oil
leads to approximately 1.1 million ton of sesame oil meal (SOM) by-product which
are rich in protein but may also contain anti-nutritional factors. In this study , mizuna,
butterhead lettuce, and lettuce will first be used to observe how gut microbiota is
altered when fed with different feeding substrates. Secondly, the gut microbiota and
growth performance of mealworms fed via feeding inoculation with SOM-digestive
strain isolated from SOM or mealworm guts will be evaluated. The results of this study
suggest that a change in feeding substrate significantly changes mealworm gut microbiota while feeding inoculation method demonstrated potential improvement in
mealworm digestibility to waste products. |
