Predicting black soldier fly larvae biomass and methionine accumulation using a kinetic model for batch cultivation and improving system performance using semi-batch cultivation.

Global demand for poultry and associated feed are projected to double over the next 30 years. Insect meal is a sustainable alternative to traditional feeds when produced on low-value high-volume agricultural byproducts. Black soldier fly (BSF) larvae (Hermetia illucens L.

Almond by-product composition impacts the rearing of black soldier fly larvae and quality of the spent substrate as a soil amendment.

Background: Insect biomass is a sustainable alternative to traditional animal feeds, particularly when insects are produced on low-value high-volume agricultural by-products. Seven samples of almond by-product (hulls and shells) were obtained from processors in California and investigated for larvae production. Experiments were completed with and without larvae and spent substrate samples were assessed for their potential as soil amendments based on standard compost quality indicators.

Comparison of nutrient removal and biomass production between macrophytes and microalgae for treating artificial citrus nursery wastewater.

Macrophyte (Lemna minor) and microalgae (Chlorella vulgaris and Scenesdesmus quadricauda) were used for treating artificial wastewater mimicking recirculating soilless citrus nursery system discharge in the laboratory environment. L. minor gave a better dry biomass yield (0.
