title: Bio-transformation of agri-food wastes by newly isolated Neurospora crassa and Lactobacillus plantarum for egg production.
abstract: Using bio-transferred feedstuff was a cost-effective approach to improve egg quality and production; particularly, the nutritive diet came from agri-food wastes. In this study, optimization of fermentation conditions and co-cultivation of Neurospora crassa with Lactobacillus plantarum was performed in a simple bioreactor. The optimized fermentation of beer lees substrates through N. crassa led to the hydrolysis rates of crude fiber increasing to 43.27%. Compared to that of using N. crassa alone, the combination of N. crassa and L. plantarum enhanced the content of amino acids (13,120 to 18,032 mg/100 g) on oil-tea seed cake substrates particularly. When hens were fed 10% fermented oil-tea seedcake substrate, the ratio of feed to egg decreased from 3.1 to 2.6, egg production ratio increased from 65.71 to 80.10%, and color of vitelline (Roche) increased from 8.20 to 10.20. Fifteen kinds of carotenoids were identified by HPLC in fermented oil-tea seed cake substrates. The results of this study highlighted that the mixed-fermentation by N. crassa and L. plantarum may be an effective way to convert agri-food wastes into high-valued biomass products, which could have a positive effect on hens and their eggs.
