Effect of feeding pineapple waste on growth performance, texture quality and flesh colour of nile tilapia () fingerlings.

The study aims to evaluate the effects of pineapples waste on the growth, texture quality and flesh colour of Nile tilapia () fingerlings. Fingerlings were fed with four different levels of pineapple waste diets throughout 56 days, which contain a control group (Diet 1) and experimental diets that formulated with 10% (Diet 2), 20% (Diet 3) and 30% (Diet 4) of pineapple waste. The experimental diet was formulated with rice bran, fish meal, soybean meal, vitamin and mineral premix, vegetable oil and binder to attain 32% dietary protein.

Optimised Production and Extraction of Astaxanthin from the Yeast .

Currently, astaxanthin demand is fulfilled by chemical synthesis using petroleum-based feedstocks. As such, alternative pathways of natural astaxanthin production attracts much research interest. This study aimed at optimising bioreactor operation parameters for astaxanthin production and evaluating strategies for its subsequent extraction.
