Two Lingnan University Projects Report Measured Results

Hung Yat has worked with Lingnan University’s Science Unit on two projects led by Dr Jack Chi-Ho Ip, Assistant Professor and Presidential Early Career Scholar. Wong Chin Ming is a named collaborator on both.

Tomato leaf spot

A pineapple-waste eco-enzyme was tested in a 30-day field trial on infected tomato plants. Lesion area fell by 74.6%, and chlorophyll content and photosynthetic efficiency (Fv/Fm) were restored to healthy levels. Sequencing showed the treatment enriched beneficial bacteria (Pseudomonas, Bacillus and Paenibacillus) and suppressed the Mycosphaerellaceae family and Cladosporium.

Fish feed from fermented fruit waste

The LNG-Fisheries Enhancement Fund (project FEF23101) funded a six-month controlled feeding trial in gilthead seabream, with fermented fruit waste added to the feed. Fish on the treated diet gained 20.3% more weight by week 10 than the control group. Glutathione reductase was 96.4% higher and malondialdehyde, a marker of oxidative damage, was 83.4% lower.

Two projects, two results

The projects ran on different timelines with different species, so their results are reported separately and are not comparable. Full write-ups: tomato leaf spot and fruit-waste aquafeed.
