<p><em>Fermentation is one of the bioconversion processes to produce anaerobic microbes which are beneficial and can produce enzymes. One of the enzymes that can be produced is lipase. Mixed fruit fermentation is an effort to produce lipase that can be done simply. The purpose of this research is to know the activity of lipase enzyme from mixture of fermented avocado fruit (Persea americana), bananas (Musa paradisiaca) and snakefruit (Salacca zalacca). Lipase enzyme activity is tested by measuring of free fatty acid (FFA) content obtained from olive oil hydrolysis process by lipase enzyme. The results showed the highest activity obtained 17.425 U/ml and the percentage of FFA produced was 12.94%. The highest activity of lipase enzyme was obtained at 45<sup>0</sup>C and pH 6.5. From this research can be concluded that the fermentation of the mixture of avocado, bananas and snakefruit can produce lipase enzyme that has relatively high activity.</em></p><p> </p><strong>Keywords: </strong><em>Fermentation, Lipase, Enzyme Activity, Fruits</em>

Fatty acids in avocado fruit (Persea americana Mill.) are vital composition affecting flavour and nutritive value. Hence, horticulturalists are interested in illustrating the functions of transcription factors on fatty acid accumulation in avocado fruit. In the present study, the APETALA2/ethylene-responsive transcription factor gene, PaRAP2.1, was cloned from avocado mesocarp, and the subcellular localization demonstrated that PaRAP2.1 was located in the cytoplasm and nucleus. The PaRAP2.1 was introduced into Arabidopsis thaliana by Agrobacterium-mediated transformation. Furthermore, PaRAP2.1 were functionally verified its effect on fatty acid biosynthesis. Histological analyses of lipid droplets displayed that the striking difference in the lipid droplets in the mature seeds between PaRAP2.1-overexpressing transgenic and wild-type Arabidopsis thaliana lines were revealed based on confocal microscopy images. Subsequently, fatty acid analyses of PaRAP2.1-overexpressing Arabidopsis thaliana lines displayed the significantly higher contents of fatty acids than those in the wild-type plants. Meanwhile, expression amount of ten genes involving in fatty acid biosynthesis dramatically up-regulated in the mature seeds of PaRAP2.1-overexpressing lines than those of wild-type plants. These results provide a theoretical basis for future research in regard to the function of PaRAP2.1 on fatty acid biosynthesis.

The physicochemical composition of avocado fruit has been well reported, but there is little detail on Chinese native avocado varieties. The present study investigated the morphological characteristics, oil contents, and fatty acid compositions of 16 avocado accessions grown in the tropical and subtropical regions of China. Eight fatty acids were identified and quantified by GC-MS. The major fatty acids of avocado pulp were palmitic, oleic, and linoleic acids, accounting for 78-91% of the total fatty acids content. The analysis of one-way variance (ANOVA) of the data revealed morphological and chemical differences between most of avocado accessions. Moreover, 16 avocado accessions were distinguished through a PCA scores scatter plot and cluster analysis based on fatty acid profiles. The results identified some remarkable characteristics of avocado accessions from different places of collection.

Avocado oil is beneficial to human health and has been reported to have beneficial effects on sensorineural hearing loss (SNHL). However, the compounds in avocado oil that affect SNHL have not been identified. In this study, we identified 20 compounds from avocado oil, including two new and 18 known fatty acid derivatives, using extensive spectroscopic analysis. The efficacy of the isolated compounds for improving SNHL was investigated in an ototoxic zebrafish model. The two new compounds, namely (2R,4R,6Z)-1,2,4-trihydroxynonadec-6-ene and (2R,4R)-1,2,4-trihydroxyheptadecadi-14,16-ene (compounds 1 and 2), as well as compounds 7, 9, 14, 17 and 19 showed significant improvement in damaged hair cells in toxic zebrafish. These results led to the conclusion that compounds from avocado oil as well as oil itself have a regenerative effect on damaged otic hair cells in ototoxic zebrafish.
