Potential and prospects for utilization of avocado by-products in integrated biorefineries
Bioresour Technol. 2022 Sep 26:128034. doi: 10.1016/j.biortech.2022.128034. Online ahead of print.ABSTRACTThe industrial processing of avocado to extract oil, and produce guacamole or sauces generates enormous quantities of peels and seeds (around 2 million tons worldwide in 2019) without commercially valuable applications. However, various studies have suggested the presence of a wide range of interesting compounds in the composition of these by-products. This review depicts a thorough outline of the capacity of avocado residues to be converted into a portfolio of commodities that can be employed in sectors such as the fo...

Identification of antifungal compounds from avocado rhizobacteria (Bacillus spp.) against Fusarium spp., by a bioassay-guided fractionation approach
Chem Biodivers. 2022 Sep 23. doi: 10.1002/cbdv.202200687. Online ahead of print.ABSTRACTAntimicrobial compounds produced by bacteria have been increasingly acknowledged as an important resource for the control of phytopathogens. In this work, through a bioassay-guided fractionation approach we identify antifungal metabolites produced by two avocado rhizobacteria (INECOL-4742 and INECOL-5927) both members of the Bacillus subtilis/B. amyloliquefaciens species complex, against Fusarium solani and F. kuroshium, causal agent of Fusarium dieback in avocado and other hosts. The n-butanol (n-BuOH) organic extract from INECOL-4742 ...

Oligomeric Proanthocyanidin Complex from Avocado Seed as A Promising α-glucosidase Inhibitor: Characteristics and Mechanisms
In this study, through bioassay-guided isolation of the main α-glucosidase inhibitors in avocado seed, we discovered the major α-glucosidase inhibitor to be avocado seed oligomeric proanthocyanidin complex (ASOPC). Thiolysis and UPLC-DAD-HRESIMS showed the presence of A- and B-type procyanidins, and B-type propelargonidin with (epi)afzelechin as extension unit. Mean degree of polymerization (mDP) of ASOPC was calculated as 7.3±1. Furthermore, ASOPC appeared to be a strong, reversible, competitive inhibitor of α-glucosidase, with IC50 value of 0.1 µg/mL, which was significantly lower than Acarbose (IC50 = 75.6 µg/mL),...

Acetogenin-induced fibrotic heart disease from avocado (Persea americana, Lauraceae) poisoning in horses
Toxicon. 2022 Sep 16:S0041-0101(22)00266-5. doi: 10.1016/j.toxicon.2022.09.007. Online ahead of print.ABSTRACTPoisoning by avocado (Persea americana) has been confirmed in sheep, goats, dogs, rabbits and ostriches. The clinical signs and lesions are attributed to the acetogenin, persin. Little is known regarding the epidemiology, clinical signs, lesions and therapy caused by acetogenin-induced heart damage. During the two-year study, we investigated a horse farm with six horses that often fed themselves with P. americana leaves or mature fruit pulp and skin on the ground. Two horses died, and one underwent necropsy, histop...

Comparative sub-cellular proteome analyses reveals metabolic differentiation and production of effector-like molecules in the dieback phytopathogen Phytophthora cinnamomi
This study highlights the differential metabolism and cellular processes between the sub-proteomes. Proteins associated with metabolism, nutrient transport and cellular proliferation were over represented in the mycelia. The zoospores have a specialised proteome showing increased energy generation geared towards motility. Candidate effectors and effector-like secreted proteins were also identified, which can be exploited for genetic resistance. This demonstrates a better understanding of the biology and pathogenicity of P. cinnamomi infection that can subsequently be used to develop effective methods of disease management....

Avocados, bananas, and pancakes: Does the oocyte maturity ratio predict live birth rates in in vitro fertilization/intracytoplasmic sperm injection?
When I try to explain oocyte maturity to patients in the daily practice of assisted reproductive technology, I often talk about avocados and bananas. Most people can relate to the joy of eating a perfectly ripe banana or avocado and the dissatisfaction of biting into a green banana, a hard avocado, or a mushy version of either. Striving for the perfect ripeness of these fruits [yes, avocado is a fruit (1)] is similar to the quest to harvest oocytes at their “ripest,” most mature point in in vitro fertilization (IVF).
