Agave - Science topic

A genus known for fibers obtained from their leaves: sisal from A. sisalana, henequen from A. fourcroyoides and A. cantala, or Manila-Maguey fiber from A. cantala. Some species provide a sap that is fermented to an intoxicating drink, called pulque in Mexico. Some contain agavesides.

I need to know the chemical composition of the agave piña bulbs after the leaves are removed and before entering the cooking or baking step. Any help?
Relevant answer
Answer
The simplest method is by preparing. Then you have to also find the best volume ratio either by chackingchecking previous research work or by conducting a lavoraboratory trial.
You can you can usecheck our latest publication to see the ratio we used and maybe try eat . your extract either by ethanol, methanol or aqueous maceration. Your choice of solvent will affect the time, and the efficiency of the extraction

Hi there!
Im working with hydrogels of agave lignin crosslinked with PEGDGE in alkali media but i need to wash them to quit the excess of reagents, when i wash them on water they swell and lose its structure, i tried on acid but the salt formation seems to be dehydrating the gels causing hornification, in which media could i wash my materials?
Thank you!

I have a question about the work published by Mills and Cowling: "How Fast Can Carbon Be Sequestered When Restoring Degraded Subtropical Thicket?" (https://www.researchgate.net/publication/264773087 )
I request help with any or all of the questions below.
1. The rates of CO2-absorption achieved by Agave and other species (Tables 1 and 2 of the reference above) seem rather high. Have these values been verified?
2. Does Spekboom hold any advantages over those species?
3. Which species of plants have the greatest propensity to capture CO2 from the atmosphere most rapidly over the short- to medium term (tens of months, rather than tens of years).

Regards, I need to make a comparison of the data obtained experimentally in the tests of compression, bending, thermal conductivity and specific heat of the mortar reinforced with randomly distributed cabuya fibers. Is there any mathematical equation?
Relevant answer
Answer
If you have enough date, that would be possible. Use any statistical software to do the comparison. Also, i think any equation is suitable for a specific material and for certain condations. It is deffecult to generalize a mathematical equation for all materials

It is not Agave sisalana where the leaf margin is not spiny.
This may be A. americana or A. salmiana where the leaf margin is spiny.

Most flowering stalks reach 7-8 feet but some are 3-4 feet tall with nothing observed of intermediate length. Shaw's agave is endemic to Southern California and Northern Mexico. It is considered endangered for several reasons. First, it has an inefficient reproductive strategy. Second, its habitat was threatened by erosion and by the border fence. Third, the indigenous people used to eat the reproductive parts of the plant thus interfering with its proliferation. One challenge of studying Shaw's is that the best examples grow on federal land, much of which is restricted to the public. Another problem is that few seem to care about the future of the plant. I have studied the morphology, distribution and life cycle of Shaw's agave for many years but I have more questions than answers. Can anyone help?
Relevant answer
Answer
first i would like to ask you is the species is dioecious or monoecious. secondly if the flowers borne on both the type of stalks are hermaphrodites you can check the dimorphism in traits like fertlity of pollen grains, pollen production and flower display per day in a reproductive season etc. If these characters are significantly varying then you can comment on dimorphism. I'll suggest you read articles by SCH Barrett. Definitely you'll get the idea.

I found some mites running on some Agave plants we have in our greenhouse (attached picture) and just got curious about their identity. They have about 17 spatulate setae around the edge of the dorsum of the idiosoma, and two rows of three spatulate setae along the centre of the dorsum. The legs and the gnathosoma are bright orange and the body is very dark blue.
Any idea about the family or anything else? They were found in central Mexico.
Thanks!
Relevant answer
Answer
They look like Bryobiinae - Tetranychidae, prob. genus Bryobia.
Philippe Auger would be a good researcher to help you.
There are also Acarologists in Mexico - you could ask Edith Estrada for a suggestion.

Women from rural areas in Swaziland are making sisal vaseline.
Relevant answer
Answer
Considering the question mentions the production of Sisal vaseline, I think the question is actually, could it be that the olive oil used extracts anti-microbial compounds.
I think if you want to know if there are anti-microbial compounds in the vaseline, you could try analyzing the vaseline itself. Then to determine whether the anti-microbials come from the sisal, or are already in the olive oil, you'd have to check the olive oil used separately and also make an extract of the sisal to check the presence of anti-microbials there.
But from the excellent answer from Boaz I think the answer would be, yes it is very well possible that the production method of Sisal vaseline, using olive oil, extracts active compounds (including anti-microbials) from the Agave.
