Trichoderma Timelapse 2

Here's a timelapse of your favorite genus, Trichoderma! Although mushroom cultivators loathe this organisms for it's ability to rapidly destroy their crops, turns out Trichoderma has many valuable uses in biotechnology.
PerfectDay, for example, uses Trichoderma to produce dairy-free ice cream.

Despite being so quick to sporulate, I cant help but wonder why it waits such a seemingly predictable time to do so. I would expect it to jump right on it but always seems to make a certain diameter of growth first.

thats a great video thanks for posting it love time laps..yeah it grows about that fast it seams sometimes... also..as much as we hate her..the green bitch also has a lot of plant interactions as well and helps decompose wood, just like the mosquito feeds lots of bats birds and even fish...wish we could eliminate the bad parts.. like it killing a million people every year..

Didnt knew Trich can make more than making me worried about my crops.. Gotta Research that, maybe im cultivating the wrong stuff lol

Interestingly it looks to also be used actively in cannabis cultivation, at least based on this article: https://www.dinafem.org/en/blog/trichoderma-cannabis-cultivation-powerhouse-fungus/

Wow i remember some stuff from the past.. Some stuff looking Like active Carbon Pellets.. that stuff was pretty expensive.. 15β¬ for a tiny flask.. Like 10mg..

It most certainly is usually included in soil biota/mycorrhiza preparations
It doesn't make sense to me because wouldn't the trich overrun the mycorrizae in this situation anyway, meaning most formulations are snake oil, unless it is just VAM on it's own

Trich behaves differently in soil, a microbially diverse medium, as opposed to agar (here) or a mushroom substrate.
My guess is that trich doesn't compete for the same resources as other fungi when you're talking about soil and it is mostly harmful in sterile or pasteurized media.
This article examined trichoderma growth on lignocellulose-based substrates. It found that trich actually grew better if the substrate was sterilized and worse if the substrate was only immersed in hot water. That's an intriguing result; it suggests that trich might somehow be worse for mushrooms if there are no other microbes.
Quote:
Three different treatments were assayed: sterilization (121 Β°C), immersion in hot water (60 and 80 Β°C), and immersion in alkalinized water. Wheat straw, wheat seeds and Eucalyptus or Populus sawdust were used separately as substrates. After the disinfection treatments, bagged substrates were sprayed with 3 mL of suspension of conidia of Trichoderma sp (105 conidia/mL) and then separately spawned with Pleurotus ostreatus or Gymnopilus pampeanus. The growth of Trichoderma sp was evaluated based on a qualitative scale. Trichoderma sp could not grow on non-sterilized substrates. Immersions in hot water treatments and immersion in alkalinized water were also unfavorable treatments for its growth. Cocultivation with mushrooms favored Trichoderma sp growth. Mushroom cultivation disinfection treatments of lignocellulose substrates influence on the growth of Trichoderma sp when contaminations occur during spawning phase. The immersion in hot water at 60 Β°C for 30 min or in alkalinized water for 36 h, are treatments which better reduced the contaminations with Trichoderma sp during spawning phase for the cultivation of lignicolous species.
In the study, trich hardly grew at all in the non-sterilized substrates. In the sterile substrates it grew even better when mushrooms were introduced, suggesting it is actively a pathogen of them (but only in the pure cultures).
