Introduction
A biotechnologist and engineer with an MSc in entomology/phytopathology, and a PhD in the area of plant-fungus interactions awarded in 2018 from the Humboldt University of Berlin. Worked and gained hands-on experience at different biotechnology companies. Currently focuses on optimizing black soldier fly production with an emphasis on integrating insect farming into circular agricultural production systems.

With the worldwide industrialization of black soldier fly (BSF) production, it is necessary to better understand how the rearing scale and larvae density influence the performance of larvae and the quality of the final product. In this study, a factorial experiment was conducted to test the effect of rearing scale and density on the growth and comp...

In a method for producing a feed enriched with at least one carotenoid or a feed component enriched with at least one carotenoid, microorganisms are cultivated which produce and / or enrich at least one carotenoid. A microorganism biomass is hereby provided. This microorganism biomass is fed to insect larvae and the insect larvae are cultivated. Th...

Dark Septate Endophytes (DSEs) present a group of widespread root-colonizing fungi. The role of these endophytes in ecosystems and their interactions with plant pathogens are not well understood. In the current study, we assessed the antagonistic potential of the model DSE Cadophora sp. against the tomato soil-borne pathogens Rhizoctonia solani, Py...
Article
Full-text available
Background: Dark septate endophytes (DSEs) represent a form-group of ascomycetous fungi that inhabit the roots of a wide range of plant species, but our knowledge on their interaction with the host plants is still limited. Aims: This study was conducted to examine the effect of DSEs on the nutrition and growth of tomato (Solanum lycopersicum) in o...

Question
Greetings to all,
Does anybody know where I can find membranes with a mesh size that fungi could not be pass ? 
In my experimental system I need to grow a fungal colony in a "Tea bag" and avoid any fungal growth out of this tea bag compartment, I only want to have full exchange of nutrients and other compounds between the fungus containing compartment and the rest of the media. 
Did anyone try something similar ? any recommendation for a company which from which I can order such membranes ?
I appreciate your help and time, 
Question
Dear all, 
I was checking some tomato roots which should be colonized by fungal endophytes, I ended up seeing those Dark/pigmented structures, I stained my roots with Wheat Germ Agglutinin but nothing was stained at all, so I assume they are formed by the plant.
Does anybody know what could that be? could it be starch accumulation in root tissues ?
I appreciate any idea/assumption/advice which may lead me to knowing what that is .
P.S : Picture is fresh roots using normal light microscopy , 10X and 40X
Thanx in advance 
Question
I will do some work on different species belong to gen. Periconia and gen.  Phialophora, currently they are grown on solid PDA medium. I want to test different media to see whether I can get a faster growth .. 
I appreciate suggestions 
Question
After performing the IBD analysis using the "R" Package adegenet 1.4-0, the program obtains a histogram with X : simulated values , Y: permuted values , and a dot which is the correlation between geographical coordinates matrix and a matrix of genetic distances ...
In the figure I can observe that there is an isolation by distance since the correlation value is higher than most of the sim values ... could any one please give a brief distribution of what the sim values and the permuted values exactly are ??
Question
Acyrthosiphon pisum, or pea aphid, is considered to be the model aphid for studding symbiosis. It is known that its life cycle can be easily completed in a laboratory, and more information are available about its genetics and genomics.
Question
I need a method to extract Atropine from raw Belladonna Plants... Usually boiling plant roots in water or soaking them in acetone would extract Atropine as well as many other compounds which might be extremely toxic (other alkaloids such as scopolamine and hyoscyamine)
Is there a method to purify Atropine in a basic chemistry lab with commonly available chemicals and equipment?
