Biomass - Science topic
Biomass are total mass of all the organisms of a given type and/or in a given area. (From Concise Dictionary of Biology, 1990) It includes the yield of vegetative mass produced from any given crop.
Questions related to Biomass
Does anyone know where I can find the data of measured above-ground biomass? I need the data of forest biomass measured on the spot for training and learning. If possible, I can also invest money to purchase it. If anyone knows the data set of measured biomass, including the specific time and research area, please let me know, thank you.
As a part of my PhD research, I need to conduct a submersible vegetation survey and collect samples to determine the biomass. Can anyone guide me in this regard? I know one method called RAKE sampling.
In fact, I want to understand the amount of penetration or absorption of these two rays in the amount of algal biomass?Does UVA and B rays pass through my cultivation flask?
There is method available for determination of chemical composition of cellulose. However , I cannot find any method which shows the purity of the cellulose which is extracted from waste biomass. Kindly suggests the methods which measures the purity of cellulose.
Hello, researchers of biomass.
I believe many of you possess invaluable insights on this topic. Beyond basic introductory content, I am keenly interested in sourcing comprehensive resources that focus on lignin, cellulose, and hemicellulose and their correlation with the fuel properties of biomass pellets.
Any suggestion, commentary, or suggestion is welcome.
My major is not atmosphere research, it is inconvenient for me to use the professional model, e.g., GEOS-chem or WRF-chem. Though I know these models could measure the pollution from crop residue burning or other biomass sources with the help of related emission inventory. Are there simple ways to quantity the pollution of this part? Hope your response!
I prepared carbon materials from biomass waste. I studied preparation of carbon materials from biomass using a catalyst and without a catalyst in pyrolysis process. Catalytic pyrolysis leads to lower specific surface area, pore size and pore volume than non-catalytic process.
Please suggest some reasons.
Can I use the relative abundance of gene copies of my microbial samples (16S rRNA: for bacteria or ITS: for fungi) as a proxy for biomass?
My thought process (I know there are limitations):
Microbial Biomass of Taxon X = Relative Abundance of 16S rRNA (or ITS) Copies of Taxon X
Sum Biomass Across Taxa: Sum the biomass estimates for all taxa to obtain an estimate of total microbial biomass in my soil sample.
I am working on bioethanol production from lignocellulosic biomass. However, I require some clarification on the methods for calculating initial sugar concentration, sugar consumption rate, ethanol yield (in g/g and g/l). Could you please recommend simple calculations or protocols?
I have seen numerous excellent research papers where metallic nanoparticles are used as carriers for enzymes or acids in lignocellulosic biomass pretreatment. But is it possible where the nanoparticles alone will help in the breakdown of biomass into simpler sugars.
I want to convert biomass from herbaceous/grassland plants to carbon. Most of the formulas I have come across are formulas for trees/forests. I am looking for a formula for herbaceous plants.
We are working in the field of environmental pollution such as bioremediation, phycoremediation, phytoremediation, mushroom cultivation, biomass production, bioenergy production and various crops cultivation. Some experimental work is underway. But, another experimental work has been completed. Now we are going to prepare a scientific paper. But we are trying to analyze the data with the help of suitable or latest kinetic/mathematical model for the plant/biomass growth after the treatment process at different experimental.
I request all scientists and researchers who are working in this field. Please share your valuable knowledge, research papers, ideas, and text materials.
Thanks to all.
How do altitudinal gradients impact the biomass and carbon stock of coniferous forests?
Will the impact be significant or non-significant? If the effect is substantial how would conifer trees' growth response toward different elevations?
please suggest some valued work related to this topic preferably from Elsevier or Springer.
Dear Friends and collogues,
I am attempting to convert a certain quantity of biomass into its energy equivalent in kilowatt-hours (kWh). I have followed a specific procedure, but I am unsure if I am doing it correctly. I would greatly appreciate any assistance or guidance provided.
Here is an example of the calculation:
Biomass quantity= 17.62 Megagram
Conversion rate Megagram to KWh= 0.277778
high colorific value= 17.62 MG/kg
Therefore energy equivalent = 17.62*0.277778 * 17.62 = 88.28 KWh energy.
What is a species plays an important role in its community that is out of proportion with its biomass?
Forest litter was sampled from 1 x 1 m plots, weighed as W1 and a sub-sample was taken. The subsample was also considered as (W2) before being taken to the laboratory for oven drying. After the oven-dried, the subsample was weighed as the final weight (W3).
From the above, please how can I estimate the biomass?
I just want to know if it is possible to pool previously isolated and identified bacterial strains (biomass or DNA) and then making a metagenome-assembled genomes (MAGS) assembly, instead of sequencing the whole genomes one by one. I am pretty sure it would be a lot cheaper, but I do not know if that is a valid or accepted technique.

When I read publications devoted to the development of biomass equations, I find these three terms. While the first seems clear to me, the last two are incomprehensible to me. Sometimes I have the impression that the authors use them as synonyms, and others that they are completely different concepts. Please explain how I should understand these terms.

I would like help locating scientific information on the growth of Paulownia spp. in forest plantations. I am especially interested in the stock of biomass and CO2 for a given plantation age. Some web pages indicate these species as wonders and attribute them a stock of 1,500 t/ha (biomass) in 7 years. I have some doubts that this is true.
I look forward to your comments.
I have quantified the carbon biomass of entire Woody species having > 1 cm diameter in the parmanent observations plot(0.1 hectare ).While data has computed using allometric regression equation developed by FSI and other concern literature. Now I'm Little bit confused about the biomass conversation factors" Please enlighten me how we might be convert the biomass value of each tree species in the plot from kg/ha to mg ha - 1. Or other concern units with are applicable? Please enlighten about this carbon conversation unit dimension. Thanks for consideration ☺️🙏
