Many growers are beginning to use irradiation techniques (e.g. x-ray, electron beam, gamma) that promise to eliminate microbes without compromising quality. A microbial failure can cost growers [...]
There are currently no viable treatment options available for Hop Latent Viroid (HLVd) infected cannabis plants. Meristem tissue culture can be used to rescue infected plants, but the process can [...]
We continue to see several conflations and misconceptions voiced in the discussion about microbial safety standards for cannabis products. The foundation for these misconceptions is the idea that [...]
The State of Michigan is in the process of scrutinizing molecular methods and culture based methods for the detection of Total Yeast and Mold (TYM) on cannabis. They chose to run this study on [...]
30 live organisms were ordered from ATCC and tested for inclusion and exclusion testing on our TYM and TAC. All bacteria are positive for TAC and negative for TYM. 30 live organisms (fungal) were [...]
Excessive serendipity rusting the stoicism of a scientific mind Richard T. McKernan was an amazing father, leader, dry humor professional and exceptional businessman.A Nittany Lion engineer with [...]
In 2019, AOAC developed an SMPR for Aspergillus, E.coli, Salmonella detection on cannabis. These are three separate SMPRs. AOAC does not have an official SMPR for TYM but we can take what we have [...]
In 2020, a Michigan lab contacted us claiming our CFU/cq calculations were not matching their samples, nor did they match a recently released Candida albicans NSI Total Yeast and Mold (TYM) [...]
In 2015 we published a microbiome survey of medicinal cannabis flowers. We followed up this study with another publication in 2016 in the open access and open peer review platform F1000. Both of [...]
Cannabis testing labs are being presented with a wide variety of microbial testing solutions, each claiming they can shorten test times, increase sensitivity, and lower costs. Given microbial [...]
Any genome that doesn’t respond to our primers is sequenced to verify the organisms taxonomy. Fusarium proliferatum ATCC_76097 ATCC Accession 2x150bp Illumina Miseq assembled with Spades. [...]

Recently, some 450 cases of “vape pen” reported illnesses have allegedly contributed to six fatalities (NEJM). This health threat is serious, and tragic for its victims, but compared to the [...]
Angela Bacca authored an interesting article on the Jamaican Lion Genome project. As of 2019, all Kannapedia.net sequencing samples are mapped to the Jamaican Lion genome reference. [...]
The Boston Globe recently highlighted an important scientific debate ongoing in the Cannabis testing market of Massachusetts. Daniel Adams wrote this excellent piece on August 21st. On September [...]
The first whole genome shotgun assemblies of microorganisms were published in 1995. Since then over 313,000 genomes have been sequenced to varying degrees. DNA sequencing has become the new [...]
Introduction Science has a reproducibility crisis. As a result there is an active debate in the scientific community on how to improve the Peer Review process. Retraction rates are also on the [...]
On June 3rd, 2018 The DASH DAO funded Medicinal Genomics to finally crack the cannabis genome. Medicinal Genomics was the first company to sequence the cannabis genome in 2011 but the [...]
The DASH Distributed Autonomous Organization (DAO) has voted to fund the sequencing of a Type II cannabis plant and place this genome on a public blockchain with a novel crypto-incentivized, [...]
BLAST analysis of our STEC and general E.coli Primers Scroll down to see the more general E.coli Primer hits. Some are categorized as STEC, EHEC, ETEC, EPEC, etc.. but not all NCBI names are [...]
Botrytis cinerea Botrytis is a systemic mold infection in Cannabis. This mold is often called “Bud Rot” or “grey mold”. It can remain cryptic or dormant for long periods [...]
