Digestion of termiticide bait matricies by the pest termite Reticulitermes flavipes (Isoptera: Rhinotermitidae)
Journal of Economic Entomology
This study employed a novel approach to evaluate the digestibility of termite bait matrices and matrix components, with the aim of gaining new insights into bait attractiveness and efficacy. The idea behind this study was that termite baits that are easier to digest are more nutritious for termites. This may cause termites to eat more and spread active ingredients through their colonies through a process called trophallaxis.

Effects of five diverse lignocellulosic diets on digestive enzyme biochemistry in the termite Reticulitermes flavipes
Archives of Insect Biochemistry and Physiology
See publicationThis research utilized the lower termite Reticulitermes flavipes to examine changes in gut enzyme activity when feeding on five different lignocellulosic diets (cellulose filter paper [FP], pine wood [PW], beech wood xylan [X], corn stover [CS], and soybean residue [SB]). Our objectives were to compare the digestive enzyme activity of the whole gut and the contributions of host and symbionts to enzyme activity after feeding on these diets. We hypothesized that enzyme activities would differ…

Our objectives were to compare the digestive enzyme activity of the whole gut and the contributions of host and symbionts to enzyme activity after feeding on these diets. We hypothesized that enzyme activities would differ between diets as a way for termites and symbionts to optimally utilize variable resources.

Defining host-symbiont collaboration in termite lignocellulose digestion: "The view from the tip of the iceberg"
Communicative & Integrative Biology
We conducted translational-genomic studies in the lower termite Reticulitermes flavipes (Isoptera: Rhinotermitidae) and its symbiotic gut fauna to address these questions. We used both native gut tissue preparations and recombinant enzymes made from the host gut transcriptome to find out how the host and symbiont work together and how enzymes made by the host termite work with each other.

Multiple levels of synergistic collaboration in termite lignocellulose digestion
PLoS ONE
In this study, we employed translational-genomic techniques to gain unparalleled insights into digestion in the lower termite Reticulitermes flavipes and its symbiotic gut flora. Using native gut tissue preparations and recombinant enzymes made from the host gut transcriptome, we found interactions between the host and symbiont as well as between enzymes made only by the host termite.

Methods and systems for propagation of a microorganism using a pulp mill and/or a paper mill waste by-product, and related methods and systems
Issued US US20190071696A1
See patentThe present disclosure describes a method for using a source of one or more monosaccharides derived from pulp or paper mill waste by-products to propagate microorganisms such as yeast or bacteria. These microorganisms can then be used to ferment the monosaccharides into biochemicals, if desired. Additionally, the method includes the option of using a stillage composition in the propagation medium to facilitate propagation or to facilitate the enzymatic hydrolysis of oligosaccharides and/or…
The present disclosure describes a method for using a source of one or more monosaccharides derived from pulp or paper mill waste by-products to propagate microorganisms such as yeast or bacteria. These microorganisms can then be used to ferment the monosaccharides into biochemicals, if desired. Additionally, the method includes the option of using a stillage composition in the propagation medium to facilitate propagation or to facilitate the enzymatic hydrolysis of oligosaccharides and/or polysaccharides in pulp or paper mill waste by-products to form monosaccharides. This innovative approach offers a sustainable and cost-effective means of producing valuable biochemicals from waste materials.

Using dissolved oxygen to inhibit lactic acid production during propagation of yeast and/or hydrolysis of lignocellulosic biomass
Issued US US20190002940A1
See patentAccording to the present disclosure, a method for treating lignocellulosic biomass is provided. The method involves converting the cellulose in the lignocellulosic biomass into an oligosaccharide and/or a monosaccharide in the presence of an amount of oxygen that prevents the bacteria from producing lactic acid. This approach offers a unique and effective means of treating lignocellulosic biomass.
