Efficient Cell Wall Composition Analysis
Cited 11 times
Recently, there have been methods published that report comprehensive analysis of cell wall components; for example Pettolino et al. [14 (link)] and Foster et al. [15 (link)]. Most of these methods usually involve relatively larger amounts of cell wall material which is ground into a fine powder. For example, Foster et al. [15 (link)] typically start with 60–70 mg dried AIR. Our analysis on the other hand typically stats with 10 mg stem material for wild type samples and 2 mg for irx mutants. The smaller amount of starting sample amounts and the deliberate avoiding of grinding steps to increase throughput means that not all of the side-analyses can be incorporated into our method. However, we do anticipate that an extraction of intact stems with 2 M trifluoroacetic acid (TFA) prior to acetic/nitric treatment can be performed to yield material for analysis of non-cellulosic polysaccharides with GC–MS [15 (link)].
The time of some steps could be further reduced with the use of additional equipment. For example, although our method means it is convenient to carryout the drying steps overnight; a vacuum desiccator or speed vac could be used for the drying steps to reduce time. Another potential time saving improvement could be performing the anthrone assay in a 96-well plate format. This will need an appropriate plate reader to be available which could be used with strong acids (67 % sulphuric acid). Additionally, it will also need 96-well plates that are resistant to 67 % acid at high temperature. However, both these variations have been previously used [15 (link)].

Quantification of Rhamnolipid Biosurfactants
Cited 7 times
Still pictures were taken with a gel doc imager (AlphaInnotech ChemiImager). Time lapse videos were acquired using a Marshall electronics v-1070 surveillance camera, set up in a room acclimatized to 37C. Swarming plates with fluorescently labeled strains were imaged using the Amersham Typhoon 9400 (GE Healthcare). Colony forming units (CFU) were estimated by plating serial dilutions with different strains distinguished by fluorescent color. Data points for number of cells in colony and rhamnose secreted measurements shown in plots represent the median value among all experimental replicates, with error bars representing the 95- and 5-percentile. Cell number ratios were determined by dividing the CFU number of one color by the CFU number of the other color. Error bars for such ratio measurements were estimated from binomial distribution fitting (Johnson et al., 1993 ). rhlA expression in swarming assays was assessed by quantifying the total GFP expression in swarming colonies of a strain containing the PrhlABGFP construct. The total colony fluorescence was measured in Photoshop and normalized by the fluorescence of a colony expressing GFP constitutively (promoter PA1/04/03GFP). Secreted lipids were extracted from growth supernatants using a chloroform/methanol extraction protocol adapted from (Caiazza et al., 2007 (link)). The rhamnolipids in the extract were measured using the anthrone colorimetric assay (Zhu & Rock, 2008 ). The amount of rhamnose in culture supernatant (47.4 mg/L for the WT grown for 24 h in the standard minimal medium) was calibrated using a rhamnose calibration curve. This was converted into rhamnolipid concentration applying a conversion factor of 3.0 to 3.2 (Camilios Neto et al., 2008 (link)), leading to the concentration of biosurfactants of 0.14–0.16 g/L. The concentration of dry mass of cells (0.717 g/L) was measured by gravimetry. Nalgene sterile analytical filter units (Thermo Fisher Scientific, Rochester, NY) with 0.2 μm pore size where pre-dried for 24 h at 65 C and used to filter 120 mL of culture. The filters where then dry for 48 h until mass became stable over time.

Comprehensive Starch and Sugar Analysis
Cited 6 times
Embryos and pericarps were removed from the dehulled grains, and the endosperms were ground to a powder. The starch content was measured using a starch assay kit (K-TSTA; Megazyme) according to the manufacturer’s instructions. Apparent amylose content (AAC) was measured according to the method described by Tan et al. (1999) (link). For analysis of soluble sugars with anthrone reagent, 50mg of powder was washed twice in 80% (v/v) ethanol at 80 °C for 40min. The supernatant was collected and diluted to a volume of 15ml with water. An aliquot (0.1–0.3ml) of this solution was analysed for sugar content using the anthrone method.
To determine the chain length distributions of amylopectin, 5mg of rice powder was digested with Pseudomonas amyloderamosa isoamylase (Sigma-Aldrich) and then analysed by high-performance anion-exchange chromatography with pulsed amperometric detection (HPAEC-PAD) using an ICS3000 model (Dionex) equipped with a pulsed amperometric detector and a CarboPac PA-20 column (Nagamine and Komae, 1996 ).

Soluble Sugar and Sucrose Analysis
Cited 6 times
Dried samples were ground to a fine powder for soluble sugar and sucrose analysis. The sample powder (~0.2g) with three replications was extracted using 6 mL of 80% (v/v) ethanol for 30 min in a water bath at 80°C, then the supernatant was collected after centrifugation at 5,000g for 10 min. This extraction procedure was repeated three times. The three supernatants were pooled and then diluted with 80% ethanol to 25 mL for the measurement of soluble sugar and sucrose content. Soluble sugar content was determined by using the anthrone reagent method and calculated based on the absorbance at a wavelength of 625 nm and a standard curve [39 (link)]. Sucrose content was measured by using the resorcinol method and estimated on the basis of the absorbance at a wavelength of 480 nm and a standard curve [40 (link)]. The mobilized soluble sugar content was calculated by the difference between the largest sugar content and the sugar content at 30 days after anthesis.

Biomass Enzyme Hydrolysis Optimization
Cited 6 times
Enzyme hydrolysis was performed in a 96-deep well format using the GLBRC Enzyme Platform (GENPLAT) as described earlier [4 (link),5 (link)]. Feedstocks were suspended and dispensed at 0.5% glucan, and final glucan loadings were 0.2%. Unless otherwise specified, enzyme loadings for all commercial benchmarks and for all mixture experiments were kept constant at 15 mg/g glucan, and reaction mixtures were incubated for 48 h at 50°C.
Design-Expert software (Stat-Ease Inc., Minneapolis, MN, USA) was used for experimental design and analysis. An augmented quadratic design was used throughout; thus, mixtures containing 6 and 16 components required 28 and 153 individual reactions, respectively. The lowest proportion of any enzyme in the core set (defined as CBH1, CBH2, EG1, BG, EX3, and BX) was set to 4%, because earlier studies indicated that for most of the core set, allowing them to go to 0% led to such poor Glc yields that reliable models could not be predicted [4 (link)]. The lowest proportion of all other enzymes ("accessory" proteins) was set to 0%. All assays were replicated once, sampled twice and assayed for Glc and Xyl twice, for a total of eight replicates of each mixture. Glc and Xyl were assayed colorimetrically [4 (link)]. Model predictions were tested experimentally as indicated in each table.
The monosaccharide composition of feedstocks was determined by the GLBRC Analytical Laboratory at Michigan State University. Briefly, samples were ground and washed sequentially with water, 70% ethanol, 1:1 chloroform:methanol, and acetone. The samples were then treated with amyloglucosidase + α-amylase, and the released Glc was quantitated as starch. The remaining material was then hydrolyzed with 2 N trifluoroacetic acid, and the released sugars were quantitated by GC of the alditol acetates. The insoluble residue from this step was treated with Updegraff's reagent, and the insoluble material was hydrolyzed with strong sulfuric acid and quantitated as cellulose using anthrone [16 (link),17 (link)].
The proteins in the commercial preparation Novozyme 188 and in β-mannanase (Megazyme catalog E-BMANN) were analyzed using standard mass spectrometry-based proteomics [3 (link)]. Scaffold version 01_07_00 (Proteome Software, Portland, OR, USA) was used to probabilistically validate protein identifications (DOE Joint Genome Institute) using the X!Tandem and ProteinProphet computer algorithms.

Reagent was used for the determination of the total sugar content of the enriched rice biscuit. One gram of the sample was hydrolysed with 5 mL of 2.5 N hydrochloric acid in a water bath for a period of three hours. It was allowed to cool and neutralized with Na2CO3 until effervescence ceased. The resulting mixture was made up to 100 mL and centrifugation was carried out for 5 min at 6000 rev per min. Anthrone reagent (4 mL) was added to the aliquot supernatant (1 mL), boiled in a water bath for 8 min, cooled and the resultant green to dark green colour was measured using a spectrometer (HITACHI spectrophotometer. Model: EA6000VX) at 630 nm. The absorbance value was compared with the standard curve of total carbohydrate and total sugar (glucose) was estimated as follows:

The Anthrone test is a simple method for the quantitative estimation of carbohydrates in different classes of samples like plant extracts, milk, blood serum, etc. The test was performed according to the mentioned protocol (Richards et al. 2020 (link)) with slight modifications. In brief, glucose stock solution (1 mg/ml) was prepared, and further diluted tenfold, glucose concentrations (200-1000 µg/mL) including an unknown sample (AZOME) extract.
Freshly, prepared (0.2%) anthrone reagent in Sulphuric acid of which 3 mL was added to each test tube. Tubes were kept at a temperature of 90°C for 10 min in a water bath. Meanwhile, the carbohydrate gets reacted with concentrated Sulphuric acid to form furfural. Then furfural reacts with the anthrone reagent to give different shades of bluish-green complex solutions. The absorbance was taken at 630 nm of all samples spectrophotometrically on a multi-mode microplate reader (synergy H1, BioTek, USA).

Quantifying Total Reducing Sugars
To quantify the total reducing sugars (TRS), a microplate adapted version of the anthrone-sulfuric acid method [30 (link)] was used. Briefly, 133 µl of anthrone solution (2 g/L anthrone in sulfuric acid) were added to 67 µl of each sample or the standard and mixed up and down with the micropipette in 96-well plates. The plates were heated to 95 °C for 10 min and allowed to cool for 10 min. Absorbance was measured in a microplate reader with a 630 nm filter. A glucose standard curve (15 to 350 µg/ml) was used for quantification. An internal standard of known concentration of CβG was included in each measurement to verify that the polysaccharide hydrolysis was complete. Results for CβG concentration were expressed as mg of glucose equivalents per L.
