The phrase "accessible substrate" is correct and usable in written English.
It can be used in contexts related to biology, materials science, or technology, where it refers to a surface or medium that is easy to reach or utilize.
Example: "The researchers found that the bacteria thrived on the accessible substrate, leading to faster growth rates."
Alternatives: "easily reachable surface" or "available medium".
That is, as a similar difference between hydrolysis with and without PEG is seen for a highly accessible substrate like PASC, the effect of PEG is not to increase substrate accessibility of Avicel for CBH I.
Methanol is an easily accessible substrate for the Methylobacterium sp. The endogenous control was also monitored for bacterial growth and a slight increase of OD was observed.
This kind of constant hydrolysis rate has been widely reported and thought to be the result of microbial attachment to all accessible substrate (Batstone et al. 2001).
The data suggests that under the pretreatment and process conditions used in this study the dilute acid pretreated Populus was a more accessible substrate for C. thermocellum fermentation compared to the pretreated switchgrass.
They hypothesized that an unknown component of the cellulase system (C1, the so called 'swelling factor') opens up the cellulose matrix, allowing this now more accessible substrate to be depolymerized by the truly hydrolytic enzymes (Cx) [ 10, 11].
The objective was to use this data in conjunction with imaging and sessile-to-planktonic cell yields to learn more about biofilm colonization and the relationship between accessible substrate surface area and cellulose conversion kinetics, as well as to determine the value of on-line gas measurements as an indicator of microbial activity and substrate digestibility.
The protocol makes use of easily accessible substrates derived from carboxylic acid, which display excellent efficiency and enantioselectivity towards direct amidation of prochiral sp3 C−H bonds.
Although ASP is not specific for immunotoxic gluten epitopes, it may potentiate gluten detoxification by cleaving larger proteins into short peptides that are accessible substrates for more specific endopeptidases and exopeptidases [12], [13].
On the other hand, Zygomycota such as Thermomucor indicae-seudaticae were classified as non-degraders based on their classification as fungi growing on easily accessible substrates [ 59, 60].
Such structures can be accessible substrates for the MR(X N nuclease complex or other nucleases, thereby making them susceptible to strand breaks.
Genomic DNA, mixed with a sizing standard, was elongated via capillary flow in a microfluidic device [ 66], and immobilized by electrostatic interactions with the positively charged surface, creating arrays of stretched, biochemically accessible substrates.
