A dendrimer enhanced CRISPR/Cas12a performance for the evaluation of acidogenic capacity in cariogenic bacteria

Interdisciplinary Medicine, Volume 4, Issue 4, July 2026.
A CRISPR/Cas12a‐powered dendritic DNA nanostructure is assembled to create confined enzymatic microdomains, enabling ultrasensitive detection. Integrated into a paper‐based origami biosensor, it allows equipment‐free on‐site quantification of acidogenic pathogens for the early diagnosis of dental caries.

Pleiotropic functions of catabolite control protein CcpA in Butanol-producing Clostridium acetobutylicum

BMC Genomics, 2012
Background Clostridium acetobutylicum has been used to produce butanol in industry. Catabolite control protein A (CcpA), known to mediate carbon catabolite repression (CCR) in low GC gram-positive bacteria, has been identified and characterized in C ...

Influence of substrate freshness on metabolite dynamics and methane emissions from pig slurry during laboratory incubation

Journal of Environmental Quality, Volume 55, Issue 4, July/August 2026.
Abstract Freeze/thaw pretreatment is commonly applied to animal slurry samples in laboratory studies, but its impact on organic matter transformation and methane (CH4) emissions remains uncertain. In this study, slurry incubations were performed at 20°C with three treatments differing in freshness of feces, urine, and inoculum.

EFFECT OF AMMONIA-NITROGEN ON ACIDOGENESIS IN ANAEROBIC DIGESTION

Doboku Gakkai Ronbunshu, 2000
嫌気性消化における炭水化物とタンパク質の分解に及ぼすアンモニアの影響を検討するため, 基質にデンプンとペプトンを用い, アンモニア性窒素濃度を変化させた回分実験を行った. その結果, ペプトンの分解速度は, ほとんど影響を受けなかったが, デンプンの分解速度は, アンモニア性窒素濃度の増大とともに大きく減少した. さらに, 炭水化物の代謝に及ぼすアンモニア性窒素の影響を検討するために, グルコースで培養した酸生成細菌を用いて回分実験を行ったところ, アンモニア性窒素濃度の増大に伴い, 分解したグルコース当たりの酪酸生成量は減少した. 一方, エタノールの生成は, アンモニア性窒素濃度の増大に伴い, 増加する傾向を示した.

A Comprehensive Review of the Key Factors Affecting Biogas Production From Anaerobic Digestion of Organic Waste

CleanMat, Volume 3, Issue 2, Page 74-98, June 2026.
Efficient conversion of organic waste to biogas depends on the coordinated optimization of feedstock composition, pretreatment, operational parameters, reactor design, and microbial community dynamics. This review highlights how these interacting factors improve methane yield and process stability, advancing anaerobic digestion as a practical pathway ...

Methane emissions from fresh dairy cattle and pig slurry

Journal of Environmental Quality, Volume 55, Issue 3, May/June 2026.
Abstract During manure storage, methane (CH4) is produced by anaerobic decomposition of organic matter by methanogens. Frequent removal and further processing of manure from the barn can reduce CH4 emissions. However, little is known about how much CH4 is lost during the adaptation of methanogens to the changing environment from the gut to storage. The

Advancement in Anaerobic Digestion for Scaling‐Up Biogas Production Through Food Waste Valorization

ChemBioEng Reviews, Volume 13, Issue 2, April 2026.
The review article begins with an introduction that covers the overview, food waste (FW) classification, and the steps involved in producing biogas through anaerobic digestion (AD). Following that, it describes the process for producing biogas, including single‐, two‐, and multistage systems, mesophilic and thermophilic digestion, and wet and dry ...
