1. Artificial neural network and regression coupled genetic algorithm to optimize parameters for enhanced xylitol production by Debaryomyces nepalensis in bioreactor

Author:
Pappu, Sharon Mano J.; Gummadi, Sathyanarayana N.

Subject:
Debaryomyces nepalensis; algorithms; biomass; bioreactors; fermentation; glycerol; neural networks; pH; prediction; regression analysis; system optimization; temperature; topology; xylitol; xylose
Abstract:
... In this study, prediction ability and optimization ability of regression and artificial neural network (ANN) models were compared. The input variables used to predict xylose consumption, biomass and xylitol production by regression analysis and neural network model are temperature, fermentation time, pH, kLa, biomass and glycerol of previous data points. Determination of coefficient (R²) was used ...

Subject:
feruloyl esterase; thermal stability; Aspergillus niger; lignocellulose; Komagataella pastoris; xylanases; xylooligosaccharides; industry; enzymatic hydrolysis; pH; hydrolysis; wheat bran; synergism; biomass; ferulic acid
Abstract:
... The enzymatic hydrolysis of lignocellulosic biomass has been studied for years, but this hydrolysis has been minimally used in the industry due to its high costs and low conversion yields. In the work reported here, ferulic acid (FA) and xylooligosaccharides (XOS) were generated from wheat bran at high yields based on the synergistic action of two xylan-degrading enzymes, xylanase (AnXyn11A) and f ...

Subject:
Planctomycetes; ammonia; anaerobic ammonium oxidation; biomass; genomic libraries; granules; inoculum; metagenomics; microbial communities; nitrifying bacteria; nitrites; nitrogen; particle size; ribosomal RNA; sludge; specific growth rate; total suspended solids; trace elements
Abstract:
... The anammox-enriched granular sludge was successfully formed during the long-term biogranulation experiment lasting over 330days. The cultivation was conducted at 30°C in a 10-L sequencing batch reactor (SBR) fed with synthetic medium containing ammonia, nitrite and trace elements. The properties of the developed granules were investigated in terms of the biomass activity (including the growth rat ...

4. Modelling and predicting transport and concentration distribution of sludge in a high performance anaerobic bioreactor

Author:
Dai, Ruobin; Chen, Xiaoguang; Ma, Puyue; Chu, Xiaoxiao; Xiang, Xinyi; Luo, Ying; Ni, Shengsheng; Li, Gang
Source:
Biochemical engineering journal 2017 v.120 pp. 17-24
ISSN:
1369-703X
Subject:
biogas; biomass; models; prediction; sludge; streams; upflow anaerobic sludge blanket reactor; wastewater
Abstract:
... The transport and concentration distribution of sludge in a high performance anaerobic bioreactor, termed spiral symmetry stream anaerobic bioreactor (SSSAB), was directly related to its effective retention of the biomass, as well as its stable operation under high loading rate. Therefore, the transport and concentration distribution of sludge in a lab-scale SSSAB were modelled and investigated in ...
