Abstract

This is a PDF file of an article that has undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability, but it is not yet the definitive version of record. This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Microbial Growth Rate Kinetics in Biogas Production by Anaerobic Digestion of Chicken Manure

“…To determine the initial cell or biomass concentration, 𝑋 𝑜 , 5ml of mixed sample was collected and charged into a small bottle and closed tightly. 𝑋 𝑜 was used together with 𝑆 𝑜 when computing Y X/S and procedures taken to obtain 𝑋 𝑜 at t = 0 is based on the serial dilution prior to the pour plate method of cell concentration (X) measurement, according to Equation 2 (Okpokwasili & Nweke, 2005;Shariful Islam et al, 2021).…”

The Perception of Consumers Towards Microalgae as an Alternative Food Resource in Bangladesh: A Contingent Valuation Approach

“…Spirulina has been extensively used for nutritional attributes as an alternative food supplement in the last three decades. Spirulina is the potential resource of fatty acids, amino acids, phytonutrients, antioxidants 15,16) , phycobiliproteins, minerals, and vitamins [17][18][19] .…”

Dynamical behaviour of single photobioreactor with variable yield coefficient

“…These types of models are commonly called constant yield models [ 6 ]. The specific growth rate of biomass in photobioreactors can be predicted using a number of well-known kinetic models such as Andrews [ 7 ], Contois [ 8 ], Logistics [ 9 ], Moser [ 10 , 11 ] and Teissier [ 12 ]. Cho et al.…”

“…If the yield coefficient is a function of the substrate concentration, limit cycles can be seen in specific situations [ 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 ]. Teissier [ 12 ], Nelson and Sidhu [ 24 ] studied the chemostat model with variable yield coefficient and specific growth rate function to find natural oscillations in the bioreactor. Motivated by their work, we propose and study a chemostat model with a modified growth rate function that has not been investigated by any scholar, as far as we know.…”
