(IF 3.0) Pub Date : 2023-01-04 Hawaz, Estifanos, Tafesse, Mesfin, Tesfaye, Anteneh, Kiros, Solomon, Beyene, Dereje, Kebede, Gessesse, Boekhout, Teun, Groenwald, Marizeth, Theelen, Bart, Degefe, Ayantu, Degu, Sisay, Admasu, Alene, Hunde, Biru, Muleta, Diriba
Yeast strains tolerant to a wide range of stress conditions are needed for the production of bioethanol from substrates rich in sugar. In our earlier research findings, Meyerozyma caribbica isolate MJTm3 (OM329077) demonstrated remarkable stress tolerance and fermentative activity. The present study aimed to optimize six fermentation parameters to generate conducive fermentation conditions for ethanol

Cell phenotype changes and oxidative stress response in Vibrio spp. induced into viable but non-culturable (VBNC) state Ann. Microbiol. (IF 3.0) Pub Date : 2023-01-04 Prosdocimi, Erica M., Arioli, Stefania, Mapelli, Francesca, Zeaiter, Zahraa, Fusi, Marco, Daffonchio, Daniele, Borin, Sara, Crotti, Elena
Aquatic bacteria of the genus Vibrio include animal and human pathogens. The occurrence of Vibrio-related diseases has been associated with the current climate change-driven increase of sea surface temperature. Vibrio spp. can enter into the viable but non-culturable (VBNC) state, as a consequence of starvation in seawater at low temperatures. In such physiological state, Vibrio cells are no longer

The use of soil microbial potassium solubilizers in potassium nutrient availability in soil and its dynamics Ann. Microbiol. (IF 3.0) Pub Date : 2022-11-30 Olaniyan, Faridat Temilomo, Alori, Elizabeth Temitope, Adekiya, Aruna Olasekan, Ayorinde, Bisola Bolajoko, Daramola, Fisayo Yemisi, Osemwegie, Osarenkhoe Omorefosa, Babalola, Olubukola Oluranti
An increase in population has led to a higher demand for food. Meeting up this demand has necessitated the use of chemical fertilizers. However, utilization of these fertilizers has a considerable deleterious effect on the soil, plant, human, environmental sustainability, and only increase the cost and reduced profitability. With these identified problems, there is a need for efficient and sustainable

Combined anaerobic digestion of chicken manure and corn straw: study on methanogenic potential and microbial diversity Ann. Microbiol. (IF 3.0) Pub Date : 2022-11-29 Feng, Lei, Lin, Xiaoyu, Li, Xu
To explore the methane production potential and microbial community changes of combined anaerobic digestion of chicken manure and corn straw. Increase methane production, reduce the environmental pollution caused by the burning of livestock manure and straw, and provide some theoretical references for the construction and operation of actual biogas projects. Different proportions (3%, 5%, 10%) of corn

Process optimization for biosynthesis of pyruvate decarboxylase (PDC) and Neuberg’s ketol (PAC) from a novel Pichia cecembensis through response surface methodology Ann. Microbiol. (IF 3.0) Pub Date : 2022-11-22 Mushtaq, Zareena, Mukhtar, Hamid
Phenylacetylcarbinol (PAC) is an intermediate for the synthesis of several active pharmaceutical ingredients (ephedrine, pseudoephedrine, norephedrine, etc.) used for the production of antiasthematics and decongestants. An efficient biosynthesis of PAC through condensation of benzaldehyde and acetaldehyde catalyzed by a solvent tolerant pyruvate decarboxylase (PDC) is being reported. A process for

Effects of tobacco plant residue return on rhizosphere soil microbial community Ann. Microbiol. (IF 3.0) Pub Date : 2022-11-12 Chen, Jin, He, Jiguang, Zhang, Yang, Huang, Jie, Chen, Zhifeng, Zeng, Weiai, Deng, Xiaohua, Hu, Qiulong
Based on the recycling principle, returning of tobacco crop residues into the field is a common agronomic practice. However, comprehensive knowledge about the effects of tobacco plant residue return on the rhizosphere soil microbial community is very limited. After tobacco crop residue returning into the potted soil, 16S ribosomal RNA (rRNA) and internal transcribed spacer (ITS) amplicon sequencing

Microbial assembly and co-occurrence network in an aquifer under press perturbation Ann. Microbiol. (IF 3.0) Pub Date : 2022-10-29 Abiriga, Daniel, Jenkins, Andrew, Klempe, Harald
Thousands of aquifers worldwide have been polluted by leachate from landfills and many more remained threatened. Microbial communities from these environments play a crucial role in mediating biodegradation and maintaining the biogeochemical cycles, but their co-occurrence and assembly mechanism have not been investigated. Here, we coupled network analysis with multivariate statistics to assess the

Isolation and characterization of bioethanol producing wild yeasts from bio-wastes and co-products of sugar factories Ann. Microbiol. (IF 3.0) Pub Date : 2022-09-27 Hawaz, Estifanos, Tafesse, Mesfin, Tesfaye, Anteneh, Beyene, Dereje, Kiros, Solomon, Kebede, Gessese, Boekhout, Teun, Theelen, Bart, Groenewald, Marizeth, Degefe, Ayantu, Degu, Sissay, Admas, Alene, Muleta, Diriba
Yeasts are widely used for the production of bioethanol from biomasses rich in sugar. The present study was aimed at isolating, screening, and characterizing fermentative wild yeast recovered from bio-waste and co-products of Ethiopian sugar factories for bioethanol production using sugarcane molasses as a substrate. The wild yeasts were identified according to their cellular morphology and D1/D2 and

Co-fitness analysis identifies a diversity of signal proteins involved in the utilization of specific c-type cytochromes Ann. Microbiol. (IF 3.0) Pub Date : 2022-09-24 Ding, De-wu, Huang, Wei-fan, Lei, Li-lan, Wu, Pu
c-Type cytochromes are essential for extracellular electron transfer (EET) in electroactive microorganisms. The expression of appropriate c-type cytochromes is an important feature of these microorganisms in response to different extracellular electron acceptors. However, how these diverse c-type cytochromes are tightly regulated is still poorly understood. In this study, we identified the high co-fitness
