Analysis of growth and lipid production characteristics of Chlorella vulgaris in artificially constructed consortia with symbiotic bacteria
The aim was to study the effect of artificially constructed consortia of microalgae‐bacterial symbionts on growth and lipid production by Chlorella vulgaris (C. vulgaris), as well as the inter‐relationship between microalgae and bacterial in a photoautotrophic system. The results showed that compared to an axenic culture of C. vulgaris, H1 co‐culture system (axenic C. vulgaris‐Stenotrophomona smaltophilia) had the strongest effect on the C. vulgaris growth. The biomass, specific growth rate and maximum productivity of C. vulgaris were increased by 21.9, 20.4, and 18%, respectively. The bacteria in co‐culture syst...

Isolation and characterization of N2 ‐fixing bacteria from giant reed and switchgrass for plant growth promotion and nutrient uptake
The aims of this study were to isolate and characterize N2‐fixing bacteria from giant reed and switchgrass and evaluate their plant growth promotion and nutrient uptake potential for use as biofertilizers. A total of 190 bacteria were obtained from rhizosphere soil and inside stems and roots of giant reed and switchgrass. All the isolates were confirmed to have nitrogenase activity, 96.9% produced auxin, and 85% produced siderophores. Then the top six strains, including Sphingomonas trueperi NNA‐14, Sphingomonas trueperi NNA‐19, Sphingomonas trueperi NNA‐17, Sphingomonas trueperi NNA‐20, Psychrobacillus psychrodu...

A cold and organic solvent tolerant lipase produced by Antarctic strain Rhodotorula sp. Y ‐23
Psychrotolerant yeast Rhodotorula sp. Y‐23 was isolated from the sediment core sub‐samples of Nella Lake, East Antarctica. Isolate was screened for lipase production using plate assay method followed by submerged fermentation. Production optimization revealed the maximum lipase production by using palmolein oil (5% v/v), pH 8.0 and inoculum size of 2.5% v/v at 15 °C. The potential inducers for lipase were 1% w/v of galactose and KNO3, and MnCl2 (0.1% w/v). Final productions with optimized conditions gave 5.47‐fold increase in lipase production. Dialyzed product gave a purification fold of 5.63 with specific activi...

Artisanal tanneries: Potential application of inoculants formulated with lactic acid bacteria
In artisanal tanneries, the skins are immersed in cereals fermented by natural microbial flora in order to reduce the pH of the skin, an essential condition for carrying out the final step. The environmental thermal variation alters the fermentation process and affects the quality of the final product. The aim of this work was to isolate lactic acid bacteria from cereals mixture fermented in an artisanal tannery and to evaluate in vitro the acidifying activity of the strains as a first step for the formulation of a starter culture. In most samples, a prevalence of cocci (95%) was observed with respect to bacilli. The best ...

Transformation of cellobiose during the interaction of cellobiose dehydrogenase and β‐glucosidase of Cerrena unicolor
This work investigated the regulatory role of the interaction between cellobiose dehydrogenase (CDH) and β‐glucosidase (β‐GLU) in the conversion of cellobiose into cellobionolactone or glucose in vitro. To study the regulation, the two enzymes were isolated from the culture medium of the fungus Cerrena unicolor grown on a medium with microcrystalline cellulose. The enzymes were obtained in an electrophoretically homogeneous state. Their properties were studied. Both enzymes had acidic pH optima and were more stable in the acidic pH range. CDH was moderately thermostable, while β‐GLU had a low thermostability. Both...

Expression and characterization of the processive exo ‐β‐1,4‐cellobiohydrolase SCO6546 from Streptomyces coelicolor A(3)
The sco6546 gene of Streptomyces coelicolor A3(2) was annotated as a putative glycosyl hydrolase belonging to family 48. It is predicted to encode a 973‐amino acid polypeptide (103.4 kDa) with a 39‐amino acid secretion signal. Here, the SCO6546 protein was overexpressed in Streptomyces lividans TK24, and the purified protein showed the expected molecular weight of the mature secreted form (934 aa, 99.4 kDa) on sodium dodecyl sulfate‐polyacrylamide gel electrophoresis. SCO6546 showed high activity toward Avicel and carboxymethyl cellulose, but low activity toward filter paper and β‐glucan. SCO6546 showed maxi...

Taxonomy characterization and plumbum bioremediation of novel fungi
The objective of this study was to investigate the screening, taxonomy characterization, Pb biosorption, and application of the high Pb‐resistant fungus F1 separated from the heavy metal contaminated soil. Fungus F1 was screened through metal concentration gradient ranging from 25 to 4000 mg L−1. The internal transcribed spacers (ITS) of the strain was analyzed by molecular biotechnology. The adsorption conditions were also evaluated. The precipitation of fungus F1 was analyzed by Scanning Electron Microscopy (SEM), Fourier transformer infrared spectroscopy (FTIR) and energy dispersive X‐ray (EDX) techniques. The...
