Enhanced reducing sugar production by blending hydrolytic enzymes from Aspergillus fumigatus to improve sugarcane bagasse hydrolysis.

Biomass pretreatment for the production of second-generation (2G) ethanol and biochemical products is a challenging process. The present study investigated the synergistic efficiency of purified carboxymethyl cellulase (CMCase), β-glucosidase, and xylanase from Aspergillus fumigatus JCM 10253 in the hydrolysis of alkaline-pretreated sugarcane bagasse (SCB). The saccharification of pretreated SCB was optimised using a combination of CMCase and β-glucosidase (C + β; 1:1) and addition of xylanase (C + β + xyl; 1:1:1).

Optimization of Siderophore Production in Three Marine Bacterial Isolates along with Their Heavy-Metal Chelation and Seed Germination Potential Determination.

Siderophores are low-molecular-weight and high-affinity molecules produced by bacteria under iron-limited conditions. Due to the low iron (III) (Fe) levels in surface waters in the marine environment, microbes produce a variety of siderophores. In the current study, halophilic bacteria SMI_1, sp.

Biochemical Characterization of Thermostable Carboxymethyl Cellulase and β-Glucosidase from Aspergillus fumigatus JCM 10253.

Second-generation biofuel production has emerged as a prominent sustainable and alternative energy. The biochemical properties of cellulolytic enzymes are imperative for cellulosic biomass conversion into fermentable sugars. In the present study, thermostable CMCase and β-glucosidase were purified and characterized from Aspergillus fumigatus JCM 10253.

Assessment and evaluation of cellulase production using ragi (Eleusine coracana) husk as a substrate from thermo-acidophilic Aspergillus fumigatus JCM 10253.

The cellulase production by filamentous fungi Aspergillus fumigatus JCM 10253 was carried out using agro-industrial waste ragi husk as a substrate in the microbial fermentation. The effect of the process parameters such as temperature, substrate concentration, pH, and incubation process time and their interdependence was studied using response surface methodology. The optimum cellulase activities were obtained at 50 °C under the conditions with 1-2% of substrate concentration at pH 2-4 for the incubation period of 7-8 days.

Biochemical and kinetic characterization of laccase and manganese peroxidase from novel strains and their application in bioethanol production.

Laccase (lac) and manganese peroxidase (MnP) enzymes from the novel isolates, grown on lignin basic media (LBM) were purified by 80% ammonium sulphate fractionation, dialysis and DEAE-sepharose column chromatography. The optimum temperatures for laccase production were 60 °C, 50 °C and 50 °C and for MnP production were 50 °C, 70 °C and 60 °C from NITW715076_2, NITW715076_1 and NITW715076 isolates, respectively. The optimal pH for production was found to be 5 for production of both the enzymes from all the isolates.

A comprehensive review on perfusion method development for bone marrow collection and stem cell transplantation.

Bone marrow transplant (BMT) is done by the replacement of damaged bone marrow with healthy one. These healthy bone marrow cells (BMCs) are usually collected from the crest of the Ilium in humans hence these cells are used to replace damaged ones in the treatment of bone marrow related diseases such as leukemia, aplastic anemia, congenital immunodeficiency and autoimmune diseases. Even though there are different methods, perfusion method is one of the simple, safe and less contaminated methods used to harvest BMCs and it can reduce the risk in allogenic BMT.

Perfusion Method for Intra-bone Marrow Collection and Stem Cell Transplantation: A Critical Review.

A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Bone marrow is the soft, fatty tissue inside our bones. Bone marrow transplantation (BMT) is a powerful strategy for the treatment of leukemia, aplastic anemia, congenital immunodeficiency and autoimmune diseases.
