High energy demand driven by decreasing fossil fuels, and global warming because of the burning of fossil fuels necessitates the utilization of renewable and clean energy. One of these renewable energy sources is biodiesel. The increasing trend of biodiesel over the last 20 years tends to result in increasing glycerol (Gly), which is produced during the biodiesel production in 10% ratio (w/w) as a by-product. Using Gly as raw material is an alternative way to produce bio-based new products such as glycerol carbonate (GlyC).

Cost-efficient production of pullulan is of great importance but remains challenging due largely to the high-cost carbon sources. Lignocellulosic biomass is considered an alternative carbon source for industrial pullulan production, while new fungus producers that co-utilizing lignocellulose-derived glucose and xylose are required.

Due to the heterogeneous and isomeric nature of glycans, the development of an advanced separation of distinct glycan isomers is essential for glycan research and application. In this study, we utilized porous graphite carbon (PGC) chromatography for the separation of isomeric oligosaccharides without reduction or chemical derivatization at 190 °C in a custom-built heating oven.

Activated carbon (AC), a porous material with high pore volume, attracts increasing attention owing to its potential applications in several fields. The development of a porous structure in AC marginally relies on both the treatment methods and the type of precursor. Thus far, both renewable and nonrenewable precursor sources have been used to synthesize AC with high surface area and pore volume. This study presents the synthesis of AC via physicochemical treatment of waste oil fly ash (OFA), a waste material produced from power plants.

Species of the genus Halomonas are salt-tolerant organisms that have a versatile metabolism and can degrade a variety of xenobiotic compounds, utilizing them as their sole carbon source. In this study, we examined the genome of a Halomonas isolate from a hydrocarbon-contaminated site to search for chemosensory genes that might be responsible for the observed chemotactic behavior of this organism as well as for other responses to environmental cues.

This study analyzed Baker‟s yeast efficiency based upon its ability of growth on various agro-industrial wastes that act as the carbon source with an addition of nitrogen supplement at various growth parameters. Various locally available carbon sources including molasses, fruit bagasse juice, sugarcane bagasse juice and whey were used with inorganic as well as organic supplementation of corn steep liquor at a concentration of 50g/L. Increased productivity in case of the lab isolate was observed upon the use of organic supplementation @16.16%.

This study presents a new halophilic bacterial strain named Yangia sp. ND 218 which was isolated from the Giao Thuy mangrove, Nam Dinh Province, Vietnam which grew and accumulated PHA in a high salt medium. The possibility of designing an open (unsterile) fermentation process using Yangia sp. ND 218 was investigated.

An experiment was carried out to isolate, characterize and screening of Azospirillum from tuberose rhizoplane. 40 bacterial strains were isolated showing characteristics of Azospirillum. Isolates were characterized based on utilization of glucose, biotin requirement, acid production in glucose peptone broth and denitrification test. Out of 40 isolates, 20 isolates required biotin for their growth and remaining 20 showed growth without biotin. 16 isolates showed positive for denitrification and they were tentatively identified as Azospirillum brasilense.

Biogas is a carbon neutral, sustainable and renewable source of energy that can be produced and consumed without any adverse effect on the environment. Biogas has the potential to cater to the needs for cooking, basic fuel, electricity and can be upgraded to biomethane which then used as transportation fuel as well. The utilization of biogas as a fuel for thermal and engine applications and spent slurry as an organic fertilizer instead of chemical fertilizers contributes in reduction of greenhouse gas emission in both energy and agriculture sector.

Nine different yeast isolates from various parts of tomato plant were isolated from two different locations of Bengaluru. The population on tomato leaves varied from 2.01-3.5 x104 cfu/cm², on stems from 6.4-7.31 x104 cfu/g fresh weight and on fruits from 6.7-7.38 x104 cfu/g fresh weight. The yeast isolates were characterized for utilization of different carbon sources. Out of nine isolates, four yeast isolates TPL-I, RTPL, RTPS- II and RTPFII produced lipase enzyme. Further, they were evaluated for biocontrol activity against Alternaria solani in in vitro conditions.

Anaerobic microorganisms derive energy by transferring electrons from an external source or donor to an external electron sink or terminal acceptor and often have the capacity to reduce 2 or more terminal electron acceptors. The well-known type of microbial respiration, in which oxygen serves as an electron acceptor for the oxidation of organic carbon and/or hydrogen, has been studied elsewhere in detail.
