Valorization of municipal organic waste into purified lactic acid.

Municipal organic waste (biowaste) consists of food derived starch, protein and sugars, and lignocellulose derived cellulose, hemicellulose, lignin and pectin. Proper management enables nutrient recycling and sustainable production of platform chemicals such as lactic acid (LA). This review gathers the most important information regarding use of biowaste for LA fermentation covering pre-treatment, enzymatic hydrolysis, fermentation and downstream processing to achieve high purity LA.

Effective production of succinic acid from coconut water ( by metabolically engineered with overexpression of pyruvate carboxylase.

Succinic acid is an important acid which is used in medicine and pharmaceutical companies. Metabolically engineered strain was used for the effective production of succinic acid using water, which contained 5.00 ± 0.

Green seaweeds (Ulva fasciata sp.) as nitrogen source for fungal cellulase production.

In developing countries, local enzyme production can help decrease the dependency of imported enzymes for bioconversion of e.g. cellulosic feedstocks, but the use of conventional nitrogen sources contributes significantly to such enzyme production cost.

Enhanced production of succinic acid from methanol-organosolv pretreated Strophanthus preussii by recombinant Escherichia coli.

A biorefinery process for high yield production of succinic acid from biomass sugars was investigated using recombinant Escherichia coli. The major problem been addressed is utilization of waste biomass for the production of succinic acid using metabolic engineering strategy. Here, methanol extract of Strophanthus preussii was used for fermentation.

Green synthesis of gold and silver nanoparticles from (industrial hemp) and their capacity for biofilm inhibition.

Background: (hemp) is a source of various biologically active compounds, for instance, cannabinoids, terpenes and phenolic compounds, which exhibit antibacterial, antifungal, anti-inflammatory and anticancer properties. With the purpose of expanding the auxiliary application of in the field of bio-nanotechnology, we explored the plant for green and efficient synthesis of gold nanoparticles (AuNPs) and silver nanoparticles (AgNPs).

Methods And Results: The nanoparticles were synthesized by utilizing an aqueous extract of stem separated into two different fractions (cortex and core [xylem part]) without any additional reducing, stabilizing and capping agents.
