Prospective of Microbial Exopolysaccharide for Heavy Metal Exclusion.
Appl Biochem Biotechnol
October 2017
Metals as a resource are depleting, and on another side, it fetches serious environmental pollution causing a threat to human health and ecosystem. The heavy metal accumulation due to anthropogenic activities results in toxicological manifestation. The traditional methods of remediation are not cost effective, efficient, and ecofriendly which necessitate and motivate towards the safe, effective, and ecofriendly biological methods.

Article Synopsis
- - This study investigates using parasites as a natural alternative to chemical insecticides for controlling mosquito larvae at various developmental stages.
- - Laboratory experiments showed that the third and fourth larval instars of certain mosquito species experienced significant infections leading to reduced movement and higher mortality rates.
- - The results suggest that these parasites could drastically lower adult mosquito emergence, indicating their potential use in mosquito biocontrol efforts.
Mosquitoes spread lethal diseases like malaria and dengue fever to humans. Considering mosquito vector control as one of the best alternatives to reduce new infections, here we have analyzed the effect of purified pigment prodigiosin extracted from Serratia marcescens (NMCC 75) against larval and pupal stages of Aedes aegypti and Anopheles stephensi mosquitoes. Mosquito larvicidal activities of purified prodigiosin revealed LC50 values of 14 ± 1.

To address this issue, the potential of synthetic and natural dye was investigated as sunlight protectants. Bt SV2 in absence of dyes when exposed to sunlight showed reduced effectiveness against the fourth instars of mosquito larvae.

Leaves and flowers extracts of plants from the families Rubiaceae (Ixora coccinea) and Apocynaceae (Allamanda violacea) were evaluated for mosquito larvicidal effect against early IVth instars of Aedes aegypti and Anopheles stephensi. Two forms of plant extracts, one untreated and the other treated with heat and proteolytic enzyme were used for assay.

- The ineffectiveness of current nematicides and the significant damage caused by nematodes highlight the need for natural solutions to control these pests.
- The pigment extracted from Serratia marcescens demonstrated effectiveness against juvenile stages of nematodes like Radopholus similis and Meloidogyne javanica, requiring lower concentrations than traditional treatments like copper sulfate.
- Analysis confirmed that the pigment contains prodigiosin, a bioactive compound, suggesting that microbial secondary metabolites may offer a promising approach for nematode management.
