“…Considering the above applications, there has been an identification recently of several bio-organic waste materials from industries, for the production of biopesticides [96,[99][100][101][102][103]. All the raw material are rich in nutrient sources (carbohydrate and proteins) and lead to production of bacterial biopesticides (Bacillus sphaericus, Bs and B. thuringiensis subspecies P. israelensis, Bti), which are well known biocontrol agents used in mosquito vector control programs [17,51,104]. Besides, the fermentation process utilizing agro-industrial residues is nevertheless, an easy to follow, inexpensive technique, efficient enough to produce effective bacterial toxins lethal to disease transmitting mosquito vectors (Culex quinquefasciatus, Anopheles stephensi and Aedes aegypti).…”

Bacillus sphaericus Neide (B) and B. thuringiensis serovar israelensis (Bti) de Barjac provides effective alternatives to broad spectrum larvicides in many situations, with little or no environmental impact. Taking into account environmental benefits including safety for humans and other non-target organisms, reduction of pesticide residues in the aquatic environment, increased activity of most other natural enemies and increased biodiversity in aquatic ecosystems, their advantages are numerous. In addition to recombinant bacteria used as larvicides, research is also underway to develop transgenic algae and cyanobacteria using larvicidal endotoxins of Bti and Bs. The advent of recombinant DNA technology is now having an enormous impact on agriculture and medicine, and it is appropriate that the ability to manipulate and recombine genes with this technology be applied to improving larvicides for vector control. These new recombinant bacteria are as potent as many synthetic chemical insecticides, yet are much less prone to resistance, as they typically contain a mixture of endotoxins with different modes of action. The existing recombinants also have what can be considered disadvantageous, in that they do not show significantly improved activity against aedine and anopheline mosquitoes, in comparison to Bti. But it may be possible to overcome this limitation using some of the newly discovered mosquitocidal proteins, such as the Mtx proteins and peptides such as the trypsin-modulating oostatic factor, which could be easily engineered for high expression in recombinant bacteria. While other microbial technologies such as recombinant algae and other bacteria are being evaluated, it has yet to be shown that these are as efficacious and environment friendly as Bti and Bs. By combining the genes from a variety of organisms, it should ultimately be possible to design 'smart' bacteria that will seek out and kill larvae of specific vector mosquitoes. Thus, recombinant bacteria show excellent promise for development and use in operational vector control programs, hopefully within the next few years. documented [5,6]. Vector control is recognized as an effective tool for controlling tropical diseases. Several strategies have been adopted to control these dipteran pests, and to reduce vector-borne diseases. Synthetic insecticides have been effectively used during the past several decades for mosquito-control operations. But the chemical approach has several demerits, such as the development of insecticide resistance, environmental pollution, bio-amplification of contamination of food chain, and harmful effects to beneficial insects. Hence, there has been an increased interest in recent years, in the use of biological agents for mosquito control. Bio-Pesticides as Effective Tools for Mosquito Control In recent years, it has been witnessed, an increased interest in the usage of bio-pesticides as effective tool for mosquito control. Several bio-control agents were screened for their potency, mammalian safety and environmental imp...

“…The residue also contains a high quantity of phenolic compounds that might be harmful for human consumption [34]. As it is usually discarded as waste into the environment, butter sediments waste could represent a low-cost waste feedstock for biodiesel production and, as such, could be less of a burden for the environment [35]. Previously, ghee residue/clarified butter sediment waste was utilized for the cost-effective production of microbial lipases through solid-state fermentation.…”

“…produced high amounts of lipases, corresponding to 35.93 U/mg and 41.27 U/mg, respectively, when cultivated on solid ghee residue [31]. Clarified butter sediment waste from the dairy industry has also been used for cultivating bacteria ( Bacillus sphaericus and Bacillus thuringiensis serovar israelensis ) with biomass yields of 9.7 g/L and at a lower cost than with a conventional nutrient yeast extract salt medium [35].…”

The rising demand and cost of fossil fuels (diesel and gasoline), together with the need for sustainable, alternative, and renewable energy sources have increased the interest for biomass-based fuels such as biodiesel. Among renewable sources of biofuels, biodiesel is particularly attractive as it can be used in conventional diesel engines without any modification. Oleaginous yeasts are excellent oil producers that can grow easily on various types of hydrophilic and hydrophobic waste streams that are used as feedstock for single cell oils and subsequently biodiesel production. In this study, cultivation of Rhodosporidium kratochvilovae on a hydrophobic waste (clarified butter sediment waste medium (CBM)) resulted in considerably high lipid accumulation (70.74% w/w). Maximum cell dry weight and total lipid production were 15.52 g/L and 10.98 g/L, respectively, following cultivation in CBM for 144 h. Neutral lipids were found to accumulate in the lipid bodies of cells, as visualized by BODIPY staining and fluorescence microscopy. Cells grown in CBM showed large and dispersed lipid droplets in the intracellular compartment. The fatty acid profile of biodiesel obtained after transesterification was analyzed by gas chromatography-mass spectrometry (GC–MS), while its quality was determined to comply with ASTM 6751 and EN 14214 international standards. Hence, clarified sediment waste can be exploited as a cost-effective renewable feedstock for biodiesel production.
