Summary Background Throughout the COVID-19 pandemic, wastewater surveillance emerged as an important tool as an important tool by providing data that are more representative of the population than case reporting, which is often biased towards individuals with health-seeking behaviour or access to healthcare. With changing phases of the pandemic, decreased testing, and varying viral shedding rates, it is crucial to have a robust, sustainable, and flexible wastewater surveillance system that can serve as an independent signal of disease outbreaks. We aimed to identify {\textquoteleft}bellwether{\textquoteright} sewershed sites for sustainable disease surveillance in Bengaluru, India. Methods We conducted this longitudinal study from December 2021 to January 2024 at 26 centralised sewershed sites in Bengaluru city (\~{}11 million inhabitants). We quantified weekly SARS-CoV-2 RNA concentrations to track infection dynamics and identify {\textquoteleft}bellwether{\textquoteright} sewershed sites. This was achieved by integrating established metrics for wastewater analysis, calculating sample-to-sample percentage rate of change, and applying algorithms to differentiate signal from noise, thereby validating factors contributing to the precision and reliability of outbreak predictions. Findings Using 2873 wastewater samples, we applied a modified algorithm (COVID-SURGE algorithm) to identify {\textquoteleft}bellwether{\textquoteright} sewershed sites using longitudinal wastewater data on SARS-CoV-2 from 26 sewershed sites in Bengaluru. We utilised an Excel-based calculator (COVID-SURGE calculator) for user-entered wastewater data that differentiates signal from noise (underlying variability) based on the algorithm, with adjustments made to the input format of viral data and a specified limit of detection (LOD) value from the reverse transcriptase-quantitative PCR kit. We identified 11 {\textquoteleft}bellwether{\textquoteright} sites: four with large catchment sizes (KC Valley 1, KC Valley 2, Rajacanal, Doddabelee); four with medium sizes (Agaram, Nagasandra, KR Puram, Yelahanka); and three with small sizes (Chikkabegur, Chikkabanavara, Lalbagh). These were the best performers and can serve as a useful subset of sewage treatment plants for an early warning system at the city level. Interpretation Using wastewater metrics helps in selecting permanent sewershed sites and identifying sub-sites that can be scaled up during peak outbreak periods to detect disease hotspots, or scaled down during lean periods, especially when clinical data are unavailable. In a post-pandemic world, particularly in low-resource settings, focusing on the best-performing sewershed sites will ensure high-quality data that captures valid signals amid the noise from wastewater, conserves resources, and optimises public health actions beyond SARS-CoV-2.

Building capabilities to successfully commercialize biotech research into products or solutions, is paramount but challenging to develop, especially in developing ecosystems or countries. Once accomplished, they can turn-around the socioeconomic condition in such countries and make them self-reliant, at least in the healthcare sector. It may also encourage the incumbent research community to transform their research findings into scientific, entrepreneurial or commercial ventures. However, building such {\textquoteleft}innovation ecosystems{\textquoteright} in developing countries, requires scientific, financial and infrastructural support to overcome their existing barriers. In India, one such government-funded non-profit organization which is trying to overcome the existing barriers and building an ecosystem to encourage biotech innovation and entrepreneurship, is the Centre for Cellular and Molecular Platforms (C-CAMP). Since its inception, it has been able to support more than 90 biotech start-ups in funding, mentorship and incubation. In this paper, we start our discussion by understanding some of the major challenges faced by contemporary biotech organizations in India while commercializing their innovations. Subsequently, we attempt to understand how C-CAMP was conceptualized to overcome some of these barriers and how it evolved over the years, to become a nodal agency for inspiring biotech innovations and entrepreneurship. This case study highlights some of the best practices followed by C-CAMP in managing biotech innovation and commercialization. Top Management Teams in biotech-based academia, industry, government or venture capital funding agencies from any country may find these barriers and best practices worth studying and analyzing.

BACKGROUND: Krishna Tulsi, a member of Lamiaceae family, is a herb well known for its spiritual, religious and medicinal importance in India. The common name of this plant is {\textquoteright}Tulsi{\textquoteright} (or {\textquoteright}Tulasi{\textquoteright} or {\textquoteright}Thulasi{\textquoteright}) and is considered sacred by Hindus. We present the draft genome of Ocimum tenuiflurum L (subtype Krishna Tulsi) in this report. The paired-end and mate-pair sequence libraries were generated for the whole genome sequenced with the Illumina Hiseq 1000, resulting in an assembled genome of 374\ Mb, with a genome coverage of 61\ \% (612\ Mb estimated genome size). We have also studied transcriptomes (RNA-Seq) of two subtypes of O. tenuiflorum, Krishna and Rama Tulsi and report the relative expression of genes in both the varieties.

RESULTS: The pathways leading to the production of medicinally-important specialized metabolites have been studied in detail, in relation to similar pathways in Arabidopsis thaliana and other plants. Expression levels of anthocyanin biosynthesis-related genes in leaf samples of Krishna Tulsi were observed to be relatively high, explaining the purple colouration of Krishna Tulsi leaves. The expression of six important genes identified from genome data were validated by performing q-RT-PCR in different tissues of five different species, which shows the high extent of urosolic acid-producing genes in young leaves of the Rama subtype. In addition, the presence of eugenol and ursolic acid, implied as potential drugs in the cure of many diseases including cancer was confirmed using mass spectrometry.

CONCLUSIONS: The availability of the whole genome of O.tenuiflorum and our sequence analysis suggests that small amino acid changes at the functional sites of genes involved in metabolite synthesis pathways confer special medicinal properties to this herb.

Lathyrus sativus L. (Grass pea) is the source for cheap and nutritious food choice in drought and famine susceptible zones in greater part of North India and Africa. The non-protein amino acid β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) has been known for decades for its potent neurotoxic effect, causing irreversible neurodegenerative disease "neurolathyrism", present in both seed and leaf of Lathyrus sativus L. and other species in varying proportions. It is crucial to establish a rapid as well as reliable detection methodology for β-ODAP content in various Lathyrus plants. Currently available HPLC based methods involve multi-step derivatization of the sample. To overcome this, we have developed β-ODAP analysis method by HPLC without any prior derivatization. This method is statistically significant in the range of 2 to 100μg/ml and exhibited linear response with r2 \> 0.99. Limit of detection and quantitation of the later method was determined to be 5.56 μg/ml and 16.86 μg/ml, respectively. In addition to this, a TLC based method has also been developed. The limit of detection of β-ODAP is 0.6μg and for its substrate, L-1,2-diaminopropionic acid is 5μg. Both HPLC and TLC methods were validated by conducting in-vitro bioconversion test to detect the presence of biocatalyst in plant extract. This method is economical, rapid and simple.

Novel pinkish-orange pigmented, Gram-negative staining, half-moon shaped, non-motile, strictly aerobic strains designated AK24(T) and AK26 were isolated from water and sediment samples of Lonar Lake, Buldhana district, Maharahstra, India. Both strains were positive for oxidase, catalase and β-galactosidase activities. The predominant fatty acids were iso-C15:0 (41.5\%), anteiso-C15:0 (9.7\%), iso-C17:0 3OH (9.6\%), iso-C17:1 ω9c (10.2\%) and C16:1 ω7c/C16:1 ω6c/iso-C15:0 2OH (summed feature 3) (14.4\%). The strains contained MK-7 as the major respiratory quinone, and phosphatidylethanolamine and five unidentified lipids as the polar lipids. Blast analysis of the 16S rRNA gene sequence of strain AK24(T) showed that it was closely related to Aquiflexum balticum, with a pair-wise sequence similarity of 91.6\%, as well as to Fontibacter ferrireducens, Belliella baltica and Indibacter alkaliphilus (91.3, 91.2 and 91.2\% pair-wise sequence similarity, respectively), but it only had between 88.6 and 91.0\% pair-wise sequence similarity to the rest of the family members. The MALDI-TOF assay reported no significant similarities for AK24(T) and AK26, since they potentially represented a new species. A MALDI MSP dendrogram showed close similarity between the two strains, but they maintained a distance from their phylogenetic neighbors. The genome of AK24(T) showed the presence of heavy metal tolerance genes, including the genes providing resistance to arsenic, cadmium, cobalt and zinc. A cluster of heat shock resistance genes was also found in the genome. Two lantibiotic producing genes, LanR and LasB, were also found in the genome of AK24(T). Strains AK24(T) and AK26 were very closely related to each other with 99.5\% pair-wise sequence similarity. Phylogenetic analysis indicated that the strains were members of the family Cyclobacteriaceae and they clustered with the genus Mariniradius, as well as with the genera Aquiflexum, Cecembia, Fontibacter, Indibacter, and Shivajiella. DNA-DNA hybridization between strains AK24(T) and AK26 showed a relatedness of 82\% and their rep-PCR banding patterns were very similar. Based on data from the current polyphasic study, it is proposed that the isolates be placed in a new genus and species with the name Lunatimonas lonarensis gen. nov., sp. nov. The type strain of Lunatimonas lonarensis is AK24(T) (=JCM 18822(T)=MTCC 11627(T)).

Staphylococcus aureus is a major human pathogen, first recognized as a leading cause of hospital-acquired infections. Community-associated S. aureus (CA-SA) pose a greater threat due to increase in severity of infection and disease among children and healthy adults. CA-SA strains in India are genetically diverse, among which is the sequence type (ST) 772, which has now spread to Australia, Europe and Japan. Towards understanding the genetic characteristics of ST772, we obtained draft genome sequences of five relevant clinical isolates and studied the properties of their PVL-carrying prophages, whose presence is a defining hallmark of CA-SA. We show that this is a novel prophage, which carries the structural genes of the hlb-carrying prophage and includes the sea enterotoxin. This architecture probably emerged early within the ST772 lineage, at least in India. The sea gene, unique to ST772 PVL, despite having promoter sequence characteristics typical of low expression, appears to be highly expressed during early phase of growth in laboratory conditions. We speculate that this might be a consequence of its novel sequence context. The crippled nature of the hlb-converting prophage in ST772 suggests that widespread mobility of the sea enterotoxin might be a selective force behind its {\textquoteright}transfer{\textquoteright} to the PVL prophage. Wild type ST772 strains induced strong proliferative responses as well as high cytotoxic activity against neutrophils, likely mediated by superantigen SEA and the PVL toxin respectively. Both proliferation and cytotoxicity were markedly reduced in a cured ST772 strain indicating the impact of the phage on virulence. The presence of SEA alongside the genes for the immune system-modulating PVL toxin may contribute to the success and virulence of ST772.
